Free Content SEO Tool
Use this keyword density checker to measure exact phrase frequency, density, word positions, and section distribution in English or Chinese SEO copy before publishing.
Paste a product page, category page, resource article, or landing-page draft and enter one primary keyword. The checker reports whether the phrase appears naturally across the copy instead of only in one isolated section.
Density equals the number of matched keyword words divided by total words. A two-word phrase found three times contributes six matched words, so editors can compare short and multi-word keywords consistently.
Word positions and quarter-by-quarter counts reveal whether the target phrase appears near the introduction, through the body, and toward the conclusion. This supports page-topic clarity without forcing repetition.
Keyword density is a diagnostic signal, not a ranking target. Keep useful buyer questions, specifications, proof, and clear internal links in the copy, then remove awkward repetitions that reduce readability.
There is no universal ideal percentage. Use density to find missing or excessive repetition, then prioritize readable, complete content that matches search intent.
It matches the normalized token sequence and multiplies each match by the number of words in the phrase when calculating density.
Not by itself. Search engines evaluate relevance and usefulness across the whole page; forced repetition can make content weaker and less trustworthy.
