(p d in-kloo zh&n) (n.) Paid inclusion is a search engine marketing model in which a website pays a fee to a search engine that guarantees that the site will be displayed in the returned search results for specifically named search terms.For example, a Web site that sells baseball trading cards can pay a search engine to ensure that its site is returned in the search results when a user searches on the phrase “vintage baseball cards.”
Paid inclusion, for some search engines, also means that the search engine’s spiders will crawl their sites more often than non-paid sites. Different search engines treat paid inclusion results differently; some indicate the paid inclusion results as advertisements while others display them as results alongside non-paid search results.
