What is PPC?
PPC (Pa-Per-Click) is when you pay a fee once a user clicks an ad. PPC is commonly associated with search engine advertising. Search engines such as Google and Bing charge you for clicks. For example, when a user performs a search, and your ad appears, you will only be charged if the user clicks on your ad. The impression you get for the ad is free. The cost for the click will be charged on an auction-based model; the higher you bid, the higher the chances are for you to appear at the top of the results (other factors affect the top position, too) and you must not forget that you will be charged more too.
