Count the top words and two- and three-word phrases on a page or in your text, with their density, to spot a missing topic or over-repetition.
How to use the Keyword density checker
- Paste text or enter a URL.
- Read the top words and phrases with their density.
- Make sure your main topic shows up naturally, and cut obvious repetition.
There is no ideal density
Google doesn't reward a target percentage. Use density to check that your page actually covers the topic you want to rank for, and that you haven't repeated one phrase unnaturally.
Reading the tables
Density is how often a word appears divided by the total word count. The keywords table shows the top 25 single words; anything over 3% turns red, which on a normal page often reads as forced. The phrase panels show two- and three-word phrases that appear more than once, which is usually where your real topic shows up. The stats row gives total words, unique words, the top keyword with its density, and the top phrase with its count. In URL mode the page's visible body text is analysed, so navigation and footer words can appear.
What to change
If your main keyword isn't in the top words at all, the page probably doesn't explain the topic clearly; add it to the title, H1 and first paragraph. If one word is far above everything else, replace some uses with pronouns or related terms. If the top phrases are menu items like "sign up" or "privacy policy", the page has little real content around the topic. Compare with a page that ranks for your keyword to see which related words it covers that yours doesn't.
