Keyword Density Checker

The Keyword Density Checker analyzes how frequently target keywords appear in your content relative to total word count, giving you a clear breakdown of frequency counts and density percentages for every term. Search engines use keyword frequency as one of many signals to determine topical relevance, but over-optimization — commonly called keyword stuffing — can trigger algorithmic penalties that push your pages out of the top results entirely. This tool helps you walk that fine line by showing exactly where your content stands. Aim for a primary keyword density between 1% and 2%, with secondary keywords falling in the 0.5% to 1% range. If the tool reveals that any term exceeds 3% density, that is a strong signal to rewrite those sections using synonyms, semantic variations, and related phrases to distribute relevance more naturally. Pay close attention to exact-match repetition patterns, because Google's SpamBrain system is specifically trained to detect unnatural keyword repetition. Beyond raw percentages, consider the placement of your keywords: terms in headings, the first paragraph, and image alt text carry disproportionate ranking weight compared to keywords buried in the middle of body copy. Use this tool after every draft revision to make sure your edits have not accidentally skewed your density in either direction. Pro tip: run your top three competitors' content through this same checker for your target keyword — matching their density range is almost always safer and more effective than following generic percentage guidelines, because it reflects what Google is actually rewarding in your specific niche and search context.
