How this tool works
Keyword density isn't a direct ranking factor anymore (Google called it 'overrated' in 2010), but it's still useful as diagnostic: if your article on 'mortgage calculator' mentions 'mortgage' 47 times, you're keyword-stuffing and will have problems. If it mentions it 0 times, you're not covering the topic.
This tool counts unique words, bigrams (pairs like 'mortgage latam') and trigrams ('mortgage calculator latam') and filters stopwords in Spanish and English (articles, prepositions, auxiliary verbs). Returns real percentage per keyword. 2026 SEO recommendation: primary keyword 0.5–1.5%, related semantics in abundance.
Frequently asked questions
- Ideal density?
- Primary keyword: 0.5–1.5% of total words. Over 3% signals stuffing. Under 0.3% in a 1000+ word article: probably not covering the topic.
- Bigrams or trigrams?
- Trigrams are your gold. 'Mortgage calculator latam' is the exact query people search. Optimize content so that trigram appears naturally 2–4 times.
- Useful for LLMs (ChatGPT, Perplexity)?
- Yes. LLMs don't use density for ranking, but they use it to understand document topic. Coherent density = LLM cites your site in relevant answers.
- What if I have stuffing?
- Rewrite using synonyms and related entities. 'Mortgage' can be 'home loan', 'housing finance', 'real estate financing' — Google treats them all as same semantic entity.
