Frequently Asked Questions
Keyword density is how often a keyword appears in your text as a percentage of total words. A keyword that appears 10 times in a 1000-word article has a density of 1%.
Most SEO experts recommend 1–3% keyword density. Over-optimizing (keyword stuffing) above 5% can trigger Google penalties. Focus on natural, helpful writing rather than hitting a specific percentage.
Keyword Density (%) = (Number of times keyword appears ÷ Total word count) × 100. For example, a word appearing 15 times in a 500-word article has a density of 3%.
Common stopwords (the, a, and, is, it, etc.) are automatically excluded so you see meaningful content keywords only.
