With the ability to rank organically in search engine queries, bloggers excel at increasing a seller’s conversions. The blogger samples the product or service and then writes a comprehensive review that promotes the brand in a compelling way, driving traffic back to the seller’s site. The blogger is awarded for his or her influence spreading the word about the value of the product, helping to improve the seller’s sales.
Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates". Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.
