Keyword Density Checker
Check how often a target keyword appears in your content, plus top word frequency.
Keyword density — how often a target term appears relative to a page's total word count — was once treated as a precise ranking lever, leading to the now-outdated practice of unnaturally repeating a keyword to hit a specific percentage. Modern search engines are far more sophisticated about understanding topical relevance through natural language, but keyword density is still a useful diagnostic: content with essentially zero mentions of its target keyword phrase is a red flag that the page may not be well-targeted, and content that's stuffed unnaturally often reads poorly to actual readers regardless of any SEO effect.
This tool paste-and-analyzes your content two ways: a specific density check against a target keyword or phrase you specify, and a general top-words-by-frequency breakdown (excluding common stop words like "the" and "and") that reveals what your content is actually about, which sometimes surprises writers who intended to focus on one topic but drifted in the actual text.
