Robots and AI Crawler Checker
Paste robots.txt and page head markup to find full-site crawler blocks, noindex directives, missing canonical tags, and sitemap discovery gaps.
Direct answer
A robots and AI crawler checker reviews whether public SaaS pages are discoverable by search and answer engines. It flags full-site blocks for major crawlers, noindex directives, missing canonical tags, and sitemap signals that can reduce retrieval clarity.
Why crawler access matters
AI answer systems can only cite or summarize public information they can retrieve through search indexes, partner indexes, or live web access. A blocked product page may still be useful to users, but it is a weak citation candidate.
What to paste into the checker
Paste the relevant robots.txt content and the head markup from the page you want discovered. The tool checks for full-site Disallow rules, noindex, canonical links, and sitemap discovery signals.
What this tool cannot do
This static checker does not crawl your site from a server. It is designed for fast local review without sending your page source to a third-party API.

FAQ
Does allowing AI crawlers guarantee citations?
No. It only removes one technical blocker. Content quality, authority, and relevance still matter.
Should every AI crawler be allowed?
That is a business decision. Public marketing pages usually need discovery, while private app pages should stay blocked.
Why does canonical matter for GEO?
Canonical tags reduce duplicate URL ambiguity and help systems choose the intended source page.
