The number of times a keyword appears in a given area. For example keyword density of a web page is an indicator of how many times a keyword appears on that page. Keyword Density is typically measured as a percentage and is calculated by the number of times the selected keyword appears within a given portion of text or copy.

Common areas where keyword density is important include:

• - Page Titles
• - Meta Tags ( meta description and meta keywords tags )
• - Page Headings
• - Page Copy
• - Alt Text

Some say that keyword density is not as important as other on-page SEO factors, however in order to be an authority on a given topic, you should have proper keyword density on site pages and throughout your site.
