Definition
An AI sitemap is a machine-readable map of the site that focuses on semantic value rather than only URL discovery.
It can include content types, topic relationships, glossary sets, directory collections, and public endpoint files.
In Practice
This can live alongside a traditional XML sitemap. The XML sitemap helps standard crawlers. The AI sitemap can add richer context about the site's architecture.
It should emphasize what the site wants understood first.
Worth Knowing
Do not confuse a richer JSON AI sitemap with a replacement for XML. Both can be useful.
A sitemap that lists everything but prioritizes nothing is less helpful.
