About Keyword Density Checker
The Keyword Density Checker analyzes any block of text and shows you which words appear most often. Paste or type your content and it instantly counts the total words, then ranks the top single keywords by frequency, showing each word with its count and density percentage (how much of the total word count it makes up). Common stop words like "the", "and", and "of" are ignored so the results reflect the words that actually matter.
It is completely free with no sign-up, no limits, and no ads to click through. Everything runs entirely in your browser as you type, so your text is never uploaded to a server. It is a fast way to spot keyword stuffing, check that your target term appears often enough, and tighten up content for SEO.
Frequently asked questions
- Is the Keyword Density Checker free to use?
- Yes, it is completely free with no account, no sign-up, and no usage limits. You can check as many pieces of text as you want, as often as you like.
- Is my text uploaded or stored anywhere?
- No. All analysis happens locally in your browser using JavaScript. Your text is never sent to a server, saved, or shared, so it stays completely private.
- What is a good keyword density for SEO?
- Most SEO practitioners aim for a natural range of roughly 1% to 2% for a primary keyword. There is no exact rule, but very high densities can look like keyword stuffing to search engines, so writing naturally is best.
- How is keyword density calculated?
- Density is a keyword's count divided by the total number of words in your text, multiplied by 100 to get a percentage. For example, a word used 5 times in a 500-word article has a density of 1%.
- Why are words like "the" and "and" not shown?
- Common stop words are filtered out because they appear frequently in all writing and carry little meaning. Ignoring them lets the ranking surface the keywords that actually describe your content.
- Does it count phrases or only single words?
- This tool measures single-word keyword density and shows the top individual words by frequency. It does not group multi-word phrases, so each word is counted on its own.
