Keyword Density Checker

Keyword density is the percentage of times a keyword appears compared to total words. Formula: (keyword count / total words) x 100. For a 1000-word article with 15 keyword mentions, density is 1.5%. This applies to both single words and phrases.

Most SEO experts recommend 1-3% for primary keywords. However, there's no magic number—Google's algorithms have evolved beyond simple keyword counting. Focus on natural writing that thoroughly covers your topic, using keywords where they fit naturally.

Keyword stuffing means unnaturally repeating keywords to manipulate rankings. It results in poor user experience and can trigger Google penalties. Signs include awkward phrasing, repetitive sentences, and density above 4-5%. Modern SEO rewards helpful content, not keyword manipulation.

Yes, analyze your primary keyword plus secondary keywords and related terms. Each should have appropriate density. If targeting "best running shoes," also check "running," "athletic footwear," and related terms to ensure balanced, topically comprehensive content.

It matters less than before, but isn't irrelevant. Keywords still signal topic relevance, but Google now understands context, synonyms, and user intent. Focus on comprehensive, helpful content first. Use density checking to catch obvious issues, not as a primary optimization target.
