Keyword density is the percentage of times a word or phrase appears relative to the total word count on a page. It helps you confirm a page is clearly about its target topic without overusing any single term. Google does not reward a specific density number, but a very high density (a single term making up more than roughly 4 to 5 percent of the page) is a classic spam signal worth checking.

There is no magic number. Modern SEO favors natural language over hitting a target percentage. As a loose guideline, your primary term often lands between 0.5 and 2.5 percent on a well-written page. Treat density as a sanity check, not a goal: if your main keyword appears far less than related terms, the page may lack focus; if it appears far more, it may read as stuffed.

We fetch the page, strip out scripts, styles, and HTML tags, then count visible text words. For each term we divide its occurrences by the total word count and show it as a percentage. We report single words plus the most common two-word and three-word phrases (bigrams and trigrams) so you can see real phrases, not just isolated words.

Single-word results filter out stop words (the, and, of, to, a, and similar) because they appear on every page and tell you nothing about the topic. Phrase results keep stop words inside the phrase so multi-word terms like 'project management software' stay intact and readable.

If any single word exceeds about 4 percent of total words, or any phrase exceeds about 2.5 percent, we flag it as potentially over-optimized. That usually means a term is repeated unnaturally. Rework those sentences with synonyms and related phrasing so the page reads naturally to humans first.

As a ranking lever, no. Search engines use semantic understanding, not raw counts. As a diagnostic, yes. Density quickly reveals two real problems: a page that has drifted off-topic (your keyword barely appears) and a page that reads as spammy (one term dominates). Both are worth fixing for users and for AI search engines that summarize content.

This tool measures the full visible text of the page, including navigation and footer text, because that is what crawlers parse. If your navigation or footer is large and templated, it can dilute the density of your real content. If that happens, focus on whether your target term still shows up clearly in the top phrases.
