What the Keyword Density Checker does
Paste an article and see which words and phrases appear most often, with each one's share of the total word count. If 'leather jacket' shows up 14 times in a 700-word page, you'll see it sitting at 2% — no spreadsheet formulas needed.
The report splits single words, two-word pairs and three-word phrases, so you can spot both a repeated term and a repeated expression.
Why the Keyword Density Checker is useful
Writers aiming at a search topic often overuse their main phrase without noticing, and pages that repeat one phrase every other sentence read badly and can look manipulative to search engines. A density report makes the repetition visible before you publish.
It works the other way too: if your main term barely appears, the page may not signal its topic clearly at all.
Also known as: keyword density, seo keyword checker, free keyword density checker, online keyword density checker, keyword density checker online free, keyword density checker tool, best keyword density checker tool.

Real-life use cases
Auditing a product page
An e-commerce writer checks a 400-word description and finds 'durable' used 11 times; she swaps half of them for specific details like the fabric weight.
Checking a guest post
An editor pastes a submitted article and sees the author's name appears more than the topic — a sign the piece is promotion, not information.
Tightening a blog draft
A blogger notices 'just' and 'really' in her top ten words and deletes most of them, making the prose noticeably crisper.
Tips for the best results
- There is no magic percentage — use the report to find extremes, not to hit a target number.
- Check the two- and three-word phrases; awkward repetition usually hides there, not in single words.
- Run the check after your final edit, since every rewrite changes the counts.
Conclusion
Paste your draft, read the table, and fix the words doing too much work.
Frequently asked questions
What is keyword density?
- It's how often a word or phrase appears as a percentage of the total word count. Ten uses in 1,000 words is 1%.
Is there an ideal density for SEO?

Does it count common words like 'the'?
- Yes, everything is counted. You can ignore the obvious filler at the top of the list and focus on your topic terms.
Can I check a competitor's page?
- Yes — copy the visible text from any public page and paste it in.
Does it handle other languages?
- It counts words in any language that uses spaces between words.
Is my article uploaded?
