How it works
- Paste your content — any article, product description or page text. A live word counter keeps track as you type.
- Tune the analysis — pick a preset, set reading speed and minimum word length, and toggle the stopword filter and case sensitivity.
- Analyze — the tool counts every 1-, 2- and 3-word phrase, shows density percentages, and flags anything at 3% or higher as possible keyword stuffing.
Everything runs in your browser — your text never leaves this page.
Everyday uses
- Bloggers — check each post stays in the natural 1–2% range before publishing.
- Copywriters — prove to clients the copy is optimized without being stuffed.
- Students — spot overused words and phrases in essays before submitting.
- SEO freelancers — audit client content and back your recommendations with numbers.
- Content teams — set a house standard (e.g. “nothing above 2.5%”) and enforce it in seconds.
Rule of thumb: 1–2% density for your main keyword reads naturally to both people and search engines. If one phrase hits 3%+, rewrite — Google rewards natural language, not repetition.
