Partly builtDepth, duplicates and freshness, checked on every page

Content audit

Whether a page actually answers the question it appears to promise, read from the copy your site served rather than from a keyword count.

What runs

Content depth, semantic keyword coverage, topic clusters, readability scoring, duplicate detection via content fingerprinting, and freshness.

What the catalogue adds

Keyword research, search intent, pillar pages and gap analysis each have a page in the check catalogue explaining what they read and what they need to run. You are never billed for a check that did not run, and none of them is counted in your plan until it does.

The checks behind this

14 of 15 running. Each has its own page.

Questions

Can I see what each check reads before I buy?

Yes. Every check has a page in the catalogue saying what it inspects, why it matters, and what it needs. You can read the whole thing without an account, and you are only ever billed for checks that ran.
