Paid inclusion is a practice used in the field of otimização de motores de busca[1] where companies pay to have their websites included in a motor de busca[2]’s search results. This practice is different from paid placement, which involves companies paying for a higher ranking in search results, regardless of the relevance of their sítio Web[4]. Paid inclusion simply guarantees a spot in the search results, but not a top ranking. This practice has been used by various search engines as a source of revenue, including Inktomi, Microsoft[3], and Yahoo. Google[5], which initially avoided paid inclusion, reintroduced it in a modified form in 2012 through programs like Google Flights and Google Shopping. The practice has both supporters and critics, with some praising its ability to reduce spam and improve the relevance of search results, and others arguing that it prioritizes economic interests over relevance for users. The Federal Trade Commission (FTC) recommends that search engines clearly distinguish between paid placement and paid inclusion, although this is not a legal requirement.
Inclusão paga é um search engine marketing product where the motor de busca company charges fees related to inclusion of sítios Web in their search index. The use of paid inclusion is controversial, and paid inclusion's popularity has decreased over time among search engines.
