Frequently Asked Questions
What is the ideal keyword density?
Most SEO experts recommend a keyword density between 1% and 3% for your primary keyword. Going above 3% may trigger keyword stuffing penalties from search engines. Focus on writing naturally and let the density fall within this range organically.
What are n-grams?
N-grams are sequences of N consecutive words in your text. A 1-gram (unigram) is a single word, a 2-gram (bigram) is a two-word phrase like "content marketing", and a 3-gram (trigram) is a three-word phrase like "search engine optimization". Analyzing all three levels reveals your content's full keyword profile.
Does keyword density still matter for SEO?
While Google has moved toward semantic understanding and no longer relies solely on keyword density, it still matters as a baseline. Extremely low density means your content may not be relevant enough, while extremely high density signals spam. Use density as a guide, not a strict rule.
How do I avoid keyword stuffing?
Write for humans first, then check your density. Use synonyms and related terms instead of repeating the exact same keyword. If your primary keyword exceeds 3% density, rephrase some instances. Focus on comprehensive topic coverage rather than keyword repetition.
