Check on-page keyword density for SEO
Paste a draft blog post or landing page and instantly see your top keywords ranked by count and density percentage. Confirm your target term appears often enough to signal relevance, but stays within a natural range so search engines do not read the page as thin or off-topic. Adjust the copy and re-check until the numbers feel right.
Catch keyword stuffing before publishing
If one word shows a suspiciously high density percentage, that is a red flag for over-optimization that can hurt rankings or read awkwardly. Spot the offending term at the top of the table, rewrite a few sentences with synonyms, and watch the percentage drop back to a safer level before you hit publish or hand the article to a client.
Find overused words in your writing
Turn off Ignore common words to see every repeated term, or leave it on to surface only the meaningful ones. Either way, the frequency table reveals crutch words and phrases you lean on too heavily, so essays, emails, and reports read with more variety. Everything runs in your browser, so even unpublished drafts never leave your device.
Keyword Density Checker — frequently asked questions
What is keyword density?
It is how often a word or phrase appears relative to the total word count, shown as a percentage. For example, a term used 5 times in a 500 word article has a density of one percent.
What density should I aim for?
There is no exact target Google rewards, but keeping your main keyword in a natural range, often cited around one to two percent, is sensible. Write for readers first and use density as a sanity check, not a rule.
Can high keyword density hurt my rankings?
Yes, cramming a keyword unnaturally can read as stuffing, which search engines may treat as spam. This tool helps you catch terms that are repeated too aggressively so you can rephrase them.
