AI-crawler readiness

Can AI crawlers actually read your site?

Before you worry about being mentioned in AI answers, make sure you can be read. CrawlX checks whether GPTBot, ClaudeBot, and PerplexityBot can fetch and render your pages, validates your llms.txt, and opens the fixes as pull requests.

The upstream half of AI visibility

What CrawlX checks before the answer engines do

Four checks that decide whether AI crawlers can read you at all — run on your whole site, in the cloud, in one pass.

AI bot access

Reads robots.txt and live responses for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended — and pinpoints exactly where any block is set, in the file or at your CDN.

llms.txt validation

Confirms your llms.txt exists, parses, and points to live URLs — so AI crawlers reach the pages you actually want surfaced instead of guessing.

Render-without-JS

Renders every page in headless Chromium and flags templates whose content only appears after JavaScript — the copy AI crawlers never see.

Robots & directive audit

Catches over-broad Disallow rules, noindex/nofollow slips, and crawl-delay settings that quietly starve AI crawlers of your content.

Honest comparison

AI-crawler access vs AI-visibility tracking

The big suites track whether you're mentioned in AI answers. CrawlX checks the thing that has to be true first — that AI crawlers can reach your content.

FAQ

AI crawlers, answered

How do I check if GPTBot can crawl my site?

Run a free CrawlX crawl on your URL. It reads your robots.txt and server responses for each major AI user-agent — GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, and Google-Extended — and tells you exactly which are allowed, which are blocked, and where the block is set.

What is llms.txt and does my site need one?

llms.txt is a plain-text file at your site root that points AI crawlers at the pages you want surfaced in AI answers. CrawlX checks whether yours exists, parses correctly, and references live URLs — and flags it if it's missing so AI crawlers fall back to guessing.

Is AI crawler readiness the same as AI visibility tracking?

No. AI visibility tools track whether your brand is mentioned in AI answers. AI crawler readiness is upstream of that — it checks whether AI crawlers can fetch and render your pages at all. If GPTBot can't read your product copy, you can't be cited for it in the first place.

Why can't AI crawlers read my JavaScript site?

Most AI crawlers fetch your raw HTML and do not execute JavaScript the way a browser does. If your key content only assembles client-side, it's invisible to them. CrawlX renders each page in headless Chromium and flags templates whose content only appears after JS runs.

Can CrawlX fix the issues it finds?

Yes. For fixable issues — robots.txt directives, missing llms.txt, meta and canonical problems — CrawlX drafts the change and opens it as a pull request on GitHub for you to review and merge. It never pushes to your default branch.
