]In the world of Search Engine Marketing (SEM), “click” is a very important term. In fact, “click” (used as either a verb or a noun) describes a very specific action that any Internet user performs while conducting a search in any search engine.

Up until recently, all search engines had relatively complete freedom to decide how clicks should be counted and how to charge YOU (as an advertiser) based on that definition. Enter the dreaded phrase “click fraud” – how can advertisers and search engines possibly agree on what “click fraud” is, when there is no set definition for the word “click”?
