Keyword Density Checker

Our free keyword density checker instantly analyzes any block of text and shows you the most frequent words and phrases, how many times each appears, and what percentage of your total content they make up. Paste an article, blog post, product description, or landing-page copy and get a clear breakdown of one-word, two-word, and three-word phrases in seconds, with no signup and no data ever leaving your browser.

Keyword density still matters for on-page SEO, but mostly as a guardrail against over-optimization. Search engines reward natural, readable writing, so a keyword density checker helps you confirm that your target phrase appears often enough to signal relevance without being stuffed unnaturally. Enter an optional target keyword and the tool reports its exact count and density so you can keep it in a healthy range (typically around 0.5%-2.5%) and spot accidental repetition before you publish.

Because everything runs client-side, you can check sensitive or unpublished drafts privately and as many times as you like. When you are ready to track how that optimized content actually ranks in local map results and organic search, ProMapRanker can help you measure the impact over time, start free.

FAQ

What is a good keyword density percentage?

There is no official rule, but most SEO practitioners aim for a primary keyword density of roughly 0.5% to 2.5% of total words. Anything much higher can read as keyword stuffing and risk over-optimization, while a very low density may not clearly signal your topic. Use this keyword density checker to keep your target phrase in a natural, comfortable range and prioritize readability for real people.

How is keyword density calculated?

Density is the number of times a word or phrase appears divided by the total number of words in your text, multiplied by 100. For multi-word phrases, the count is the number of times that exact sequence of words occurs. This tool tokenizes your text, optionally removes common stopwords for the single-word view, builds frequency maps for 1, 2, and 3-word phrases, and computes each percentage against the full word count.

Does this keyword density checker send my text anywhere?

No. All tokenizing, counting, and density math happens entirely in your browser using JavaScript. Your content is never uploaded to a server or any third-party API, so it is safe to analyze private drafts, client work, or unpublished pages.
