See tables of single-word (unigram), two-word (bigram) and three-word (trigram) phrases ranked by frequency.
Each keyword shows its count and percentage of total words. Aim for 1-2% density for your primary keyword to avoid over-optimisation.

Frequently Asked Questions
What is the ideal keyword density for SEO?
Most SEO experts recommend 1-2% keyword density for your primary keyword. This means your target keyword appears once or twice per 100 words. Going above 3% risks being flagged as keyword stuffing by search engines.
Does keyword density still matter for SEO?
While Google has moved toward understanding topic relevance and search intent, keyword density still provides a useful baseline. It helps ensure your target terms appear enough to signal relevance without sounding unnatural.
What is the difference between unigrams, bigrams and trigrams?
Unigrams are single words, bigrams are two-word phrases and trigrams are three-word phrases. Checking all three reveals your content's topical focus and catches long-tail keyword opportunities you might miss with single-word analysis.
Are common words (stop words) included in the analysis?
Common English stop words like 'the', 'is', 'and', 'in' are filtered out of the unigram list to surface meaningful keywords. They are kept in bigram and trigram analysis since phrases like 'how to' can be valid keywords.
How does this differ from Google Search Console keyword data?
This tool analyzes what is in your content right now, while Search Console shows what queries people actually used to find your pages. Use both together: check your density here, then compare with Search Console to spot gaps.
