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.
The page is a JavaScript shell: scripts plus almost no text. To most AI crawlers it looks blank.
Machine-readable facts about your business: name, logo, what you sell. AI systems use it to describe you accurately.
Readable text is a tiny share of the page's code, or there's very little of it. Crawlers summarise words, not markup.
One clear main heading tells a crawler what the page is about.
Tags like main, nav, article and footer show which part is content and which is chrome.
Organization or WebSite objects tie your site to a known entity, so answers name you correctly.
A valid /openapi.json or /llms-full.txt lets AI agents use your product or read your docs in full, not just your homepage.
Some tools look in the .well-known folder instead. A copy of the same file covers both.
