Keyword Density

What is Keyword Density?

Keyword density (Keyword Density) is a traditional SEO factor that describes the ratio between the number of a specific keyword and the total number of words on a web page. It is expressed as a percentage and was an important ranking factor in the early years of Web Optimization.

Calculating Keyword Density

Keyword density is calculated using the following formula:

Keyword Density = (Number of Keywords ÷ Total Word Count) × 100

Example:

• Text with 500 words
• Keyword "SEO" appears 10 times
• Keyword Density = (10 ÷ 500) × 100 = 2%
