Keyword density is useful, but only when you use it like a signal, not like a target to worship. Over-optimizing content makes it weaker, not stronger.
What the checker is actually for
A keyword density checker helps you see whether a target term is missing, overused, or distributed poorly across the page.
What it should not do
It should not convince you to stuff the same phrase into every sentence. Google does not reward robotic repetition. Readers hate it too.
Best workflow
- Write naturally first
- Check whether the main term appears in key places
- Use related phrases where they fit
- Revise for clarity, not just density
