DocomintKeyword Density Checker
See which words appear most often in your content, as a percentage of total word count.
What is a Keyword Density Checker?
Similar to Word Frequency Counter, but filtered for SEO/copywriting use: common stopwords (the, and, of...) are excluded so the ranked list shows the actual topic words your content repeats, along with what percentage of total words each one makes up — useful for checking a page isn't accidentally over- or under-emphasizing its target keyword.
How to use the Keyword Density Checker
- Paste your article, product copy, or page content
- Common stopwords are filtered out automatically
- Keyword density percentages appear instantly, on your device
Example
A 150-word product description that says "coffee" 6 times comes back with coffee at 4.0% density.
Frequently asked questions
What keyword density is considered too high?
There's no official cutoff, but most SEO guidance treats anything consistently above roughly 3-4% for a single keyword as a sign of unnatural repetition — write for readability first and treat this as a sanity check, not a target to hit.
Is my text uploaded anywhere?
No — Keyword Density Checker runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
What counts as a 'stopword' that gets filtered out?
Common function words that carry little topical meaning on their own — articles like 'the' and 'a', conjunctions like 'and', prepositions like 'of' and 'in' — using a standard English stopword list, the same category of words most SEO tools exclude.
