What is Paid Inclusion? (and how does it differ from paid search?)

Paid inclusion (PI) is a program which allows site owners to submit individual pages to a search engine for inclusion into its index. Web pages submitted to the engines in this manner are typically mixed into the general organic search results.

Advertisers pay a fixed cost per click for the service, based on their site’s subject matter.

Unlike paid search, paid inclusion programs do not guarantee that submitted pages will appear for a desired keyword. Instead, site owners are simply paying to guarantee that their pages will be included and regularly updated in the engines’ index.
