👉 Hit math, also known as "hit-based" or "pay-per-click," is a digital advertising model where advertisers pay only when their ads are clicked, rather than when they appear in users' feeds or on a website. This model is prevalent in search engine marketing, social media platforms, and display networks. Advertisers set a budget and target specific keywords or demographics, and their ads are shown to users who click on them. The payout is typically a fixed amount per click, making it cost-effective for advertisers as they only incur expenses when their ads drive action. This model shifts the risk from the advertiser to the publisher, as they only pay for actual engagement.
