Macro-Trend Analysis: ROAS & AOV

Overall Trajectory & YoY Gaps

Over the 365-day period, both Median ROAS and AOV consistently outperform the previous year. The ROAS gap widens most significantly during the Q4 holiday shopping peak (Nov–Dec) and late Q1 (Feb–Mar). AOV follows a similar upward trajectory, indicating that consumers are tolerating higher price points while advertisers simultaneously achieve greater profitability.

Metric Divergence: CAC vs. Pricing Power

Two distinct divergences reveal shifting market dynamics:

• Summer Volume Push (June–July): AOV dips below the previous year, yet ROAS rises. This suggests aggressive summer promotional periods where discounted pricing lowered basket sizes, but the resulting surge in conversion rates drove overall profitability up.
• Pre-Holiday Squeeze (October): AOV remains elevated, but ROAS briefly drops below the previous year. This highlights rising Customer Acquisition Costs (CAC). Retailers maintained pricing power, but platform CPCs surged as competitors aggressively bid to capture early holiday intent and build audience pools.

External Drivers & Market Forces

The sustained YoY growth in both metrics points to distinct macroeconomic and platform drivers:

• Inflationary Pricing: The steady rise in AOV (peaking near 100 in Q1) reflects retailers successfully passing increased supply chain and operational costs onto consumers. Despite economic caution, baseline consumer spending power remains resilient.
• Algorithmic Efficiency: Achieving higher ROAS alongside higher AOV strongly indicates the maturation of AI-driven campaign types and the widespread adoption of Value-Based Bidding (VBB). Bidding algorithms are increasingly adept at identifying high-intent users willing to convert at premium price points, maximizing return and offsetting rising baseline CPCs.
