SEM is a form of internet marketing that seeks to promote websites by increasing their visibility in search engine result pages through the use of paid placement, contextual advertising, and paid inclusion. It combines processes, features, additions and ongoing changes to a website in order to achieve top rankings in the major search engines. Google, Yahoo!, MSN, and others look for different ranking criteria. Online media buying services are those services which operate by advising, discussing and buying advertising space on behalf of enterprises or clients, keeping in mind the strategic elements of the marketing campaign.
