Meta’s global ad marketplace is splitting into two distinct cost curves. According to new Emplifi data, retail CPCs nearly doubled from $0.16 to $0.32 over the past year, while ecommerce CPCs fell from $0.23 to $0.19 as Meta’s AI optimization drove sharper efficiencies. The overall median CPC declined from $0.19 to $0.15, indicating advertisers aren’t cutting spend—they’re reallocating as automation improves returns. Retail’s mixed online–offline goals make optimization harder, while ecommerce benefits from clearer conversion signals. With Q4 competition intensifying and holiday ecommerce projected to grow 7%, marketers should expect sharper CPC swings and plan for agile bidding, creative iteration, and real-time budget shifts.
