What Is SEO and Why Does It Matter for Your Website?

In this article, you’ll learn what SEO is, why it still matters in a world increasingly shaped by AI-generated answers, and how to use it to drive sustainable traffic to your website. You’ll understand how search engines work behind the scenes, what makes content rank, and the specific steps you can take — from keyword research to link building to user experience — to outperform your competitors on Google. You’ll also learn how AI search is expanding the SEO playbook and what that means for your organic strategy going forward.

What Is SEO?

SEO (Search Engine Optimization) is the practice of improving your website’s content, structure, and authority so that search engines can understand it, trust it, and show it to people searching for what you offer.

The goal is straightforward: rank higher in search results so more of the right people find your website. That means more clicks, more leads, and more revenue — without paying for every visit.

For example, if you run a project management SaaS company, SEO can help your website appear on the first page of Google when someone searches “best project management tools.” The higher you rank, the more potential customers land on your site.

But SEO isn’t only about Google anymore. People are also asking questions to AI tools like ChatGPT, Perplexity, Claude, and Google’s AI Mode. These tools pull their answers from web content — often the same content that ranks well in traditional search. So the fundamentals of SEO now serve double duty: they help you rank on Google and get cited by AI answer engines.

This doesn’t mean SEO is dying. It means SEO is evolving. And the brands that understand both sides of the equation will compound their visibility while competitors scramble to catch up.

Why Is SEO Important?

SEO matters for two reasons that haven’t changed in two decades — and one new reason that most marketers are still underestimating.

Reason 1: People search for everything. Google processes over 8.5 billion searches per day. That includes people looking for products, services, comparisons, tutorials, local businesses, and answers to every question imaginable. That search demand creates a massive opportunity for any website that ranks well.

Reason 2: Organic traffic is free. Unlike paid advertising, where you pay for every click, the traffic you earn through SEO costs nothing once you’ve done the work. A well-optimized page can drive hundreds or thousands of visits per month for years — without ongoing ad spend.

Reason 3: AI search engines amplify the same content. Here’s what most articles about SEO won’t tell you: the content that ranks well in Google is often the same content that AI models cite when answering user questions. When ChatGPT or Perplexity recommends a product, it draws from indexed web pages — your web pages, if they’re authoritative enough.

This means SEO now delivers compounding returns across two channels: traditional search and AI search. A single blog post can rank on page one of Google and get cited in ChatGPT’s recommendations, multiplying its reach without any additional effort.

The result? Free, sustainable, and passive traffic from multiple sources — month after month.

How to measure the value of SEO traffic

To understand what your organic traffic is worth, look at what you’d have to pay if you were buying the same traffic through Google Ads.

For example, if your blog generates 10,000 visits per month from organic search, and the average cost-per-click for those keywords is $3.50, your SEO is delivering $35,000/month in equivalent ad value. That’s $420,000 per year — from content you created once.

This is why SEO remains the highest-ROI marketing channel for most businesses. The upfront investment in content and optimization pays off for months or years.

How Search Engines Work

To do SEO well, you need to understand how search engines decide what to show. This applies to Google, Bing, and increasingly to AI search engines that rely on the same underlying web content.

Search engines use two main components: a search index (a massive digital library of web page information) and search algorithms (programs that match your query to the most relevant results in that index and rank them).

These components work across three phases.

Crawling

Search engines use automated programs called crawlers (or spiders) to discover web pages. Crawlers follow links from page to page across the internet, downloading content as they go. Think of them as librarians who visit every bookstore in the world and bring copies of every book back to a central library.

If your pages don’t have links pointing to them, crawlers might never find them. That’s why internal linking and backlinks matter — they act as roads that crawlers follow to reach your content.

Indexing

Once a page is crawled, the search engine processes its content and adds it to the index. Indexing involves analyzing the text, images, and structure of a page to understand what it’s about.

Not every crawled page gets indexed. If a page has thin content, is a duplicate of another page, or has a noindex tag, it may be left out of the index entirely.

Ranking

When you type a query into Google, the search engine scans its index for relevant pages and then ranks them using an algorithm. The algorithm considers hundreds of factors — relevance, authority, freshness, user experience, and more — to determine which pages should appear first.

