Keyword Density Checker

Keyword density is the percentage of times a target keyword appears relative to the total word count on a page. While no longer the dominant ranking signal it was in the early 2000s, it still provides a useful diagnostic for content that may be over- or under-optimized for a target term.

• Modern search engines use natural language processing — they understand synonyms and related terms, so variety matters more than exact repetition.
• Keyword prominence (placement in title, first paragraph, and subheadings) often matters more than raw frequency.
• Always check density for both your primary keyword and its closest semantic variants to avoid unintentional keyword cannibalization.

If your density check reveals over-optimization, the solution is not simply deleting keyword occurrences — it is replacing them with semantically equivalent phrases. This maintains topical relevance while making the text sound natural.

• Replace repeated exact-match phrases with LSI keywords, pronouns, or topic-related synonyms.
• Break up dense keyword passages with supporting facts, quotes, or examples that enrich content depth.
• Re-read the content aloud — if it sounds robotic or repetitive, it likely needs editing regardless of the density number.
