Can ChatGPT actually read your site?
One fetch of your robots.txt, parsed the way the bots parse it. Nine AI crawlers, each one told apart by whether blocking it costs you visibility today or just training data.
Not every blocked bot is a problem
Most checkers show one red X per blocked crawler. That flags a normal licensing decision as an emergency and hides the one block that actually removes you from AI answers.
Citation isn't training
GPTBot trains OpenAI's models. ChatGPT-User is what fetches your page when someone asks a question right now. Blocking the first costs you nothing today; blocking the second removes you from the answer.
Most blocks are accidental
A wildcard Disallow written years ago for a staging site, or a security plugin's default bot list, blocks these crawlers without anyone deciding to. That's the case this tool is built to catch.
Allowing costs nothing to undo
robots.txt is advisory and instantly reversible — an Allow rule you add today can be removed tomorrow, and neither direction requires a redeploy.
What this doesn’t tell you: Reads robots.txt only — a crawler can still be blocked by your firewall, WAF, or CDN bot rules, which no robots.txt check can see.
Run all of this on your whole site, continuously
These tools check one thing once. SEO Engine watches every page, every week, and writes the fixes for you.
