👉 Ad math, or advertising math, is a set of mathematical techniques used by advertisers and marketers to optimize ad spend and maximize return on investment (ROI). It involves applying principles from probability, statistics, and optimization to determine the most effective allocation of advertising budgets across different channels, audiences, and campaigns. By analyzing data on consumer behavior, market trends, and ad performance, advertisers use ad math to calculate the optimal price-to-benefit ratio for each ad placement, ensuring that they reach the right audience at the right time while minimizing waste and maximizing revenue. This approach helps businesses achieve better campaign efficiency, higher conversion rates, and ultimately, improved profitability.
