Check
A unique, complete title and description
A unique, complete title and description is check B1 in the fifteen-point audit. Each page states its own subject in the title and description, and both agree with the visible heading.
What counts as evidence
The title, meta description and h1 we parsed from the raw HTML.
How to fix it
Give every page a title that names the subject and a description that answers what it is for. Do not reuse the site tagline.
Where this sits
B is the group: accessibility, comprehension, or extractability. The groups run in order — a crawler that cannot reach the page never reaches the reading checks — so fix the earliest failing group first. The full definition of all fifteen items is in the standard.
