Keyword Density Checker: Analyze Word Frequency & SEO | Free

A Keyword density is the percentage of times a keyword appears in a text relative to the total word count. Formula: (keyword count / total words) × 100.

A There is no magic number, but 1-2% for primary keywords is generally recommended. Focus on natural writing rather than exact percentages.

A Stop words are common words like the, is, and, a, etc. that are filtered out because they don't carry significant meaning for keyword analysis.

A Yes, completely free with no limits.

A Yes, absolutely! Paste your meta description text into the checker. While keyword density in meta descriptions doesn't directly influence ranking, it can improve click-through rates (CTR) by clearly communicating content relevance. Aim for natural inclusion of your target keywords to entice users and search engines to understand your page's focus.

A This tool is excellent for spotting keyword stuffing. By analyzing 1-word, 2-word, and 3-word keyword frequencies and their density percentages, you can quickly identify terms that appear unnaturally often. If a keyword's density is excessively high (e.g., over 3-4% for primary terms), it indicates potential stuffing. Use these insights to refine your content, ensuring natural language and better readability while still optimizing for search engines.

A The checker breaks down keyword frequency in three ways. 1-word analysis shows individual terms, like 'apple.' 2-word analysis looks at pairs, such as 'red apple.' 3-word analysis examines triplets, like 'tasty red apple.' This gives you a full picture of how phrases are used. For example, if 'SEO' appears 10 times in a 500-word article, its 1-word density is 2%. Seeing that 'SEO tips' only appears twice offers deeper insight.

A Yes, it works with any language that uses spaces between words. Paste Italian, Japanese (with spaces), or Spanish text and the tool counts words and density identically. One catch: stop word filtering is English-only right now. For non-English text, uncheck the stop word filter to see every term. Try pasting a German paragraph — you'll see 'der' and 'die' appear as keywords, which is useful for language learners too.
