How to use

How to use the Keyword Density Checker

01
Aim for 1-3% density on your primary keyword
Higher density is not better — anything over 3% may signal keyword stuffing to Google. Natural language and semantic variations matter more than hitting a specific number.
02
Check 2-word and 3-word phrases, not just single words
Long-tail keyword phrases often carry more ranking intent than individual words. A page about 'best running shoes' should have that exact phrase appear naturally, not just 'running' and 'shoes' separately.
03
Use this tool to audit competitor content
Paste a top-ranking competitor's content to see which keywords they emphasize. This reveals content gaps in your own writing without copying their approach.

Frequently asked

About the Keyword Density Checker

1-3% for your primary keyword is the accepted range. Above 3% risks being flagged as keyword stuffing. Focus on natural language and semantic variations instead of hitting a specific number.

Indirectly. Google does not use a strict density threshold, but unnaturally repeated keywords hurt readability and can trigger spam filters. Use this tool to check you are not accidentally over-optimizing.

Stop words (the, a, is, etc.) appear in every piece of text and carry no topical signal. Filtering them shows you which meaningful content keywords dominate your writing.
