What is the Keyword Density Checker?

Keyword density is how often a word or phrase appears compared with the total number of words on a page. This checker extracts the visible text from a URL — or text you paste — removes common stop words, and lists the most frequent keywords and phrases with their counts and percentages.

Why it matters for SEO

Search engines work out a page’s topic from the words it uses. If your target keyword barely appears, the page may not be seen as relevant; if it is repeated unnaturally, it reads as spam and can hurt both rankings and readers’ trust. Density analysis shows you, at a glance, whether the page is actually optimised for the phrase you want to rank for.

How to read your Keyword Density Checker results

Look at the top phrases: they should describe your topic. If the leading terms are navigation words, brand names or boilerplate, the main content is too thin. There is no magic percentage — natural writing usually lands around 0.5–2% for the main keyword. Anything far higher is worth rewriting.

Expert tips

Optimise for topics, not exact repetition — use synonyms and related terms.
Check competitor pages that rank on page one and compare their top phrases with yours.
Use the LSI / Related Keywords tool to find supporting terms to add naturally.
Paste a draft before publishing to catch stuffing early.

Limitations

Checks only the single URL you enter, as our server fetches it. It does not crawl the whole site, run JavaScript, or see pages behind a login.
