About this tool
Get a readability score, density health check and stuffing warnings in one place. The tool flags any keyword above 3% as over-used and above 5% as stuffing, and grades readability with the industry-standard Flesch-Kincaid formula so your content stays both optimized and easy to read.
Frequently asked questions
What Flesch-Kincaid score should I aim for?
A score of 60 or higher (around 8th-grade reading level) is a safe target for most web content. Lower scores read as more difficult.
When is a keyword considered stuffed?
This tool warns at 3% density (over-used) and flags 5% or higher as keyword stuffing, which can hurt rankings.
