Keyword Density Checker
Analyze keyword density and keyword frequency in your content for SEO optimization.
About Keyword Density Checker
Paste any content to see keyword frequency, density percentage, and the top 20 keywords by usage. Target a specific keyword to check its density score.
About this calculator
Paste your content and a target keyword, and the checker reports how often it appears and the percentage of words it represents, along with the most frequent words on the page. It is a quick guard against both under-use and stuffing.
Run it on a draft before you publish.
How to use it
- Paste the content.
- Enter the target keyword (optional).
- Press Analyze.
Formula
Keyword density = occurrences of the keyword ÷ total words × 100. For a phrase, each occurrence of the full phrase counts once. There is no official 'ideal' density: search engines read meaning, not percentages. A natural range is about 0.5% to 2%, and anything higher usually reads as stuffing.
Worked example
'seo tips for seo and content seo' (7 words)
| seo | 3 times = 42.9% |
That is far above any natural range. It shows how a very short text can mislead; use long drafts for meaningful density.
Tips and common mistakes
- Write for people first. Use the keyword where it fits naturally.
- Use synonyms and related terms rather than repeating one phrase.
- Put the main keyword in the title, first paragraph and a heading.
- Stuffing the keyword can hurt rankings and reads badly.
- Check the top-ranking pages for the typical use of your terms.