Nobody outside of Google knows the full algorithm. Google holds patents to protect its ranking formula, and the company is deliberately vague about the specific weight of each factor.

But they do leave clues. Google’s own “How Search Works” page confirms that the algorithm considers the words in your query, page relevance and usability, source expertise, and your location and settings. The weight of each factor changes depending on what you’re searching for — freshness matters more for news, while authority matters more for medical advice.

Here are seven ranking signals Google has publicly confirmed:

1. Backlinks — links from other websites pointing to your page

2. Relevance — how well your page matches the search intent behind a query

3. Freshness — how recently your content was created or updated

4. HTTPS — whether your site uses a secure connection

5. Mobile-friendliness — whether your page works well on mobile devices

6. Page speed — how fast your page loads

7. Intrusive interstitials — whether your page blocks content with large pop-ups

Google also personalizes results based on your location, language, and search history. Someone searching “plumber” in Austin sees different results than someone in London.

How AI search engines work differently

Traditional search engines return a list of links. AI search engines — ChatGPT, Perplexity, Claude, Google AI Mode, Copilot — return synthesized answers. They read, interpret, and combine information from multiple web sources to generate a single, conversational response.

But here’s the critical insight: AI search engines still rely on web content as their source material. They pull from the same pages that rank on Google. Perplexity, for example, actively crawls the web and cites its sources. ChatGPT draws from its training data, which comes from indexed web pages. Google AI Mode synthesizes content from its own search index.

This means the fundamentals of SEO — creating high-quality, authoritative, well-structured content — also determine whether your brand shows up in AI-generated answers. The difference is in how the content is presented: instead of ranking as a blue link on a results page, your content gets cited as a source inside a conversational answer.

The brands that understand this overlap have a significant advantage. They optimize once and get discovered twice — through traditional search and AI search.

How SEO Works

SEO works by creating content that is relevant, high-quality, and well-structured about topics people actually search for — and then proving to search engines that it deserves to rank.

Four things matter most:

1. Keyword research

2. Search intent

3. Content quality

4. User experience

Let’s break each one down.

1. Keyword research

Keyword research is the process of finding the specific words and phrases people type into search engines. It’s the foundation of every SEO strategy because without it, you’re creating content that nobody is looking for.

The goal is to find topics that meet two criteria: people are searching for them (search demand exists) and they’re relevant to your business (ranking for them could bring you customers, not just visitors).

Here’s how the process works:

Step 1: Start with seed keywords. These are broad terms related to your industry. If you sell accounting software, your seeds might be “accounting software,” “bookkeeping,” “invoicing,” “expense tracking.”

Step 2: Expand using a keyword research tool. Tools like Analyze AI’s Keyword Generator or a dedicated SEO platform will take your seeds and return hundreds of related keywords along with their search volume, keyword difficulty, and traffic potential.

Step 3: Filter and prioritize. Not every keyword is worth targeting. Filter by keyword difficulty (start with lower-difficulty keywords if your site is new), minimum search volume (no point targeting a keyword nobody searches for), and business relevance (will ranking for this term bring qualified visitors?).

Step 4: Pick keywords that match your site’s authority. A brand-new blog can’t realistically compete for “accounting software” (too competitive). But it might rank for “best accounting software for freelancers” or “how to track expenses without QuickBooks” — longer, more specific keywords where competition is lighter.

You can check keyword difficulty using Analyze AI’s free Keyword Difficulty Checker or check where any keyword currently ranks with the SERP Checker.

How to research what people ask AI search engines

Traditional keyword research tells you what people type into Google. But people are also asking questions to ChatGPT, Perplexity, and Claude — and those questions look different. They tend to be longer, more conversational, and more comparison-driven.

For example, instead of searching “best CRM software” on Google, someone might ask ChatGPT: “What’s the best CRM for a 10-person sales team that integrates with Slack and costs less than $50/user/month?”

These AI prompts represent a new layer of search demand. And the brands that track them can create content designed to be cited in AI-generated answers — not just ranked in Google’s results.

