Keyword Density Checker

What the Keyword Density Checker does

The Keyword Density Checker analyzes a block of content and calculates what percentage of the total word count each word represents, giving you a data point for basic on-page SEO review.

How to use it

1. Paste your content into the box.
2. Click Analyze Keyword Density.
3. Review the resulting word list, ranked by density percentage.

Common uses

• Checking whether a target keyword appears at a reasonable, natural frequency in an article.
• Spotting unintentional overuse of a particular word or phrase before publishing.
• Reviewing a competitor's published content for its apparent keyword focus.
• Auditing existing pages as part of an on-page SEO review.
• Getting a rough content-focus check before finalizing a draft.

Good to know

There's no single "correct" keyword density percentage that guarantees better rankings — modern search engines evaluate content quality, relevance, and natural language far more than exact keyword percentages, so use this as a sanity check against obvious over-optimization rather than a target number to hit precisely.

Keyword density as an SEO metric was far more influential in the late 1990s and early 2000s, when search algorithms relied more heavily on literal keyword matching — modern search engines use much more sophisticated language understanding, which is why aggressive keyword stuffing is now more likely to hurt a page's perceived quality than help its ranking.
