PPC, or Pay-Per-Click, is a digital marketing strategy where advertisers pay a fee whenever someone clicks on one of their online ads. This model is commonly used in search engine advertising, with advertisers bidding on specific keywords relevant to their products or services. When users search for these keywords, the ads appear prominently in search engine results. If a user clicks on the ad, the advertiser is charged a predetermined amount. PPC offers precise targeting, immediate visibility, and the ability to track and measure results. It is popular for businesses looking to drive website traffic, generate leads, or boost sales through online advertising campaigns.
