Keep your keyword usage natural — no stuffing, no guessing.
Healthy range for most content: roughly 0.5%–1.5%. Above 2.5% usually reads as stuffed.
There is no magic number, but most ranking pages keep their main keyword between 0.5% and 1.5% of total words, supported by natural synonyms and related terms. Chasing an exact percentage matters far less than covering the topic well — this checker simply helps you spot accidental over-use before you publish.
Keyword density in SEO is the share of your text taken up by a word or phrase, shown as a percentage of total words. Paste your draft above, enter the phrase, and this tool shows the count and the percentage instantly. The keyword density formula, with an example: density = (times the keyword appears × words in the keyword) ÷ total words × 100. For example, a two-word phrase used 4 times in a 400-word text is (4 × 2) ÷ 400 × 100 = 2%. The commonly cited ideal keyword density for SEO content is roughly 0.5%–1.5% for a main keyword — a guideline, not a Google rule.
