Analyze word frequency and keyword density to optimize your content.
### The Ultimate Free Keyword Counter & Density Checker When writing content for SEO, balancing your keyword usage is critical. If you use a keyword too rarely, search engines might not understand your topic. If you use it too frequently, you risk being penalized for **keyword stuffing**. Our **Free Keyword Counter** is engineered to help SEO professionals, copywriters, and marketers perfectly balance their content in real-time. ### How it Works (100% Client-Side Privacy) Unlike traditional SEO software that requires you to upload your unreleased articles to their servers, our Keyword Counter analyzes your text entirely inside your browser. This guarantees absolute privacy for your confidential drafts and client work. It instantly breaks down your text to show the exact frequency and density percentage of every single word. ### Why You Need a Keyword Density Checker - **Avoid Penalties:** Keep your primary keyword density between 1% and 3% to stay safe from algorithm penalties. - **Discover LSI Keywords:** Analyze competitor articles to see which secondary keywords they are targeting. - **Improve Readability:** Spot overused filler words that might be hurting your writing quality. Just paste your article, and our algorithm will instantly strip away punctuation, ignore common stop-words (like 'and', 'the', 'is'), and give you a clean, sorted table of your most valuable keywords.

Most SEO experts recommend keeping keyword density between 1% and 2%. Anything higher might be penalized by Google as "keyword stuffing".
Currently, the tool focuses on single-word frequency (unigrams) to give a baseline analysis of your text's vocabulary.
