Google AdWords is a way for businesses to promote their products online; for example, when people are searching for resort packages, tours, or flights for a trip or vacation. Displaying products to customers at the time that they are looking for related content is called intent-based marketing. Being at the top of the first page of a Google search is a good way to be seen. AdWords help to do this by telling Google the searches for which a business wants its advertisement to be found. There is no sign-up cost and no cost for Google support to help clients find keywords that are right for them, but businesses do pay when someone either clicks to visit their website or calls them. How do AdWords affect the marginal benefit curve for an advertiser, and why?
