An SEO contest is a prize activity that challenges search engine optimization (SEO) practitioners to achieve high ranking under major search engines such as Google, Yahoo, and MSN using certain keyword(s). This type of contest is controversial because it often leads to massive amounts of link spamming as participants try to boost the rankings of their pages by any means available. The SEO competitors hold the activity without the promotion of a product or service in mind, or they may organize a contest in order to market something on the Internet. Participants can showcase their skills and potentially discover and share new techniques for promoting websites.
