Keyword Density
The percentage of times a keyword appears on a page relative to the total word count.
Keyword density is the percentage of times a target keyword appears in your content compared to the total number of words. If your 1,000-word article mentions "SEO audit" 10 times, the keyword density is 1%.
In the early days of SEO, keyword density was a major ranking factor. People would stuff their keywords into content at a specific percentage (often 2-3%) thinking it would help them rank. This led to terrible, unnatural content.
Modern search engines are way smarter than that. Google uses natural language processing and semantic analysis to understand content. There's no magic keyword density number. Google's John Mueller has explicitly said they don't use keyword density as a ranking factor.
What matters is writing naturally and covering your topic thoroughly. If you're writing comprehensively about a subject, relevant keywords will naturally appear at appropriate frequencies. If you find yourself counting keyword instances, you're doing it wrong.
Why It Matters for SEO
Understanding keyword density helps you avoid two extremes: not mentioning your target keyword enough (so search engines don't know what your page is about) and mentioning it too much (keyword stuffing). The goal is natural, reader-friendly content.
