- What llms.txt is, and which AI crawlers actually asked for mine in the domain's first 16 days of server logs.
- Core Web Vitals — and the measurement of mine that turned out to be worthless, and why.
These are free and they stay free. If after reading one you want the same thing done on your site, the free diagnostic is the next step. It's read-only, in writing, with its pending items.
