Keyword Density Checker: Complete Usage Guide
Audit a draft in five minutes — spot dilution, over-optimisation and off-topic drift before publishing.
Open the toolPurpose
This tool counts how often each word and phrase appears in your text and shows the percentage share of the document. Density is no longer a ranking lever, but it is an excellent diagnostic: it catches drafts that never clearly state their subject, and drafts that repeat one exact phrase so often they read as spam. Use it as the last editorial pass before you publish, not as a target to write toward.
How to use it
- 1Paste your draft into the text area.
- 2Enable stop-word filtering so 'the' and 'and' do not dominate the results.
- 3Read the top ten terms. If a stranger saw only that list, would they guess your topic?
- 4Find your primary keyword and check its percentage — 0.5% to 2.5% is the healthy band.
- 5Review the two- and three-word phrases to see whether you are covering subtopics or circling one idea.
Tips & tricks
- Placement beats frequency: title, H1, first 100 words, one or two subheadings, alt text and the URL slug.
- Vary your vocabulary. Comprehensive coverage naturally introduces related terms; forced repetition does not.
- Read the page aloud after editing. Anything that sounds repetitive out loud is repetitive.
- Shorter pages naturally show higher density. Judge the range against the length.
- Pair with the SEO Word Counter for length and the Meta Tag Generator for the head block.
Common errors and fixes
My keyword is not in the top terms at all
The page is unfocused. Work the term into the title, opening paragraph and one subheading, phrased naturally.
Density is above 3%
Replace some occurrences with synonyms and pronouns. Over-optimised copy reads badly and can trigger spam signals.
Two-word phrases show odd fragments
That is normal for phrase analysis across sentence boundaries. Focus on the phrases that appear repeatedly within paragraphs.