Analyze AI lets you track the specific prompts where your brand shows up (and where it doesn’t) across AI engines. The platform suggests relevant prompts based on your industry, so you don’t have to guess which questions matter.

You can also run ad hoc prompt searches to test whether your brand appears in AI answers for any question — across ChatGPT, Google AI, and Perplexity — instantly.

This is the new dimension of keyword research. Traditional keywords still matter. But prompt research — understanding what questions people ask AI tools and whether your brand is part of the answer — gives you a competitive edge that most companies haven’t started using yet.

2. Search intent

Search intent is the reason behind a search. Why did someone type this query? Were they trying to buy something, learn something, or find a specific website?

This matters because Google evaluates your content based on how well it serves the intent behind the query. If someone searches “how to make cold brew coffee” and you show them a page selling coffee makers, Google won’t rank you. The intent is informational, not transactional.

SEOs generally classify search intent into four categories:

How to identify search intent for any keyword

The easiest way to determine intent is to Google the keyword and study the top-ranking results. Ask yourself three questions:

What type of content ranks? Are the results blog posts, product pages, tools, or videos? If blog posts dominate, the intent is likely informational. If product pages dominate, it’s transactional.

What format do the results use? Are they how-to guides, listicles, comparisons, or step-by-step tutorials? This tells you the format Google thinks best serves the searcher.

What angle do the results take? Is there a common theme — like “for beginners,” “in 2026,” or “free”? That reveals what searchers care about most.

For example, if you search “avocado seed” and all the top results are how-to guides about planting avocado seeds, with angles like “easy” and “step-by-step,” then the intent is clear: people want a simple tutorial, not a scientific paper about avocado seed germination.

Matching search intent is non-negotiable. You can have the best content in the world, but if it doesn’t match what the searcher is looking for, it won’t rank.

How AI search engines interpret intent

AI search engines interpret intent differently. Because users ask questions in natural language — “What’s the most cost-effective project management tool for a remote team of 20 people?” — the AI doesn’t just match keywords. It interprets context, nuance, and constraints.

This means your content needs to answer specific, contextual questions, not just target broad keywords. Pages that provide detailed, scenario-based answers are more likely to be cited by AI models than pages that only cover surface-level information.

For example, a blog post titled “10 Best Project Management Tools” might rank on Google. But a post that also covers pricing tiers, team size fit, integration options, and remote work features is more likely to be pulled into an AI answer, because it addresses the layered, specific queries people ask in conversational AI tools.

3. Content quality

Google ranks individual pages, not entire websites. And over the years, it has developed detailed guidelines and ranking factors to evaluate page quality.

Three pillars define content quality in Google’s eyes: optimized content, E-E-A-T signals, and backlinks.

Optimized content

Content optimization is about what’s on the page. To outrank competitors, your content needs to be:

Helpful. It should thoroughly answer the question behind the keyword. Don’t just skim the surface — provide the depth a reader needs to take action. If someone searches “how to do keyword research,” they expect a step-by-step process they can follow, not a paragraph defining keyword research.

Easy to read. Use simple language and short sentences. Research suggests that roughly half of American adults read below a sixth-grade level. That doesn’t mean your audience is unintelligent — it means clear writing wins. Avoid jargon unless your audience expects it.

Well-structured. Use headings (H2, H3) to organize content into logical sections. Use paragraphs that address one idea each. Make your page easy to scan so readers can jump to the section they need.

Unique. If your content says the same thing as every other page ranking for the keyword, Google has no reason to rank you higher. Original data, unique frameworks, proprietary research, first-hand experience — these create what Google calls “information gain” and what we think of as a reason for your page to exist.

Fresh. For time-sensitive queries (“best SEO tools 2026”), freshness matters. Outdated content drops in rankings. For evergreen queries (“what is SEO”), freshness matters less — but regular updates still signal to Google that you maintain your content.

On top of the content itself, you need to follow basic on-page SEO best practices. Use your target keyword in the title tag, write a compelling meta description, add descriptive alt text to images, use header tags to create a clear hierarchy, and implement schema markup where appropriate. These small optimizations help search engines understand your page better.

