A Pay-Per-Click (PPC) campaign is an internet advertising model in which advertiser’s pay a fee each time one of his ads is clicked and the traffic is diverted to his website. PPC is commonly associated with first-tier search engines (Google, Bing), Social Media sites like Facebook, Twitter and Linked. Advertisers also provide another format of ads, namely the Cost per 1000 Impressions (CPM) campaign where the banner advertisement is done and the advertiser pays everytime the ad covers 1000 impressions. In the case of search engines, there is a bidding process where advertisers bid on the keywords and phrases most relevant to their product or target audience. Websites, on the other hand, usually charge a fixed rate for each click on an ad published on their site or host CPM campaigns.
