The Keyword Density Analyzer shows how often each word and phrase appears in your content, as both a raw count and a percentage of the total. It highlights your most-used terms, flags possible over-optimization, and lets you analyze single words, two-word phrases and three-word phrases — so you can confirm your content is focused on the right topics without sounding stuffed or repetitive.
It is part of the SERP & Content Analysis group in our free SEO Toolkit, alongside the Word Count & Reading Time tool the Readability Scorer and the Heading Structure Checker. After analyzing, refine your titles with the SERP Snippet Preview and build your tags with the Meta Tag Generator. Everything runs in your browser — your text is never uploaded or stored.

Keyword density is the percentage of times a word or phrase appears in your content relative to the total number of words. If a 500-word page uses the phrase "keyword density" ten times, its density is 2%. This tool calculates that for every significant word and phrase in your text, helping you confirm your content is clearly about its topic without overusing any single term. It is part of the SERP & Content Analysis group.
There is no magic percentage, and Google has never published one. Modern search engines understand topics and synonyms, so writing naturally for your reader matters far more than hitting a number. As a loose guide, a primary term often sits comfortably below about 2–3%, but the real test is whether the text reads well. This tool flags very high densities not because a threshold is official, but because heavy repetition usually signals awkward, stuffed writing.
| Density Range | What It Usually Means |
|---|---|
| Under 1% | Term may be underused for a focus keyword |
| 1% – 2.5% | Typically natural and well-focused |
| 2.5% – 4% | Getting heavy — check it still reads naturally |
| Over 4% | Likely over-optimised or repetitive |
Treat these as guidance, not rules. A well-written page that mentions its topic clearly will usually land in a healthy range on its own.
Check that your main topic and related terms actually appear prominently in the text.
Spot terms repeated so often they harm readability and risk looking manipulative.
Notice important terms that barely appear and could be woven in more naturally.
Two and three-word views reveal the key phrases your content really emphasises.
Density is the keyword's count divided by the total number of words in your text, shown as a percentage. For phrases, the count is how many times that exact sequence appears. The total word count is used as the denominator so single-word and phrase densities are comparable.
Stop words are very common words like "the", "and" and "of" that appear in almost all text and carry little topical meaning. Filtering them out lets your real keywords rise to the top of the list. You can toggle this off if you want to see every word.
No. Keyword density is not a direct ranking factor, and chasing a specific percentage can make writing worse. Use this tool to sanity-check focus and catch stuffing, but always prioritise clear, helpful content written for people.
No. All analysis runs locally in your browser with JavaScript. The text you paste is never uploaded, logged or stored, so the tool is safe for drafts, unpublished pages and confidential client content.

Everything about analyzing keyword density.

There is no official ideal, and Google has never published one. Writing naturally matters most. As loose guidance, a primary term often sits below about 2–3%, but the real test is readability. The tool flags very high densities because they usually signal stuffed, awkward writing.

Not directly. Keyword density is not a ranking factor, and chasing a target percentage can make writing worse. Use the tool to confirm focus and catch stuffing, but always prioritise clear, helpful content written for people, not search engines.
Single-word analysis shows your most frequent individual terms, while two and three-word views reveal key phrases — the longer expressions your content emphasises. Phrases often reveal your true topic better than single words alone.
The tool lists the top 20 keywords or phrases by frequency for the selected phrase length. This keeps the results focused on the terms that matter most rather than overwhelming you with every word in the text.
Yes. You can paste long-form content and the tool will process it instantly in your browser. Word, character and sentence counts update alongside the density table, so you get a full picture of a complete article.
