I scored the 50,074 most-visited websites for how readable they are to AI agents. Not one scored "excellent." The median site is a 52 out of 100. Here is what the web looks like to an agent.

Publishing an llms.txt is now nearly free, and adoption is climbing. Getting an agent to actually read it is the hard part. We benchmarked both sides. There's good news and bad news.
Full benchmark on a14y.dev/research, and I'm sending these first on Substack: substack.com/@EngAndArt

The web has SEO-era plumbing but has not built the agent-era layer yet. The full reports and the leaderboard are live. I would love to hear what you find on your own sites. a14y.dev/research/

Paul is a gem of a person whom I had the great luck to work with at Google. Even if Impeccable wasn't amazing, I'd say this venture was a good bet. But Impeccable is amazing. It's one of just four must-have tools for every one of my projects. If you haven't checked it out yet, you really should. It will make your work better.
Congrats on the launch, @pbakaus ! I'm really looking forward to what you publish next and where you take Impeccable.
AI raised the floor. Time to raise the ceiling.
Today I’m launching Renaissance Geek, the company behind Impeccable, backed by @a16z (led by @illscience), and a first partnership with @github .
Here’s the bet I’m making 👇

Everyone selling "AEO" slot content right now is reinventing the link farm. We've seen this movie before, when webmasters tried to cheat PageRank. We know how it ends.

Google already says ignore "inauthentic brand mentions" and that AI optimization is still just SEO. The durable play is the one SEO landed on: be agent-readable, then actually be the best. Everything else is borrowing visibility from a future penalty. Full piece below.
