Frequently Asked Questions

What is keyword density?
Keyword density is the percentage of times a keyword appears relative to the total word count. Formula: (Keyword Count ÷ Total Words) × 100.
What's the ideal keyword density?
Most SEOs recommend 1-2% for primary keywords. Focus on natural writing over hitting an exact number. Keyword stuffing (>3%) can hurt rankings.
What are n-grams?
N-grams are word sequences: 1-grams = single words, 2-grams = two-word phrases, 3-grams = three-word phrases. They reveal multi-word keyword patterns critical for long-tail SEO.
Why filter stop words?
Stop words (the, a, is, and) add no SEO value. Filtering them highlights your meaningful keywords and gives a clearer picture of topical focus.
How do I use this for SEO?
Ensure target keywords appear naturally (1-2%), check for unintentional stuffing, discover related phrases, and compare your density with top-ranking pages for the same query.
