Crawlability is how easily automated crawlers — including AI crawlers like GPTBot, PerplexityBot, and Google’s — can access, read, and understand your pages. If a crawler can’t reach or parse a page, retrieval-based AI engines effectively can’t see it.
Why it matters for AEO
Crawlability is a prerequisite for AI visibility on retrieval-based engines. The best content in the world earns zero citations if engines can’t fetch it. Common crawlability problems quietly remove brands from AI answers:
robots.txtrules that block AI crawlers (sometimes added unintentionally).- Content rendered only via JavaScript that crawlers don’t execute.
- Slow pages or errors that cause crawlers to give up.
- Important text locked in images or PDFs rather than crawlable HTML.
What to check
Confirm your robots.txt allows the AI crawlers you want, ensure key content is in server-rendered HTML, keep pages fast, and verify there are no blocking errors. See AI crawlers guide and the related concept of indexability.
