What is measured
The audit normalises case and calculates the share of unique values within the checked sample.
Structure and on-page signals
Unique page titles
This check compares titles across the sampled pages and finds repeated wording.
Pass criterion
Every standalone page has its own title, while duplicate pages are consolidated by redirects or canonical signals.
What to fix
Separate page tasks, rewrite template titles and eliminate technical URL duplicates.
Automation limit
A unique title does not justify a separate page that lacks its own useful content.