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)

E-E-A-T is a set of quality guidelines that Google’s human evaluators use to assess search results. It’s not a ranking factor in the algorithmic sense — Google doesn’t have an “E-E-A-T score.” But the signals it measures strongly correlate with what the algorithm rewards.

E-E-A-T is especially critical for YMYL (Your Money or Your Life) topics — anything related to health, finance, safety, or major life decisions. Google applies extra scrutiny to these pages because bad information can cause real harm.

Here’s what each letter means:

Experience. Does the content creator have first-hand experience with the topic? A review of a software tool is more credible when the author has actually used it. A guide to hiking a trail is more trustworthy when the writer has hiked it.

Expertise. Does the author have relevant qualifications or deep knowledge? A medical article written by a doctor carries more weight than one written by a content marketer.

Authoritativeness. Is the website or author recognized as a go-to source for this topic? A cybersecurity article from a well-known security firm is more authoritative than one from a generic blog.

Trustworthiness. Is the website transparent, accurate, and legitimate? Does it have clear contact information, an about page, and proper citations? Trustworthiness is the most important component — Google explicitly says it sits at the center of the E-E-A-T framework.

The most impactful way to improve E-E-A-T is through backlinks — links from other credible websites pointing to your content. This brings us to one of the most powerful ranking factors.

Backlinks

Backlinks are links from one website to another. When a page on another site links to your page, it’s essentially a vote of confidence — it tells Google that your content is credible enough to reference.

Generally, pages with more backlinks from unique, authoritative domains tend to rank higher. Multiple studies have confirmed this, including research analyzing almost a billion web pages that found a clear correlation between the number of referring domains and organic search traffic.

Not all backlinks are created equal, though. The five factors that determine backlink quality are:

There are three main ways to get backlinks:

Earn them. Create content so useful or original that other websites link to it naturally. Original research, free tools, comprehensive guides, and unique data all attract links organically.

Build them. Proactively reach out to relevant websites and ask them to link to your content. This includes strategies like guest blogging, broken link building, the Skyscraper Technique (creating a better version of content that already has links, then asking those linkers to point to yours instead), and resource page outreach.

Create them. Submit your site to reputable directories, industry listings, and resource pages where adding your link is appropriate.

You can use Analyze AI’s Website Authority Checker to evaluate the authority of any domain, and the Broken Link Checker to find broken link building opportunities on competitor sites.

For a deeper dive, read our guide on link building tools.

How backlinks and citations work in AI search

In traditional SEO, backlinks are the currency of authority. In AI search, citations play a similar role. When an AI engine like Perplexity answers a question, it cites the web pages it used as sources. The more often your pages get cited, the more visible your brand becomes in AI-generated answers.

The mechanics are different from backlinks — you can’t build citations the way you build links. But the underlying principle is the same: authority, depth, and trustworthiness determine whether your content gets selected as a source.

With Analyze AI, you can track exactly which of your URLs are being cited by AI engines, how often, and in which models. The Sources dashboard shows which domains and content types AI platforms reference most in your industry — so you know where to focus your content efforts.

This data closes the loop between your content strategy and your AI search visibility. Instead of guessing whether your content is being referenced, you can see it directly and adjust accordingly.

4. User experience and usability

Google evaluates the user experience of every page through a set of page experience signals. The idea is simple: even if your content is great, a bad user experience will hurt your rankings.

Here are the signals Google openly measures:

Core Web Vitals (CWV). These are three metrics that measure loading speed, interactivity, and visual stability. Google uses them as ranking factors. You can check your scores using Google’s PageSpeed Insights.

HTTPS. Google prefers secure websites. If your site still runs on HTTP, switching to HTTPS (which is free via Let’s Encrypt) is one of the easiest SEO wins.

Mobile-friendliness. Google uses mobile-first indexing, which means it primarily uses the mobile version of your page for indexing and ranking. If your site doesn’t work well on phones, your rankings will suffer.

No intrusive interstitials. Large pop-ups that cover the main content — especially on mobile — can hurt your rankings. Cookie consent banners and age verification gates are exceptions.

