How to use keyword density well
Keyword density is a diagnostic, not a goal. Use it to answer two questions:
- Is the main topic actually there? If your target phrase never appears, or only in passing, the page may not clearly match what people search for.
- Is anything over-repeated? If one phrase dominates the list, the text probably reads unnaturally. Swap some uses for variations, synonyms or pronouns.
What matters more than density
- Placement: the main phrase in the title tag, H1 and first paragraph does more than extra repetitions in the body.
- Coverage: answer the related questions people have. Look at the 2- and 3-word lists for subtopics you might be missing.
- Intent: a page that matches what the searcher wants beats a page that repeats their words.
Finding the right keyword in the first place
The best target is usually a query you already get impressions for. Search Console keyword research shows which ones, and the title and meta length checker helps you put the keyword where it counts.
