llms.txt was the laughing stock of SEO community for a year because nothing crawled it. That changed this month. Requests are up 10x across @SitelineAI, 52% from Anthropic. Agents are using it as a table of contents, picking 2-3 doc pages from the index. If you're docs-heavy, make yours a clean index.

What used to be "link building" is now about getting your brand mentioned with the right context to portray your product's strengths. We just shipped this in @SitelineAI: find publishers AI already cites in your category, place your brand, and track if it gets picked up.

85% (11/13 articles) of NYT homepage is Trump related. Obviously topical, but isn't there else going on in the world worth knowing?