You don’t need a cutting-edge visual design. You don’t need to be the fastest site on the internet. You need a site that loads reasonably fast, works on mobile, has a secure connection, and doesn’t bury content behind pop-ups. These are baseline standards for modern web design.

The Three Types of SEO

SEO is often broken into three categories. Understanding each one helps you know where to focus your efforts and where to bring in specialists.

On-page SEO

On-page SEO focuses on everything that happens on your web pages: the content itself, title tags, meta descriptions, headings, internal links, image optimization, and URL structure. It’s the most directly controllable type of SEO — you make changes to your own pages and see the impact.

The core of on-page SEO is aligning your content with search intent and making sure search engines can understand what your page is about. This includes using your target keyword naturally in the title, headers, and body text, as well as implementing proper internal linking to help search engines discover and understand the relationships between your pages.

Off-page SEO

Off-page SEO covers everything that happens outside your website that influences your rankings. The biggest factor here is backlinks, but it also includes brand mentions, social signals, and reviews.

Off-page SEO is fundamentally about reputation. When other credible websites link to you, mention your brand, or cite your content, it signals to Google that your site is trustworthy and authoritative. Building this reputation takes time and consistent effort.

Technical SEO

Technical SEO deals with the behind-the-scenes elements that help search engines crawl, understand, and index your site. This includes site speed optimization, XML sitemaps, robots.txt configuration, structured data markup, canonical tags, hreflang tags (for international sites), fixing crawl errors, and managing redirects.

Think of technical SEO as the foundation of a house. If the foundation is broken, it doesn’t matter how nice the walls are — the house won’t stand. Similarly, if search engines can’t properly crawl and index your site, even the best content won’t rank.

For a comprehensive breakdown, see our guide on the 18 types of SEO.

How Local SEO Works

Local SEO is a strategy focused on making your business visible in location-based search results. When someone searches “dentist near me” or “best Italian restaurant in Austin,” local SEO determines which businesses appear in the results.

Local SEO uses the same fundamentals as regular SEO — relevant content, authority, and good user experience — but adds several location-specific factors.

Google Business Profile. This is the single most important element of local SEO. Create and optimize your Google Business Profile with accurate business name, address, phone number, hours, categories, photos, and a compelling description. This profile powers your appearance in Google Maps and the local “map pack” that appears above organic results.

Reviews. Online reviews directly impact local rankings. Encourage satisfied customers to leave reviews on your Google Business Profile. Respond to reviews (both positive and negative) professionally. Review volume, recency, and average rating all influence where you appear in local results.

NAP consistency. Your business Name, Address, and Phone number need to be identical everywhere they appear online — your website, social media profiles, directories, and local listings. Inconsistencies confuse search engines and hurt your local rankings.

Local keywords. Use keyword research tools to find search queries with local intent in your area. Terms like “vet near me,” “[service] in [city],” or “[product] [neighborhood]” are signals that local SEO can capture this traffic.

Local citations and directories. Get your business listed in relevant online directories — both general ones (like Yelp and Yellow Pages) and industry-specific ones (like TripAdvisor for restaurants or Avvo for lawyers). Each consistent listing reinforces your local authority.

How AI Search Is Expanding the SEO Playbook

Here’s where most “what is SEO” articles stop. They cover Google, backlinks, and keywords — and leave it at that. But search is changing, and pretending it isn’t does you a disservice.

AI search engines — ChatGPT, Perplexity, Claude, Google AI Mode, Microsoft Copilot, and others — are growing fast. They don’t replace Google. They sit alongside it as a new organic channel. And they surface content differently.

Instead of showing ten blue links, AI search engines synthesize answers from web sources and present a single, conversational response. Your website either gets cited as a source inside that answer, or it doesn’t. There’s no “page two” of AI search.

This matters because AI search traffic is real and measurable. Companies are already seeing meaningful traffic from AI referrals — sessions that come from chatgpt.com, perplexity.ai, claude.ai, and copilot.microsoft.com.

The question isn’t whether to care about AI search. The question is whether you can measure it, and whether you’re doing anything to influence it.

