Because a score rewards length and keyword density. Pages get longer to satisfy it, readers get less, and the number goes up while the page gets worse.
Content analysis compares a page against the cluster it should answer and lists what is missing.
It reads the queries reaching the page, checks which are addressed, and returns the unanswered ones in the original wording — plus what higher-ranking pages cover that this does not.
A migration page never says what happens to existing data, and forty impressions a week ask exactly that. That sentence is the brief.
It will not write or rewrite the page. And it will not produce a score, deliberately, because a score is what teams optimise instead of the content.
The cluster, the page's search data, and the content of pages currently ranking above it.
It reports structure and length as facts, without scoring them.
Yes, the ones you name.
Yes, on the next crawl, against the same cluster.
