Analyze your content's keyword frequency with professional precision. Optimize your on-page SEO by ensuring natural keyword balance without over-optimization.
This free keyword density checker analyzes any text or web page and tells you exactly how often each keyword appears and what percentage of your total content it represents. Use it to avoid keyword stuffing, confirm your content is properly optimized, and make sure Google can clearly understand what your page is about — all without leaving this page.
Getting keyword density right is one of the simplest and most overlooked parts of on-page SEO. Too many repetitions of the same phrase and your content reads unnaturally — and Google notices. Too few and you miss the opportunity to signal clearly what your page is about.
The sweet spot — typically 1% to 2% for a primary keyword — tells Google that your topic is clearly defined without triggering over-optimization filters. Combined with strong keyword placement (title, H1, first paragraph, at least one subheading), proper keyword density helps your content rank for the searches you're targeting.
Use this tool before publishing every piece of content as a quick final check. It takes less than 30 seconds and can catch issues that would otherwise quietly hurt your rankings.
Keyword density is the percentage of times a specific word or phrase appears in your content relative to the total word count. It helps search engines understand what your content is about and ensures you're not over- or under-using your target keywords.
Most SEO professionals recommend keeping keyword density between 1% and 2% for primary keywords. Going above 3% risks being flagged for keyword stuffing. Going below 0.5% may mean the keyword isn't prominent enough for Google to associate it strongly with your page.
Keyword stuffing is the practice of overloading a page with keywords to try and manipulate rankings. It makes content unreadable and violates Google's guidelines. Pages caught keyword stuffing typically drop in rankings. Always write naturally and use a keyword density checker as a final review, not a writing target.

The formula is: (Number of times the keyword appears ÷ Total word count) × 100. For example, if a keyword appears 15 times in a 1,000-word article, the keyword density is 1.5%.
