Analyze keyword usage, density, and top keywords in your content.
Understanding how often your keywords appear in your content is a small part of SEO. Keyword Density Checker analyzes your text to show word frequency, keyword density percentages, and top keywords — entirely in your browser, nothing sent anywhere.
Paste your content, optionally enter a target keyword, and click Analyze. The tool shows your content's overall statistics, your target keyword's density (if provided), and the most-used keywords in your text.
Keyword density is how often a word or phrase appears compared with the total word count. If a phrase appears 8 times in a 1,000-word article, its density is 0.8%. The tool also lists your most-used words and shows word, character, sentence and paragraph counts, which helps you spot overused terms and check length.
No. Search engines do not use a fixed target, and repeating a phrase to hit a number reads badly and can look like keyword stuffing. Use density as a sanity check instead: make sure your main topic appears naturally in the title, headings and opening paragraph, and look for unnatural repetition. Natural variations, synonyms and related terms usually matter more than raw counts. Write for the reader first.
Then polish the page-level tags with the Meta Tag Generator, prepare crawl rules with the Robots.txt Generator, generate topic ideas with the Keyword Generator and use the Word Counter for quick length checks. Your text is analysed in your browser and never uploaded.
Does keyword density still matter for SEO?
Not the way it used to. Google's ranking systems today weigh topical coverage, content quality, and genuine relevance far more heavily than any specific keyword-repetition percentage — there's no target density that improves rankings on its own. This tool is most useful as a sanity check against accidental keyword stuffing, or to see your content's natural keyword balance, rather than as a number to optimize toward.
What's a good keyword density?
There's no universal 'correct' keyword density — it depends on your content, audience, and search intent. Writing for humans first, and using keywords naturally, is more important than hitting a specific percentage.
Why does my keyword not show a result?
Make sure the keyword appears as a standalone word or complete phrase in your text. Partial matches (e.g., 'car' inside 'carpet') are not counted.
Does this work with multi-word phrases?
Yes. Type your phrase exactly as you want it counted — 'web design' will count that phrase as a single target, not 'web' and 'design' separately.
