Inclusion Ratio

Glossary

Inclusion Ratio

The percentage of your site's pages included by the search index, calculated by dividing the number of pages found in a search index by the total number of pages you have estimated to be on your site. For example, if yahoo reports that you have 20 pages indexed, and your content management system has 40 pages in it, your Yahoo! inclusion ratio is 50 percent.

A low inclusion ratio can be because:

• Dynamic URLs are penalized by crawlers
• Dynamic Content that is reachable only by search or drop down menus
• Absense of a proper sitemap for a dynamic or database driven content, which maps out the site for crawlers or spiders
• Unreachable dynamic content inside databases
• Improperly configured pages or robots.txt file
