Raising CPA unlocks Shopping scale

Most merchants treat CPA as a fee to cut. On Google Shopping it is the lever that sets how hard a CSS can bid. Inside the right range, a higher CPA% funds auction capacity and incremental GMV, with merchant net still rising.

  • CPA% is channel COS and the CSS bidding ceiling

  • Illustrative sweet spot 8% → 11%: traffic +35%, GMV +45%, net +40%

  • Operate in the expansion band; beyond ~14–16% net can fall

Read the full case study
Problem

Merchants negotiate CPA down and leave their CSS under-powered in Shopping auctions, treating commission as pure cost instead of auction capacity.

Intervention

Frame CPA uplift as a controlled elasticity test: raise the rate, change bidding policy in hours, prefer selective uplifts, and define stop/go on marginal GMV vs marginal COS.

Result

In the illustrative 8% → 11% sweet spot, traffic +35%, GMV +45% and merchant net +40%: both sides win when growth outpaces the commission step-up.

  • 8→11%

When EU duties looked like an impossible problem

On 1 July 2026 the EU introduced a flat €3 duty per item on low-value extra-EU parcels. Fear compressed demand before go-live; then hourly campaign governance turned the shock into a controlled landing on Google Shopping.

  • Fear hit before the duties: GMV trough on 30 June, not 1 July

  • Go-live day rebound: GMV +66% vs the previous day

  • AOV and conversion quality held steady pre vs post

Problem

Anticipatory demand crash ahead of the €3 EU low-value parcel duty: normalised GMV fell to 50 on 30 June while no duty was yet in force.

Intervention

Kept campaigns live and steered Google Shopping hour by hour with seasonality adjustment and tROAS control through the go-live window.

Result

Controlled landing: GMV rebounded +66% on 1 July vs 30 June; first-week post averages showed +8% GMV and volume, with CR and AOV essentially flat.

  • +66%
