Pay-per-click (PPC) is a type of online advertising where advertisers pay for each click on their ads. PPC ads are typically displayed on search engines, social media platforms, and other websites. When someone clicks on a PPC ad, the advertiser is charged a fee, hence the name "pay-per-click."

PPC ads can take a variety of formats, including text, images, and videos. Advertisers bid on specific keywords or phrases relevant to their product or service, and their ads are displayed when someone searches for those keywords or phrases. The ad's placement is determined by a variety of factors, including the bid amount, ad relevance, and quality score.

One of the key benefits of Pay-Per-Click (PPC) advertising is that advertisers can reach a highly targeted audience. Pay-per-click (PPC) platforms offer a variety of targeting options, such as location, demographics, and interests, which can be used to ensure that ads are displayed to the right people at the right time.
