What these tools will not tell you
Every metric here is a diagnostic, not a target. Keyword density has not been a positive ranking signal for over a decade; word count has never been one. What they are good for is catching problems: a term repeated to the point of awkwardness, a title that will be cut mid-word, a page that does not mention its own subject.
The things that actually decide rankings for a tool site: page speed, whether the tool works, whether anyone links to it — are not measurable in a text box.
