Fixes, biggest first
Add structured data (JSON-LD)
Machine-readable facts about your business: name, logo, what you sell. AI systems use it to describe you accurately.
Add real copy to the page
Readable text is a tiny share of the page's code, or there's very little of it. Crawlers summarise words, not markup.
Describe your organisation in JSON-LD
Organization or WebSite objects tie your site to a known entity, so answers name you correctly.
Offer a machine-readable interface
A valid /openapi.json or /llms-full.txt lets AI agents use your product or read your docs in full, not just your homepage.
Add an llms.txt file
A short Markdown summary of your site at /llms.txt. Cheap to add, but few AI systems request it yet, so it's worth 3 points.
Add a meta description
A one-sentence summary that crawlers and link previews reuse.
Mirror llms.txt at /.well-known/llms.txt
Some tools look in the .well-known folder instead. A copy of the same file covers both.
