Frequently asked questions

What is a keyword density checker?

A keyword density checker measures how often a target keyword or phrase appears in a piece of content compared with the total word count.

What keyword density is good for SEO?

A practical target is usually about 0.5% to 3% for important keywords, but natural writing and search intent matter more than hitting an exact number.

Can keyword density be too high?

Yes. Repeating a keyword too often can make copy sound forced, reduce readability, and create keyword-stuffing risk.

Does this checker upload my content?

No. The analysis runs in your browser, so pasted drafts stay on your device.
