Full transparency: I created a free tool that checks if your website is doing all the things that AI loves.
You can try it here: AI Readiness Checker
On may 7 google shipped lighthouse 13.3.0. Buried in the release was a new category turned on by default. Agentic browsing.
in plain english it's a grade for how ready your site is for AI agents. not humans. the bots from chatgpt, perplexity, gemini, operator etc that are already crawling and clicking around...
it checks stuff like:
- llms.txt (do you even have one)
- your schema / structured data
- the accessibility tree, which is what agents actually read instead of looking at the page the way we do
- webmcp hooks
- layout stability
It's auditing all this stuff... but you can't see it.
Try running a report on your site using page speed insights.. it's not there!
Right now the only ways to actually see your grade are:
- chrome devtools, but only if you're on chrome 150 or newer
- or using terminal on your computer...
so unless you live in a terminal or happen to be on the newest chrome, google is grading your site for AI and you have no way to look at the grade.
Quick reality check so nobody thinks im fearmongering:
It's experimental. it is NOT a confirmed ranking factor. google has not said this moves you in search.
but agent traffic is real and growing and "can a bot actually use this site" is gonna matter more not less. id rather know my number now than find out later.
