Enter some text and click Analyze to see keyword density results.
This free online tool analyzes the keyword density of any text content. Keyword density is the percentage of times a keyword or phrase appears on a page compared to the total number of words. It helps content creators and SEO professionals optimize their content for search engines without over-optimizing (keyword stuffing). All processing happens entirely in your browser — your content never leaves your device.
Most SEO experts recommend a keyword density of 1-2%. Above 3% may be considered keyword stuffing by search engines. This tool marks 1-2% as "Optimal", below 1% as "Low", 2-3% as "High", and above 3% as "Stuffing".
While search engines now use much more sophisticated algorithms than simple keyword density, having your target keyword naturally appear in your content is still a positive signal. This tool helps you ensure your content is well-balanced.
Absolutely. All analysis happens entirely within your browser. No text is transmitted to any server.
Stop words are common words (like "the", "is", "at", "which", "on") that are filtered out during analysis because they don't carry meaningful semantic weight for SEO purposes.
