Keyword Density Checker

The Keyword Density Checker analyzes a block of text or the visible content of a live page and reports how often each word and phrase appears relative to the total word count. It tokenizes the content, counts single words and multi-word phrases (n-grams like two- and three-word combinations), filters common stop words, and ranks the most frequent terms with their raw counts and percentage density. This gives you a quick map of what a piece of content is actually about in the eyes of a topic-matching algorithm.

You can paste text directly or point the tool at a URL so it extracts the readable body content before analyzing it. The output highlights your dominant terms and phrases, which helps you confirm that a page emphasizes its target topic without tipping into unnatural repetition. Modern search engines reward natural, comprehensive coverage of a subject rather than a specific keyword percentage, so the tool is best used to spot imbalances — a primary keyword that barely appears, or a term that's been stuffed far more than reads naturally.

Common use cases include reviewing a draft article before publishing, comparing your content's term distribution against a top-ranking competitor's page, finding accidental over-optimization on older pages, and discovering related phrases you've covered well enough to lean into. Copywriters and SEO editors use it as a sanity check that the topic and its supporting terms are present and proportionate.

Practical tips: there is no magic density number — aim for content that reads naturally and covers the topic thoroughly rather than chasing a percentage. Watch for keyword stuffing, which can read as spammy and harm trust, and pay attention to two- and three-word phrases since they often capture intent better than single words. Use this alongside readability review and the Keyword research process to refine which terms deserve emphasis, not as a rule that dictates exact repetition counts.
