Paste any article, blog post or landing-page copy and see in seconds which words you're using most often, what their density percentage is, and whether you're accidentally over-optimising for a single phrase.
Keyword density is the percentage of times a specific word or phrase appears in a piece of content relative to the total word count. It used to be the headline metric for on-page SEO; today, search engines focus on topical relevance and reader intent, but density is still a useful sanity check. If your target keyword is buried under filler words, your topical signal is weak. If it appears in 8% of your sentences, you risk looking spammy.
The tool tokenises your text into individual words, removes English stop-words like 'the' and 'and', counts how often each remaining word appears, and divides by total word count to produce a density percentage. The top 25 keywords are sorted from most to least frequent so you can see the actual topic profile of your page at a glance — ignoring noise.
Run it before you publish a new blog post, after a content refresh, when an old page suddenly drops in rankings, or while writing meta descriptions and headings. Editors and SEO strategists use it to quickly audit a competitor's article and reverse-engineer their keyword targeting.
Aim for a primary keyword density of roughly 1–2% — enough to signal relevance, low enough to read naturally. Pay more attention to semantic siblings of your target keyword in the top 10 list (synonyms and related terms) than to the headline density number itself; modern Google rewards topical depth, not exact-match repetition.
There's no magic number. 1–2% for your primary keyword is a safe ballpark for blog content. If your top keyword exceeds 4–5% it usually reads as spammy to humans and search engines alike.
No. Common English stop-words like 'the', 'a', 'is', 'and' are filtered out so the top results reflect the actual topic of the piece.
No. Density is a diagnostic, not a target. Write for the reader first, then sanity-check that your topic words are present without being repetitive.
