About Keyword Density Checker
Paste your content to see which words and phrases occur most frequently, with counts and percentages for single words and multi-word phrases.
It is worth being direct about what this measures. Keyword density is not a ranking factor and has not been one for a long time. Search engines moved to semantic understanding years ago โ they evaluate whether a page genuinely covers a topic, not whether a phrase hits a percentage target. Any advice recommending a specific density figure such as 2% is obsolete, and writing to hit it produces worse content.
The genuinely useful application is diagnostic, and it runs in both directions. If your target term appears once in two thousand words, the page may not actually be about what you intended โ that is worth knowing. And if it appears forty times, the writing has probably become repetitive in a way that reads badly to humans and looks like keyword stuffing to a search engine, which is a real quality signal and can be penalised.
Pay more attention to the phrase counts than the single-word counts. Related terms and natural variations are what demonstrate genuine topical coverage: a page about running shoes that never mentions cushioning, pronation, or midsole is thin on the subject regardless of how often the exact phrase appears. Use this to check that your writing covers the topic, then trust the writing.
How to use Keyword Density Checker
- Paste your article or page copy.
- Review the most frequent words and phrases with their counts and percentages.
- Check your main topic actually appears, and that nothing is repeated so often it reads badly.
Frequently asked questions
What keyword density should I aim for?
None. Density is not a ranking factor and targeting a percentage produces worse writing. Use the numbers to confirm your topic is genuinely covered and that nothing is repeated to the point of reading badly.
Can keyword stuffing hurt my rankings?
Yes. Unnaturally repeated phrases are a recognised spam signal and can trigger a penalty. It also makes content unpleasant to read, which affects the engagement signals search engines do measure.
What should I look at instead of density?
Topical coverage โ whether the related concepts a knowledgeable reader would expect are present. A page about running shoes that never mentions cushioning or pronation is thin on the subject however often the main phrase appears.
Is my text uploaded?
No. The analysis runs entirely in your browser, so unpublished drafts stay on your device.
