Question 1

What is a broken link and how does it affect SEO?

Accepted Answer

A broken link (also called a dead link or 404 error) is a hyperlink that points to a page that no longer exists or returns an error. Broken links affect SEO in three ways: (1) They waste crawl budget — search engine bots spend time on dead ends instead of indexing useful pages, (2) They break link equity flow — if external sites are linking to a page on your site that returns a 404, you lose the ranking value of those backlinks, and (3) They harm user experience — visitors who encounter broken links lose trust in your site, increasing bounce rate.

Question 2

What is a Page Score and how is it calculated?

Accepted Answer

The Page Score is a 0–100 metric that evaluates the overall technical health of a webpage. It factors in broken links (internal and external), page loading performance, meta tag completeness, content-to-HTML ratio, render-blocking resources, mobile-friendliness indicators, and other technical SEO signals. A score of 90–100 indicates excellent health, 70–89 is good but has room for improvement, 50–69 needs attention, and below 50 suggests serious technical issues that are likely hurting search performance.

Question 3

What is the difference between internal links and external links in SEO?

Accepted Answer

Internal links connect pages within the same domain (e.g., your homepage linking to your blog). They help search engines discover and crawl your content, distribute link equity (ranking power) across your site, and establish content hierarchies. External links (also called outbound links) point from your site to other domains. They signal content quality and topical relevance to search engines when they link to authoritative sources. Both types of links are essential for SEO — a healthy page typically has a strong internal link structure and a few relevant external links to trusted sources.

Question 4

How often should I check my website for broken links?

Accepted Answer

Check your most important pages (homepage, top landing pages, highest-traffic blog posts) monthly. Run a full site-wide broken link audit quarterly. Additionally, always run a check after site migrations, CMS updates, URL structure changes, or content deletions — these are the most common events that create broken links. For large sites with thousands of pages, consider scheduling weekly automated crawls to catch new broken links before they accumulate.

Question 5

What are render-blocking resources and why do they matter?

Accepted Answer

Render-blocking resources are CSS stylesheets and JavaScript files that prevent a browser from displaying the page until they are fully loaded. They slow down the time to first meaningful paint — the moment a user sees actual content. This directly impacts Core Web Vitals metrics like Largest Contentful Paint (LCP) and First Contentful Paint (FCP), which Google uses as ranking factors. Fixes include deferring non-critical JavaScript, inlining critical CSS, and using async loading for non-essential scripts.

Question 6

What does "Low Content Rate" mean in the issues report?

Accepted Answer

Low Content Rate (also called low text-to-HTML ratio) means the page has very little readable text content relative to its HTML code. Search engines may interpret this as a thin content page that provides limited value to users. The typical healthy ratio is above 25% text to HTML. Pages heavy on JavaScript frameworks, large navigation menus, or excessive ads can trigger this issue. The fix is to ensure each page has substantial, unique, informative text content that serves the user's search intent.

Question 7

Can broken links on my site affect pages that don't have broken links themselves?

Accepted Answer

Yes, through a concept called crawl budget waste. Search engines allocate a limited crawl budget to each site — the number of pages they will crawl per visit. When bots encounter broken links, they follow them to dead ends, using up crawl budget that could have been spent indexing your good pages. On large sites (10,000+ pages), excessive broken links can cause important new content to be discovered and indexed more slowly, indirectly harming the rankings of perfectly healthy pages.

Question 8

Should I fix internal broken links or external broken links first?

Accepted Answer

Fix internal broken links first. Internal broken links directly impact your site's crawlability, user navigation, and internal link equity distribution — all of which you fully control. External broken links (links from your page to other sites that have gone down) matter too, but their impact is less severe. For external broken links, either remove the link, replace it with a link to an updated source, or use the Wayback Machine to find archived versions of the content.

Question 9

What is link equity and how do broken links affect it?

Accepted Answer

Link equity (formerly called "link juice") is the ranking value passed from one page to another through hyperlinks. When an authoritative site links to your page, it passes link equity that helps your page rank higher. If that link points to a page on your site that returns a 404 error, the link equity is wasted — it flows into a dead end. By finding broken inbound links and setting up 301 redirects to relevant live pages, you can reclaim this lost link equity and improve your rankings.

Question 10

How do I use broken link data for link building?

Accepted Answer

Broken link building is a proven link acquisition strategy. Find broken pages on competitor or industry sites using a broken link checker. Then create content on your own site that covers the same topic as the dead page. Finally, reach out to the websites that were linking to the broken page and suggest they replace the dead link with a link to your live, relevant content. This strategy works because you're helping webmasters fix a real problem while earning a backlink.

Question 11

What HTTP status codes indicate broken links?

Accepted Answer

The most common broken link status codes are: 404 (Not Found — the page doesn't exist), 410 (Gone — the page was intentionally removed), 500 (Internal Server Error — the server failed), 502 (Bad Gateway), and 503 (Service Unavailable). Additionally, 301 (Permanent Redirect) and 302 (Temporary Redirect) aren't "broken" per se, but redirect chains (multiple redirects in sequence) waste link equity and slow page loads. This tool detects all of these status codes and categorizes them by severity.

Question 12

Can broken links cause Google to de-index my pages?

Accepted Answer

A few broken links won't cause de-indexing. However, if a significant percentage of your site's URLs return 404 errors, or if critical pages linked from your navigation consistently fail, Google may reduce its crawl rate for your domain and flag your site as poorly maintained. In extreme cases where broken links create orphaned pages (pages with no valid links pointing to them), those specific pages may be dropped from the index. Regular broken link auditing prevents this degradation.
