Keyword Density Analyzer
Analyze keyword frequency and density to optimize your content for SEO.
Why it matters
Keyword density reveals whether your content is optimized or over-optimized
Search engines use keywords to understand what a page is about. If your target keyword appears too infrequently, the page may rank for the wrong queries — or not rank at all. If it appears too often, the content reads like spam and can trigger over-optimization penalties.
The ideal keyword density varies by topic and competition, but most SEO experts recommend keeping it between 1% and 2% for primary keywords. Secondary and related keywords should appear naturally throughout without exceeding 0.5% each individually.

FAQ
Common questions about Keyword Density Analyzer
What is keyword density?
Keyword density is the percentage of times a keyword appears in your content relative to the total word count. For example, if 'SEO' appears 20 times in a 1,000-word article, the density is 2%.
What is the ideal keyword density for SEO?
Most SEO experts recommend a primary keyword density of 1-2%. However, there is no magic number — natural language that reads well to humans is always the priority.
Does keyword density still matter for SEO?
Google's algorithms have evolved beyond simple keyword matching, but keyword density still provides a useful signal for topic relevance. More importantly, it helps you identify over-optimized content that reads poorly.
How do I use this analyzer to improve my content?
