Businesses that use AdWords can present relevant ads to searchers by using a Pay-Per-Click (PPC) Keyword list. People who then search the Web using Google search engine will trigger ads to display when they perform searches using your PPC Keywords. All search results are presented as a list. AdWords ads appear under the heading “Sponsored Links” on the right-hand side or above Google regular search results. If your AdWords ad is clicked on, Google search users are directed to your website and you are charged a small PPC fee.
