What is Keyword Density?

Keyword density refers to the percentage of times a keyword appears within a piece of content compared to the total number of words.

It helps SEO professionals understand how prominently a keyword is used on a page.

The formula for keyword density is:

Keyword Density (%) = (Keyword Occurrences ÷ Total Words) × 100

For example:

• Total Words: 1,000
• Keyword Occurrences: 20

Keyword Density:

2%
