Frequently Asked Questions
Keyword density is a percentage that shows how many times a target keyword or phrase appears in a piece of text compared to the total number of words. It's calculated as: (Number of times keyword appears / Total words) * 100.
While modern search engines are complex, keyword density is still a signal of a page's topic and relevance. For SEO, it helps crawlers understand what your page is about. For AEO, maintaining a natural density of key terms and related phrases helps AI systems recognize your content as a comprehensive and authoritative source on that topic.
There is no "perfect" percentage, and it's crucial to avoid "keyword stuffing" (unnaturally high density). Most SEO experts recommend a density of around **1% to 2%**. The most important thing is that the text reads naturally. Use this tool to check for over-optimization and to discover related semantic phrases from the 2-word and 3-word lists to use instead of repeating the main keyword.
