Fix Crawl Issues
TL;DR
Crawl issues prevent AI systems from discovering your content even when your robots.txt allows access. Broken sitemaps, redirect chains, missing canonical tags, and weak internal linking all reduce your site's visibility to AI crawlers.

Checking Your Sitemap#
Your XML sitemap is a roadmap for crawlers. It lists every page you want discovered and tells crawlers when each page was last updated. If your sitemap is broken, incomplete, or outdated, AI crawlers may miss important content.
Start by checking whether your sitemap exists. Visit
https://yourdomain.com/sitemap.xml. If you get a 404 error, you need to create one. Most CMS platforms (WordPress, Shopify, Squarespace) generate sitemaps automatically, but they may need to be enabled in settings.
If your sitemap exists, audit its contents. Every important page on your site should be listed. Check that no URLs return 404 errors, 301 redirects, or 500 errors. A sitemap that points to broken pages signals poor site maintenance to AI crawlers.
Verify that your <lastmod> dates are accurate. If every page shows the same date, or dates from years ago, crawlers cannot determine freshness. Update lastmod whenever you meaningfully change a page's content. This feeds into your crawl health factor score.Well-structured XML sitemap example

Fixing Redirect Chains#
A redirect chain happens when page A redirects to page B, which redirects to page C, which finally loads the content. Each hop adds latency and increases the chance that a crawler gives up before reaching the final page.
AI crawlers have limited patience for redirect chains. Most follow two or three redirects at most. If your site has chains longer than that, content at the end of the chain may never get crawled.
Audit your redirects using a crawler tool like Screaming Frog, Ahrefs Site Audit, or Google Search Console. Look for chains of three or more hops and fix them by pointing the first redirect directly to the final destination. For example, if
/old-page redirects to /renamed-page which redirects to /final-page, update the first redirect so /old-page goes straight to /final-page.
Also check for redirect loops — circular redirects where page A redirects to page B, which redirects back to page A. These are crawl black holes that waste crawler budget and block access entirely. Fix loops immediately when found.Adding Canonical Tags#
Canonical tags tell crawlers which version of a page is the authoritative one. Without them, AI systems may see duplicate content across multiple URLs and either pick the wrong version to cite or discount your content entirely.
Duplicate content is more common than most site owners realize. URL parameters (
?sort=price), trailing slashes (/page vs /page/), HTTP vs HTTPS versions, and www vs non-www variants can all create duplicate pages. Each duplicate dilutes your authority.
Add a canonical tag to every page on your site. It goes in the <head> section and points to the preferred URL for that content. The canonical URL should be the clean, parameter-free, HTTPS version of the page.Canonical tag implementation
<!-- Add this to the <head> of every page -->
<link rel="canonical" href="https://www.example.com/blog/ai-readiness-guide" />
<!-- For paginated content, each page canonicalizes to itself -->
<link rel="canonical" href="https://www.example.com/blog?page=2" />
<!-- Do NOT point all paginated pages to page 1 -->html
Internal Linking Strategy#
Internal links are how crawlers discover pages beyond your sitemap. A strong internal linking structure ensures that every important page is reachable within two or three clicks from your homepage.
Audit your internal links by mapping which pages link to which. Look for orphan pages — pages with no internal links pointing to them. Orphaned pages are effectively invisible to crawlers that follow links rather than sitemaps. Fix orphans by adding relevant links from related content.
Use descriptive anchor text for internal links. Instead of "click here" or "read more," use text that describes the linked page. "Read our guide to schema markup" tells AI crawlers what to expect at the destination, which improves both crawl efficiency and content understanding.
Create content hubs where related pages link to each other. For example, a main topic page should link to all subtopic pages, and each subtopic should link back to the main page and to related subtopics. This hub-and-spoke structure helps AI understand the relationships between your content and builds topic clarity.

Frequently Asked Questions
How often should I update my sitemap?
Your sitemap should update automatically whenever you publish, update, or delete a page. Most CMS platforms handle this automatically. If yours does not, set a weekly manual update schedule. The key is that your sitemap always reflects your current site structure.
Are redirect chains always bad?
One redirect is normal and fine — for example, redirecting an old URL to a new one. The problem starts with chains of three or more hops. These slow down crawling, waste crawler budget, and risk the crawler abandoning the chain before reaching your content.
How do I find orphan pages on my site?
Use a crawler tool like Screaming Frog or Ahrefs Site Audit. Crawl your entire site starting from the homepage and compare the discovered URLs with your sitemap. Any page in the sitemap that was not found by the crawler is likely an orphan with no internal links pointing to it.
