What it is
The title is the single most important on-page tag. It is what shows in results, what AI systems lean on to understand the page, and a confirmed ranking factor. A page with no title is throwing that away. No title element.
Why does missing <title> matter for AI search?
Titles are a primary relevance and click signal and are processed during indexing; absence severely weakens the page.

- View source and check for a title element in the head.
