Calculate keyword density and check it against natural-language norms.
Keyword density is a diagnostic rather than a target. Modern search engines use semantic matching, so anything above about 3 per cent reads as manipulation without improving relevance. Writing naturally about a topic produces appropriate density automatically; optimising the number directly is what produces unreadable copy.
