Keyword Density Checker
Paste your content and enter a target keyword to see exactly how many times it appears and how dense it is relative to your total word count — helpful for avoiding both under-optimization and keyword stuffing.
Works with single words or full phrases — matching is not case-sensitive.
How to Use This Tool
Paste your content
Drop in your article, blog post or page copy — plain text is fine, HTML tags aren't needed.
Enter your target keyword
Type the exact word or phrase you're optimizing for, the same way you'd want it to appear.
Click "Check density"
The tool counts every occurrence and calculates density instantly in your browser.
Adjust and re-check
If density is too high or too low, edit your content and run the check again before publishing.
About the Keyword Density Checker
Keyword density is the percentage of times a target keyword or phrase appears relative to the total word count of a piece of content. It was once treated as a precise ranking formula to hit — write 1,000 words, use the keyword 20 times, done. Modern search engines don't work that way anymore; they understand context, synonyms and topical relevance far better than a raw repetition count.
Even so, density is still a useful sanity check. Content with a keyword density near 0% often means the page never clearly signals what it's about, which can hurt relevance. Content with density far above 3–4% often reads as repetitive or forced to an actual reader, and can look like keyword stuffing to search engines, which is a practice that can suppress rankings rather than help them.
Use this tool as a quick check, not a target to hit exactly. Write naturally for your reader first, then paste the result in here to confirm you haven't drifted into either extreme — under-using the keyword or over-stuffing it.
Frequently Asked Questions
What is a good keyword density percentage?
There's no single "correct" number, but most SEO practitioners treat roughly 1–2.5% as a healthy range for a primary keyword in long-form content. What matters more than hitting an exact percentage is that the keyword appears naturally in places that matter — the title, the first paragraph, a heading or two, and scattered through the body — rather than being repeated mechanically.
Can keyword stuffing get my page penalized?
Yes. Search engines are built to detect unnatural repetition, and content that reads as stuffed can be algorithmically demoted or, in more severe cases, manually reviewed and penalized. Beyond the ranking risk, stuffed content is also just unpleasant to read, which hurts engagement and conversions regardless of how it ranks.
Does this tool count partial word matches?
No, it matches your exact keyword or phrase as typed, case-insensitively. If you search for "tool" it won't separately count "tools" or "toolkit" as matches — for those variations, run the check again with each specific form you want to measure.
Should I optimize for keyword density or for readability?
Readability first, density second. Search engines increasingly reward content that reads naturally and answers the searcher's question clearly, so write for your human reader and treat this tool as a final check rather than a drafting target — if hitting a density number makes a sentence sound awkward, rewrite the sentence, not the number.
Does this tool account for keyword variations and synonyms?
No — it performs exact text matching only. Search engines themselves do understand synonyms and related terms through natural language processing, so this tool is best used as one input among several, not as a full picture of your content's topical relevance.
Is my content uploaded anywhere when I use this tool?
No. The counting happens entirely in your browser using JavaScript — the text you paste never leaves your device or gets sent to a server, so it's safe to use on unpublished drafts or confidential client content.
