Keyword Density Checker: Analyze Word Frequency & SEO | Free

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.

A The tool scans exact matches only. If you wrote 'SEO content strategy tips' but search for 'content strategy tips', it won't count because the word 'SEO' breaks the triplet. Try pasting your exact phrase without extra words. Or use the 2-word view — that catches partial matches more easily. A 3-word density of 0.5% with 10 appearances in a 2000-word article is usually fine.

A Absolutely. Paste your thesis or research paper into the checker. It'll reveal if you overuse terms like 'paradigm shift' or 'quantitative analysis' across 1-word, 2-word, and 3-word views. For a 10,000-word dissertation, spotting a 3-word phrase at 0.8% density tells you it's used 80 times — that's worth reviewing. One practical tip: run each chapter separately to catch section-level repetition you'd miss in the full document.

A Yeah, just copy and paste their text into the tool. Run competitor blog posts or landing pages through the 2-word and 3-word views to spot the exact phrases they're targeting. For example, if a rival's 1000-word page shows 'organic coffee beans' at 1.2% density, that's likely a priority keyword for them. One caveat: the tool doesn't scrape websites automatically. You'll need to manually grab the content yourself.
