Keyword Density Checker

Find the most frequent words and phrases in your text or page HTML, with counts and density, and check a target keyword.

Keyword density is the share of a page's words taken up by a particular word or phrase. Checking it shows what a text is really about — the terms a reader or search engine sees most — and helps you find gaps and overuse. If your article targets coffee grinders but grinder barely appears while beans dominates, the page may not match what people search for; if one phrase appears in every other sentence, it reads as spam.

Paste the text of an article or the HTML source of a page. The checker lists the top single words, two-word and three-word phrases with their count and density, ignoring common words like the and of. Enter a target keyword to see its density and whether it appears in the title, the main heading and the first paragraph. Nothing is uploaded or fetched — the analysis happens in your browser.

How to use Keyword Density Checker

  1. Paste the text or HTML source of your page, or press Sample.
  2. Optionally enter the keyword you are targeting.
  3. Choose whether to ignore common words.
  4. Review the top words and phrases and the keyword's density and placement.

How density is calculated

Density is the number of times a word or phrase appears, multiplied by the number of words in the phrase, divided by the total number of words, as a percentage. A two-word phrase that appears 5 times in a 500-word article covers 10 of its words, a density of 2%. Words are compared without regard to capitals, and a possessive 's is ignored, so Coffee, coffee and coffee's count together.

DensityUsually means
under 0.5%The term is barely mentioned
about 0.5–2%A natural level for a main keyword
about 2–3%Prominent; check it still reads naturally
over 3%Probably repetitive — vary the wording

There is no perfect density

Search engines have not used a target keyword density for many years. Modern ranking systems understand synonyms, related terms and the topic of a page as a whole, and repeating a keyword unnaturally — keyword stuffing — can hurt rankings. Use density as a diagnostic: confirm that your main topic is clearly present, that the phrases you see most are the ones you intended, and that no single phrase is overused. Write for readers first; aim to answer their question completely in natural language.

Where the keyword appears matters

Placement often matters more than count. Including the main keyword or a close variant in the page title, the main heading (H1), the first paragraph, at least one subheading and the meta description helps both readers and search engines understand the page quickly. When you paste a page's HTML, the checker reports whether the target keyword appears in the title, the H1 and the first paragraph, and ignores scripts, styles and other code so only visible text is counted.

Getting the page text

To check a published page, open it in your browser, select all the text and paste it, or use View page source and paste the HTML to include the title and headings. Text from navigation menus, footers and cookie banners is included when you paste the full HTML, which can slightly inflate common terms; paste just the article for the cleanest result. Use the Readability Checker on the same text to make sure it is easy to read, and the Meta Tag Generator to write the title and description.