What determines whether AI engines cite your content

AI models select sources based on many of the same qualities Google rewards: authority, depth, accuracy, freshness, and structure. But there are nuances:

Structured, clear content wins. AI models parse content to extract specific answers. Pages with clear headings, defined terms, and logical structure are easier for models to interpret and cite.

Comprehensive answers beat thin content. AI models prefer pages that answer a question fully, with context and specifics. A surface-level blog post is less likely to be cited than a detailed guide.

Authority still matters. AI models tend to cite well-known, authoritative sources. Building your domain authority through backlinks and quality content improves your chances of being selected.

Being mentioned frequently helps. If multiple sources on the web reference your brand, product, or content, AI models are more likely to include you in their answers. This is similar to how citations work in academic research.

For a deeper understanding of how AI engines select sources, read our research on how LLMs cite sources based on 83,670 citations.

How to track and improve your AI search visibility

You can’t improve what you can’t measure. That’s why tracking your brand’s visibility across AI engines is essential.

Analyze AI is built specifically for this purpose. It shows you where your brand appears across AI-generated answers, which competitors show up alongside you, and which prompts you’re winning or losing.

The Overview dashboard gives you a snapshot of your brand’s visibility, sentiment, and competitive position across all tracked AI models:

The Prompts dashboard tracks exactly which questions your brand appears in, your position in each answer, and which competitors are mentioned:

The Competitors view shows you who AI engines mention alongside your brand — and surfaces suggested competitors you might not have been tracking:

And the AI Traffic Analytics report connects your GA4 data to show you exactly how many visitors are coming from AI platforms, which pages they land on, and which AI sources drive the most sessions:

The Landing Pages report takes this further. It shows which of your pages receive AI-referred traffic, along with engagement metrics, bounce rates, and conversions — so you can double down on the content formats and topics that AI engines prefer:

This level of attribution lets you treat AI search as a real, measurable channel — not a guessing game.

How to use the Perception Map to position your brand

Beyond raw visibility metrics, understanding how AI engines portray your brand relative to competitors is equally important. Are you positioned as an industry leader, or mentioned as an afterthought?

Analyze AI’s Perception Map plots your brand and competitors on a two-axis grid measuring visibility and narrative strength. At a glance, you can see whether your brand sits in the “Visible & Compelling” quadrant (high visibility, strong narrative) or falls into a weaker position.

Clicking any competitor bubble reveals detailed battle card data: how often they appear, their typical rank, which prompts feature them, and what themes AI models associate with their brand. This intelligence lets you craft content that directly addresses the competitive gaps AI engines are highlighting.

How weekly emails keep your team informed

You don’t need to log in every day. Analyze AI sends weekly email digests with the most important changes: pages gaining or losing citations, competitor movements, visibility shifts, and actionable next steps — delivered straight to your inbox.

This keeps your entire marketing team aligned on AI search performance without adding another dashboard to monitor.

SEO Tools: What You Need to Get Started

You don’t need dozens of tools to do SEO well. You need two categories:

Google Search Console. This is a free tool from Google that provides your actual click, impression, and ranking data straight from Google’s index. It also notifies you of technical issues, manual actions, and indexing problems. Every SEO practitioner uses it because the data comes directly from Google, making it the most accurate source for your own site’s performance.

An all-in-one SEO platform. Google Search Console shows you your own data, but it can’t analyze competitors, do large-scale keyword research, audit your technical SEO, or track backlinks comprehensively. For that, you need a dedicated SEO tool that gives you competitive research, keyword discovery, site auditing, rank tracking, and backlink analysis in one place.

If you’re not ready to invest in a paid tool, you can start with free options. Analyze AI offers a suite of free SEO tools for key tasks:

For a more comprehensive list, check out our guide to the 29 best free SEO tools.

For AI search visibility specifically, you’ll want a tool that tracks your brand’s presence across AI answer engines, measures AI-referred traffic, and shows competitive intelligence in this new channel. That’s what Analyze AI is built for — and you can check your brand’s AI visibility for free.

How Long Does SEO Take?

