## What Is Keyword Density?
Keyword density refers to the percentage of times a specific keyword appears in your content compared to the total number of words on the page.
### Simple Formula:
[
Keyword Density = (Number of times keyword appears ÷ Total word count) × 100
]
For example:
If your article contains **1000 words**, and your target keyword appears **20 times**, then:
[
(20 ÷ 1000) × 100 = 2%
]
That means your keyword density is **2%**.

## Why Keyword Density Matters for SEO
Search engines like Google analyze content to understand its topic and relevance. Proper keyword usage helps search engines determine what your page is about.
However, there is a balance:
* Too low → Search engines may not understand your focus topic.
* Too high → It may look like keyword stuffing (which can harm rankings).
A keyword density tool helps maintain that balance.
### Benefits of Using a Keyword Density Tool
* ✔ Prevents keyword stuffing
* ✔ Improves on-page SEO
