## Keyword density

Measures the ratio of keyword occurrences to total words, guiding SEO relevance, UX readability, and CRO effectiveness.



## Why Keyword Density Matters

#### Semantic context

Including related terms enhances topic coverage and supports keyword density without exact repetition.

#### Readability and flow

Overusing keywords can disrupt reading patterns and distract users from your core message.





### Conversion rate optimization (cro)

#### Cta alignment

## How to Calculate Keyword Density
