PPC is a type of Internet marketing in which the advertiser pays a charge whenever their ad is clicked on a search page. PPC advertising offers a cost-effective way to boost an online advertisement presence while still netting a considerable profit.
When a user searches something on Google, AdWords will pull all the ads which keywords match that particular search. From the ads, any that aren’t eligible, such as ads that target a different country or that aren’t relevant, will be ignored. From the ads remaining, only those with a high enough Ad Rank will show results.
PPC is an online advertising channel in which advertisers pay each time a user clicks on one of their online ads.
