The Stock Managers of Domains, SEO Marketers, Hosts of websites and number of other services providers. They create a market in such a way that we feel to buy their services.
Google decides upon some strategy of ranking of websites. These service providers analyze google strategy and create software to help websites to rank in Google at a price.
