PPC Pay-Per-Click (PPC) is one of methods of online paid advertising where an advertiser pays only the cost of a click on his ad and is a guaranteed method to bringing targeted visitors. Generally it is more effective than “PAY-PER-IMPRESSION” method (in this case the advertiser pays the cost of the appearance of his advertisement whether the visitor clicked on his ad or not), Also advertising budget may be drained to a large extent without any real result of the advertising.
