Search Engine Marketing (SEM)
The concept behind Search Engine Marketing is quite simple: when a consumer or business person searches the Web through either a text box or by clicking through a directory hierarchy, he or she is in “hunt mode.” This psychological state is unique because it signals to the search engine (and to marketers) that the person is looking for information, often of a direct or indirect commercial nature.
Marketers understand that this “hunt mode” means that the searcher may very well be at the beginning, middle, or end stages of the buying cycle. When someone is researching a product or service to satisfy an immediate or future need they are in an unusual state: they desire relevant information and are open to digesting and acting on the information at their fingertips, all made possible by a search engine. This makes search engine results some of the best sources of targeted traffic, whether this traffic originates from “organic” unpaid search listings or paid advertising listings.
