PPC is an abbreviation for "Pay Per Click". It is a model of online advertising where advertisers pay a fee each time one of their ads is clicked.
PPC is a popular advertising model because it allows advertisers to target their ads to a specific audience, and only pay when their ad is clicked. This makes it a very cost-effective way to reach potential customers.
Auditors may use PPC to refer to the process of auditing pay-per-click advertising campaigns. This type of audit can help ensure that an advertiser is getting the most bang for their buck, and that their ads are being seen by the right people.
