What does Word Count & Keyword Density do?
Word Count & Keyword Density fetches a live URL, strips navigation and boilerplate, and analyzes only the readable body copy. It reports total words, unique words, and lexical diversity, then builds keyword-density tables for single words and for two- and three-word phrases (n-grams), each with raw counts and the share of total words on the page.
Why density still matters: Search engines no longer reward simple keyword repetition, but density is a fast proxy for topical focus. A term that never appears under-signals the topic; a term repeated far too often reads as stuffing and can trigger spam patterns. This tool shows where you sit on that spectrum so you can edit with intent.
Target keyword prominence: Enter a focus phrase and the tool returns its exact count, density, and a prominence score built from placement signals - whether it appears in the title, the first H1, and the first 100 words. Prominence, not raw frequency, is what tends to correlate with relevance.
N-gram phrase analysis: Single-word counts miss intent. Two- and three-word phrases surface the actual queries your copy is built around, so you can confirm a page reinforces its target phrase instead of a scattered bag of related words.
Use cases: Audit thin or bloated content before publishing, compare a draft against a competitor's word count, catch accidental over-optimization, and verify that a rewrite actually moved your focus keyword into the title and intro.
When should you use Word Count & Keyword Density?
Word Count & Keyword Density is most useful when you need a direct answer on a live URL or draft before you change templates, ship content, or rerun a wider audit.

Phrase-Level Density
N-gram tables surface the two- and three-word phrases that map to real search intent, not just isolated keywords.
Prominence, Not Just Frequency
Your target keyword is scored on where it appears - title, H1, and intro - because placement signals relevance more than raw repetition.
Frequently Asked Questions
Word Count & Keyword Density についての回答
There is no exact target, but a focus keyword in the 0.5% to 3% range is a safe, natural band for most pages. Modern search engines reward relevance and intent over repetition, so write for readers first. Use density as a guardrail: a 0% reading means the term is missing, while anything above roughly 4% starts to read as keyword stuffing.
This tool counts only the readable body text, with navigation, headers, footers, scripts, and structured data removed. Your CMS character or word count usually includes drafts, hidden fields, or template chrome. The number here reflects the prose a visitor and a crawler actually read on the live page, which is the count that matters for content depth.
Prominence measures where a keyword appears, not just how often - the title, H1, and first 100 words carry the most weight. N-grams are multi-word phrases: a bigram is two words and a trigram is three. Tracking phrase density alongside single words shows whether your copy reinforces a coherent target query instead of scattering unrelated terms.
Density itself is not a direct ranking factor, but it is a useful diagnostic for topical focus and over-optimization. Google ranks on relevance, intent, and quality, so stuffing a keyword to hit a percentage will not help and can hurt. Use this tool to confirm your topic is clearly present and prominently placed, then optimize the writing for the reader.
