What is a Keyword Density Checker?

A keyword density checker is an SEO tool that analyzes your text to show:

✔ How often keywords appear (as percentage of total words)
✔ Optimal keyword distribution for better rankings
✔ Over-optimization alerts (to avoid penalties)

Example Report:

*"SEO" appears 15 times (3.2% density) in 500 words - ideal range is 1-3%*
