Paid search follows a Pay Per Click, or PPC, advertising model. Using this system, an advertiser only pays when a consumer clicks on their delivered ad.

This statement is true. Pay-Per-Click (PPC) is the fundamental advertising model used in paid search. Advertisers bid on keywords, and their ads are displayed to users searching for those terms. The advertiser is only charged a fee when a user actively clicks on their ad, leading them to the advertiser's website or landing page. This model ensures that advertisers pay only for engaged traffic, making it a cost-effective and measurable form of advertising. If a user sees the ad but doesn't click, the advertiser incurs no cost.
