Keyword Density Checker

A keyword density checker that counts whole-word, case-insensitive occurrences of a keyword in your content and reports the density percentage — under 0.5% low, 0.5–2.5% natural, above 2.5% a stuffing risk.

Keyword density is the share of your content occupied by a target keyword — occurrences multiplied by the words in the phrase, divided by total words. It stopped being a ranking lever years ago (modern search engines read topics and synonyms, not raw counts), but it remains a useful sanity check in both directions: a density near zero suggests the page never clearly commits to its topic, while a high one reads as spam to humans and can trip over-optimization filters.

This checker counts whole-word, case-insensitive matches — searching for 'car' won't inflate the count with 'carpet' or 'scared' — and handles multi-word phrases with any spacing between the words. You get the total word count, the number of occurrences, the density to two decimals, and a plain verdict: under 0.5% reads as low, 0.5–2.5% is the comfortable range most SEO practitioners aim for, and beyond 2.5% you're flirting with keyword stuffing. Everything recalculates live as you edit, so you can tune a draft in place.

Use the number as a smoke alarm, not a target. If density is low, the fix is rarely to sprinkle the exact phrase mechanically — it's to check that the keyword appears where it structurally matters: the title, the first paragraph, at least one heading, and the meta description. If density is high, replace repetitions with natural variants and pronouns; if a sentence sounds robotic when read aloud, a search engine's spam classifier tends to agree. Write for the reader first, then verify the numbers here.
