What is keyword density?+
Keyword density is the percentage of times a target keyword appears relative to the total word count. Formula: (keyword count ÷ total words) × 100. A density of 1.5% on a 1,000-word article means the keyword appears 15 times.
What is the ideal keyword density for SEO?+
Most SEO experts recommend 0.5%–2.5%. Below 0.5% and the page may not signal relevance strongly enough. Above 3–4% risks a keyword stuffing penalty from Google. Quality and natural usage matter more than hitting an exact number.
Does keyword density still matter in 2025?+
Yes, but less mechanically than before. Google uses semantic understanding to judge relevance, so phrase variations and LSI keywords matter as much as exact-match density. Use the target keyword naturally and vary it with synonyms and related terms.
What are n-gram frequencies?+
N-grams are sequences of n consecutive words. The tool shows the most-repeated 2-word (bigram) and 3-word (trigram) phrases in your content. High-frequency phrases reveal your content's actual topic clusters — often more useful than single-keyword density.
