Fixes, biggest first
Put your words in the HTML
A crawler that runs no JavaScript found under 400 characters of text. Whatever your page says after scripts run, it doesn't say to them.
Stop serving an empty app shell
The page is a JavaScript shell: scripts plus almost no text. To most AI crawlers it looks blank.
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 canonical link
Tells crawlers which URL is the real one when the same page is reachable at several.
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.
