Keyword Density Checker - results and guide

What the Keyword Density Checker checks

  • Total and unique words in the main content
  • The most frequent single words, with count and density
  • The most frequent two-word and three-word phrases
  • A warning when one word dominates the text
  • Optional: count and density of your target keyword
  • Optional: whether the keyword is in the title, description, H1, URL and first 100 words

What is keyword density?

Keyword density is the share of a page's words taken up by one word or phrase. If a term appears 10 times in 500 words, its density is 2%. The figure was once treated as a target. Today it is useful as a diagnostic: it shows what a page is really about, and whether a term is used so often that the text reads badly.

This tool counts words in the main content only. Navigation, header, footer and forms are left out, and common words such as "the" and "and" are not ranked.

Is there an ideal keyword density?

No. Google has said plainly that it has no ideal percentage. Search engines look at meaning: related terms, synonyms and whether the page covers the topic. Repeating one phrase to reach a number is keyword stuffing, which Google's spam policies describe as a reason to rank a page lower.

As a rule of thumb, natural writing keeps a main term under about 3 to 4%. More useful than the percentage is placement: use the phrase once in the title, the H1 and the opening paragraph, then write for the reader. The two- and three-word tables show the phrases your page actually emphasises, which is often a surprise.

How to use the Keyword Density Checker

  1. Enter the address of the page you want to check. You can leave out https://.
  2. Optionally add the keyword you want the page to rank for.
  3. Press Analyse text. The page is fetched from our servers, the way a search engine crawler would fetch it.
  4. Read the findings from top to bottom: problems first, then warnings. Each one says what to change.

Common problems and how to fix them

A single word is far above the rest

Read the passage aloud. Replace repeats with synonyms, pronouns or more specific terms, and cut sentences that exist only to mention the keyword.

The target keyword does not appear at all

The page may be about something slightly different from what you intended. Rewrite the title, H1 and introduction around the phrase people search for.

Very few words were analysed

The text may be loaded by JavaScript or sit inside elements treated as navigation. The tool reads the HTML that the server returns.

Frequently asked questions

What is a good keyword density?
There is no official figure. Text that reads naturally usually has its main term at 1 to 3%. Above about 4% it starts to look forced.
How is keyword density calculated?
Occurrences of the term divided by the total number of words, times 100. For a phrase, each occurrence counts once for every word in it.
Does keyword density still matter for SEO?
Not as a target. It is helpful for spotting keyword stuffing and for checking that a page is focused on the topic you intend.
Which words are ignored?
Very common English words such as the, and, of and to. They appear in every text and say nothing about the topic.