SEO is a long-term investment, not a quick fix. Most practitioners report seeing meaningful results within 3 to 6 months, though this varies based on your site’s age, authority, competitive landscape, and the quality of your execution.

New websites with no existing authority face a longer ramp-up. They need time to build backlinks, establish topical authority, and earn Google’s trust. If you’re in a highly competitive industry, it may take even longer to outrank established players.

That said, this timeline is for traditional search results. AI search visibility can move faster because it’s a newer, less saturated channel. Brands that start tracking and optimizing for AI search now can gain a first-mover advantage while competitors are still focused exclusively on Google.

The key is consistency. SEO isn’t something you do once — it’s a continuous process of creating content, building links, fixing technical issues, and iterating based on performance data. The sites that invest consistently are the ones that compound their organic traffic over time.

How Much Does SEO Cost?

If you decide to hire help rather than do SEO yourself, here are the typical cost ranges:

The right choice depends on your budget, your team’s existing expertise, and how competitive your industry is. Small businesses with less competitive keywords can often handle SEO themselves with good tools and some learning. Enterprise companies in crowded markets typically need dedicated specialists or agencies.

Regardless of which path you choose, the ROI on SEO is difficult to match. A well-executed SEO strategy builds an asset — a stream of organic traffic — that continues delivering value long after the initial work is done.

FAQ

What is the difference between SEO, SEM, and PPC?

SEM (Search Engine Marketing) is the broadest term. It includes both organic traffic generation (SEO) and paid search advertising (PPC). SEO focuses on earning traffic through unpaid rankings. PPC (Pay-Per-Click) focuses on buying traffic through ads. Most marketing strategies use both, but SEO delivers better long-term ROI because the traffic doesn’t stop when you stop paying.

What are the main types of SEO?

There are three main types: on-page SEO (optimizing page-level elements like content, title tags, and internal links), off-page SEO (building authority through backlinks, brand mentions, and external signals), and technical SEO (ensuring search engines can crawl and index your site properly). Subtypes include local SEO, ecommerce SEO, and enterprise SEO. For a complete breakdown, see our guide to 18 types of SEO.

Can I do SEO on my own?

Yes, especially if you run a small or medium-sized website. SEO is a learnable skill, and most of the core tactics — keyword research, on-page optimization, content creation, internal linking — don’t require a specialist. You’ll need some time to learn the fundamentals and good tools to work with. As your site grows, you may want to bring in specialists for technical SEO or link building.

Is SEO still worth it in 2026?

Absolutely. Google still drives the vast majority of organic traffic for most websites, and AI search engines are emerging as an additional channel that rewards the same content fundamentals. SEO isn’t dying — it’s evolving. The brands that invest in both traditional SEO and AI search visibility are positioning themselves for compounding organic growth across multiple channels.

What is the difference between SEO and GEO?

GEO (Generative Engine Optimization) is a newer term that refers to optimizing your content for AI-generated search answers — like those from ChatGPT, Perplexity, or Google AI Mode. The key insight is that GEO isn’t a replacement for SEO — it’s an extension of it. The same content qualities that help you rank on Google (depth, authority, structure, freshness) also determine whether AI engines cite your content. We think of AI search as the next evolution of organic visibility, not a separate discipline.

How do I know if my brand shows up in AI search results?

You can manually test this by asking ChatGPT, Perplexity, or Google AI questions relevant to your industry and seeing if your brand is mentioned. For systematic tracking, tools like Analyze AI monitor your brand’s visibility across all major AI engines automatically, tracking which prompts mention you, your position in responses, and how your visibility changes over time.

What SEO trends should I follow?

Focus on these four trends that are delivering measurable results: AI search optimization — tracking and improving your visibility in AI-generated answers is becoming essential. Content depth over content volume — Google and AI models both reward comprehensive, authoritative content over high quantities of thin pages. E-E-A-T signals — demonstrating real experience, expertise, and trustworthiness matters more than ever for ranking. Information gain — creating content that adds something genuinely new to the conversation (original data, unique perspectives, first-hand experience) is how you stand out in a world where AI can generate generic answers instantly.
