What is Keyword Density Checker?
Keyword density measures how often a keyword appears in your content as a percentage of total words. This tool tokenises text, counts every word and phrase, and presents a density table with SEO scoring to spot over-optimisation instantly.
Why It Matters for SEO
Keyword stuffing above 3-4% triggers Google spam filters. Under-using a keyword signals weak topical relevance. The sweet spot is 1-3% for primary keywords in most content.
How to Use This Tool
- 1 Paste your article or page copy
- 2 Set the minimum occurrence count to filter rare words
- 3 Enable stop-word filtering to remove noise words
- 4 Choose phrase length (1, 2, or 3-word analysis)
- 5 Review the density table and colour-coded badge scores
