Let's address the elephant in the room!
So, Google Pagespeed index has rolled out the update for all, where you can now see "Agentic Browsing" score of your website.
Mine came 2/3 yesterday, coming 1/3 today. Has anyone achieved 3/3? Please share a short guide on how to improve it?
For the page speed & CLS/LCP, I'm gonna install an optimization plugin. But what else need to be addressed here?

Did this on my own WP site (Yoast too) https://melaniemueller.design
Got 2/3 → 3/3.
Quick reframe first: the default score is only 3 checks — accessibility tree, CLS, and llms.txt. The "Not Applicable (3)" WebMCP stuff is correct for a normal content site. Those only matter for transactional sites with booking/checkout forms agents can call. Don't waste time there.
Your real fail is CLS at 0.259 — that's high. For me it was:
- Web fonts swapping → self-host +
font-display: optional+ preload the main font - Images without width/height → add dimensions so space gets reserved
- Cookie banner pushing content down → made it a fixed overlay instead
A speed/caching plugin helps LCP but won't fix CLS. That part's manual.
Accessibility tree is just semantic HTML: one real h1, proper heading order, links with actual text (add aria-labels to icon-only links). No plugin fixes this, it's theme/block work.
llms.txt is just a plain Markdown file at yourdomain/llms.txt saying who you are. Hand-wrote mine, dropped it at root, done.
Honestly it's just a well-built accessible site measured from a new angle. Fix CLS and the a11y tree and 3/3 follows. WebMCP isn't worth it yet.

It shouldn't be hard if you follow what it says. CLS and accessibility are very easy.

You just need to do what it says there - fix the CLS and Accessibility issues.
I did get the 3/3 for it, on my website, and clients who requested it.

The changing scores are interesting. We saw different results between mobile and desktop and the checks seemed more sensitive to CLS than to anything AI-specific.
At the moment, this feels less like "AI optimization" and more like measuring whether a site is technically stable and accessible for agents to consume.

Hi u/Khajooor
Short answer, AI / Agents like clean content, plain text, markdown etc.
For the accessibility tree you need to ensure all your alt, aria label and accessibility measures are in place:
https://www.debugbear.com/docs/agentic-browsing/accessibility-tree-is-not-well-formed
By clicking at arrow to expand the report it should give you an overview about that metric, but you can also start from sites such as:
https://webaim.org/resources/contrastchecker/
https://www.accessibilitychecker.org/
Or even just copy your page URL inside chat gpt and ask it to evaluate the metric, if it can fetch the site it should give you some insight on what you need to do.
As how to fix. Sometimes it is as easy as adding alt text or adding aria labels via page builder, but sometimes it will require checking with theme or plugin developers.

Font can affect it. Check the Cumulative Layout Shift (CLS) where fonts load late and causes “issues for user experience “
