What is measured
The audit normalises title text and flags a missing, very short or excessively long value.
Structure and on-page signals
Page title
This check assesses the presence and approximate length of the HTML title used by browsers and search results.
Pass criterion
Every page has a specific title that matches its content and differs from neighbouring pages.
What to fix
Write the title around the page’s real task, add distinguishing context and remove repeated generic wording.
Automation limit
A search engine may rewrite the displayed title when another page fragment appears more useful.
