Density is the share of all terms of that length. Rows above 3% are flagged — worth a re-read to check they still sound natural.

About this tool

What a keyword density checker is actually for

Keyword density is simply how often a word or phrase shows up in your content, expressed as a percentage of the total word count. Google doesn't rank pages on a magic density number — there's no secret 2% target that guarantees a ranking — but wildly repeating the same phrase is still a real, visible signal of keyword stuffing, both to search engines and to human readers. This tool pastes your content, breaks it into single words, two-word phrases, and three-word phrases, and shows you the frequency and density of each one so you can spot over-repetition before you publish, not after.

How to use it

  • Paste your article, product page, or blog post content into the box.
  • Optionally enter your primary focus keyword or keyword phrase — you'll get a dedicated density score and a plain-language rating (too low, healthy, or stuffed) instead of having to hunt for it in the tables.
  • Leave "Exclude common stop words" checked to filter out words like "the," "and," and "is" from the single-word list, since those will always dominate raw frequency counts without saying anything useful about your content's focus.
  • Click Analyze to see your top single-word terms plus your top 2-word and 3-word phrases (bigrams and trigrams), each with a count and density percentage. Rows flagged with a warning icon are above a 3% density — a common informal threshold where repetition starts looking unnatural.

What counts as "good" keyword density?

Most SEO practitioners treat roughly 1-2% as a reasonable density range for a primary keyword phrase in long-form content — enough that the topic is clearly the subject of the page, not so much that it reads like it was written for a bot instead of a person. There's no official Google-published target, so treat any density number, including this tool's, as a sanity check rather than a rule to hit exactly.

Real-world use cases

  • Pre-publish content review: Catch a phrase you unintentionally repeated 15 times before it goes live and looks spammy to readers.
  • Competitor content analysis: Paste a competing page's copy in to see roughly how often they use their target keyword and related phrases.
  • Content briefs for writers: Check a draft against the intended focus keyword to confirm the topic is actually covered at a reasonable frequency, not just mentioned once in the title.
  • Spotting thin or repetitive filler: A high density on a phrase that isn't your actual target keyword often points to filler text or a stuck writing pattern worth editing out.

Frequently asked questions

Does keyword density directly affect Google rankings?

Not as a standalone ranking factor in the way it did in the early 2000s. Modern search engines use much more sophisticated language understanding, so unnatural repetition is more likely to hurt readability (and trigger spam-style over-optimization signals) than to help rankings on its own.

Why are my top single-word results full of generic words like "content" or "page"?

Turn on "Exclude common stop words" if it isn't already — it filters function words (the, and, of, etc.), but genuinely common topic words in your niche will still show up, which is expected and useful.

What's the difference between the single-word, 2-word, and 3-word tables?

Single words show individual term frequency; 2-word (bigram) and 3-word (trigram) phrases show how often exact multi-word phrases repeat, which is often more useful for judging natural-sounding keyword usage than single-word counts alone, since most real target keywords are phrases, not single words.

Should I aim for an exact density percentage?

No — write for the reader first, then use this tool as a sanity check afterward. If a phrase's density is well above everything else on the page (and above roughly 3%), that's worth a second read to see if it reads naturally or feels forced.
