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.
Publish a sitemap.xml
A list of every page you want found. Without one, crawlers only find what's linked.
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.
Keep sitemap dates fresh
No lastmod date in the last 90 days, so crawlers can't tell what changed and may not come back.
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.
