Everything you need to know about our free SEO tools
Keyword density is the percentage of times a keyword appears relative to total word count. It helps you gauge how naturally a keyword is used in your content.
Most SEO experts recommend 1-3% for your primary keyword. Going above 3% risks being flagged for keyword stuffing.
While Google uses semantic understanding, keyword density remains a useful guideline. Natural keyword usage signals topic relevance to search engines.
N-grams are contiguous sequences of words. 1-grams are single words, 2-grams are two-word phrases, and 3-grams are three-word phrases.
Common words like 'the', 'and', 'is' are filtered to surface meaningful keywords. This gives you a clearer picture of your content's topical focus.
