AI Search Readiness Audit

Check whether ChatGPT, Perplexity, Claude, and AI Overviews can see and cite your site, plus a real llms.txt generator.

We fetch robots.txt, the page itself, and llms.txt live on every run - nothing here is cached or simulated.

AI crawler + llms.txt auditorLive fetch

How it works

1

Enter your URL

One page or your homepage. No account or API key needed to run the audit.

2

We fetch robots.txt, the page, and llms.txt live

Three real requests run in parallel: robots.txt for AI-crawler rules, the page itself for structured data and meta signals, and llms.txt at your domain root if one exists.

3

Read the 4-category report

AI crawler accessibility, structured data validity, meta/entity signals, and llms.txt status - each broken down into individual pass/fail checks.

4

Generate a real llms.txt

Crawl your sitemap.xml, verify every page is actually reachable, edit titles and sections, then copy or download the finished file.

Questions

All 17 this app tracks: OpenAI's GPTBot, ChatGPT-User and OAI-SearchBot; Anthropic's ClaudeBot, Claude-Web and anthropic-ai; Perplexity's PerplexityBot and Perplexity-User; Google's Google-Extended and GoogleOther; Common Crawl's CCBot; ByteDance's Bytespider; Amazon's Amazonbot; Apple's Applebot-Extended; Meta's Meta-ExternalAgent; and DuckDuckGo's DuckAssistBot.

Whether your robots.txt disallows that bot's user-agent token at the site root - the same rule a real crawler checks before it requests any page.

No. Titles and descriptions are pulled directly from each page's own <title> and meta description tags - nothing is generated by an LLM unless you've connected your own API key elsewhere in SerpCrest.

Yes - once you build a draft you get both a Copy button and a Download llms.txt button for the finished, plain-text file.

Yes: up to 10 audits per minute, and up to 3 llms.txt sitemap-generation requests per minute since that one can crawl 100+ pages from your sitemap.

Rarely, so far: most llms.txt files get no AI traffic at all, per our look at llms.txt adoption. Crawler access matters more, including links that AI crawlers cannot see because they only appear after JavaScript runs.
