How to fix crawlability issues for AI engines

You can have perfect schema, clean headings, and a brilliant answer, and if an engine's crawler cannot reach the page, none of it exists. Crawlability is the part everyone skips because it is invisible when it works and total when it fails.

This guide finds the door that is locked before you redecorate the room behind it.

What crawlability means here

Crawlability is whether a machine can actually fetch and read your page. AI engines use their own crawlers, separate from Google's, and the rules your site gives one are not automatically the rules it gives another.

So the failure mode is quiet: your page ranks fine in Google, looks healthy in your SEO dashboard, and is still unreachable to the crawler an AI engine sends. That is why this is the first thing to check when an engine skips you.

Do the task

Step 1: Read your robots.txt

Open yourdomain.com/robots.txt. Two things to check. Does it block the crawlers AI engines use, and does a broad Disallow accidentally cover the directory your key pages live in. People copy a robots.txt from a template and lock out more than they meant to.

Step 2: Confirm content is in the served HTML

View the page source, not the rendered page. Is your main content there in the HTML the server sends, or does it only appear after JavaScript runs? Some crawlers do not execute JavaScript, so content that depends on it can be invisible to them. If the source is nearly empty, that is your problem.

Step 3: Fix broken links and bad redirects

A crawler follows links. If a key page returns an error, or sits at the end of a redirect chain, or loops, the crawler gives up before it reaches the content. Find the dead ends and the chains and straighten them.

Step 4: Provide a current sitemap

Publish an up-to-date XML sitemap and reference it. It is a clean list of the pages you want found, which spares a crawler from having to discover them all by following links.

Step 5: Re-test what mattered

After the fixes, re-check each key page. Clean status code, content present in the source, no redirect detour. The point is not to fix in theory but to confirm the path is actually open now.

The old way and the new way

The old way assumed that if Google could crawl the site, everything could. One robots.txt, one mental model, one set of rules.

The new way treats AI engine crawlers as their own audience with their own access. You check what they specifically can reach, because a site can be wide open to Googlebot and quietly closed to the crawler behind an answer engine. Same site, different door, and only one of them was being watched.

The honest part

Crawlability is necessary and nowhere near sufficient. Open the door to a thin or confusing page and the engine simply confirms, faster, that there is nothing worth using. Fixing access does not fix content.

And making your pages reachable does not make an engine cite them. It removes the reason an engine could not use them. Whether ChatGPT, Perplexity, Gemini, or Claude then does is something we measure, not something we promise. The automated apply, with a preview and a per-fix approval, runs only through the connected Citedon plugin on WordPress. On other platforms the scan still flags the crawlability gaps and you fix them yourself, often in robots.txt and your redirects.

Where to start

Run a free scan and see whether the four engines can reach your key pages at all, before you spend another hour on schema for a page they cannot open. If access is the problem, fix that first. Everything else depends on it.
