Keyword density refers to how frequently a specific keyword appears within content compared to total word count, influencing SEO rankings.
What Is Keyword Density?
Keyword density is a key SEO metric that measures the frequency of a target keyword within a webpage or article. It’s expressed as a percentage and helps content creators determine if a keyword is being used appropriately—or excessively.
How to Calculate Keyword Density:
The formula is:(Number of times keyword appears / Total word count) x 100
Example:
If your keyword appears 10 times in a 1,000-word article:(10/1000) x 100 = 1% keyword density
What’s the Ideal Keyword Density?
There’s no exact rule, but generally a keyword density between 0.5% to 2.5% is considered optimal. Anything higher may risk keyword stuffing, which can harm SEO performance.
Why Keyword Density Matters:
- Ensures keywords are present enough for SEO
- Avoids keyword stuffing penalties
- Improves content relevance and targeting
- Helps with semantic understanding by search engines
Best Practices:
- Focus on natural keyword placement
- Use variations and related terms
