Google's Lighthouse tool now includes an audit specifically for AI agent discoverability, which means there's a testable standard for whether your site is structured in a way AI systems can actually read and use. If your writing and profiles live on a domain you own, running this audit tells you whether AI search can actually see you.
Quick background: Lighthouse is a free tool from Google that audits a web page and scores it 0 to 100 in four areas: performance, accessibility, best practices, and SEO. Web developers have used it for years to find what's slowing a site down or making it hard to use. The new part is a fifth category, Agentic Browsing, which checks whether AI agents can find and use what's on your site.
Want to check your own site? You don't need to install anything. Go to PageSpeed Insights, paste in your website address, and click Analyze. It runs Lighthouse for you and shows the scores for both mobile and desktop. Mobile scores usually come in lower because the test simulates a slower phone connection. If it says "No Data" for real-user results, that's normal for smaller sites.
Here's what it looks like in practice. I ran my own site, which is hosted on publish.law, through PageSpeed Insights on the mobile test, the harder of the two. It scored 99 for performance, 100 for accessibility, best practices, and SEO, and passed all 3 of the new Agentic Browsing checks. You don't need a big web budget to get there. You need a site that's built right from the start.
