Search Engine Marketing (SEM)
SEM comprises SEO and search engine advertising. Search engine advertising, in its current model, typically uses text-based advertisements that the marketer bids on based on the keywords the marketer wants to associate with the advertisement (contextual advertising). The business model is typically PPC. Goto.com pioneered the PPC model for search engine advertising. Goto.com was purchased by Overture which was ultimately purchased by Yahoo! Google's Google Adwords is the main competitor. Both these networks supply advertisements for other sites.
