Ecommerce Advertising: What Drives the Numbers
Ecommerce advertising is the highest-volume digital ad vertical globally, driven by Google Shopping, Meta catalog ads, and retargeting across display and social. The defining characteristic of ecommerce advertising is Q4 concentration: Black Friday/Cyber Monday and the Christmas period account for 30–40% of annual revenue for most online retailers.
Channel strategy matters enormously. Google Shopping drives the lowest CPC ($0.45–$0.90) for transactional intent — users searching to buy — while Meta excels at retargeting cart abandoners and acquiring new customers via lookalike audiences. TikTok Shop is an emerging acquisition channel, particularly for impulse-purchase categories (beauty, fashion, gadgets).
Margin structure determines what CPA and ROAS targets are achievable. At 25% gross margin, break-even ROAS is 4.0×. At 40% gross margin, it drops to 2.5×. Advertisers who set ROAS targets without anchoring to margin often over-optimize for ROAS while actually operating below break-even in real profit terms.
