Google Ads ROAS and AOV Benchmarks

Macro-Trend Analysis: Shopping ROAS & AOV

Overall Trajectory & Performance Gaps

Current data reveals a sustained year-over-year (YoY) increase in both advertising profitability (ROAS) and consumer spending (AOV).

• AOV maintains a persistent premium over the previous year, with the gap widening significantly in Q1 (Feb–Apr).
• ROAS generally outperforms the prior year, highlighted by a massive efficiency spike in December where the current year surged while the previous year plummeted.

Metric Divergence: CAC vs. Pricing Power

A critical divergence occurs in late October through November: AOV remains elevated, yet ROAS dips below the previous year. This indicates that while retailers maintained pricing power, Customer Acquisition Costs (CAC) surged. Aggressive early-holiday auction competition and rising CPCs temporarily outpaced the revenue gains from higher order values, eroding net profitability just before peak Cyber Week.

External Drivers & Market Forces

• Inflationary Pressures: The continuous YoY rise in AOV strongly correlates with macroeconomic inflation. Retailers are passing increased supply chain and shipping costs to consumers, establishing a higher baseline for retail pricing.
• Algorithmic Bidding Maturation: The overall ROAS elevation—despite higher industry CPCs—signals the successful market penetration of AI-driven bidding strategies (e.g., Value-Based Bidding). The December ROAS spike suggests algorithms are now highly adept at identifying high-intent, high-basket shoppers during peak demand, maximizing margin rather than just conversion volume.
• Consumer Consolidation: The Q1 AOV spike, paired with volatile ROAS, suggests consumers are consolidating purchases to hit free-shipping thresholds amidst economic caution. Shoppers are buying less frequently but building larger baskets when they do convert.
