Improving Google Shopping Performance for Smyths Toys

What Did We Do?

Implementing a single product ad group strategy

Moonbow restructured the Google Shopping account using a Single Product Ad Group (SPAG) framework.

This structure allows each product to sit within its own ad group, providing much greater control over bidding strategies and optimisation decisions.

 

Phase 1 — campaign restructuring

We rebuilt the Google Shopping campaign structure to enable product-level management.

Key actions included:

  • separating individual products into dedicated ad groups
  • restructuring campaigns to improve segmentation
  • implementing manual bidding strategies for tighter control
  • prioritising key products based on commercial performance

This new structure allowed optimisation decisions to be made at the individual product level, significantly improving campaign flexibility.

Phase 2 — continuous optimisation

Once the new structure was implemented, Moonbow introduced an ongoing optimisation process to improve efficiency.

This included:

  • adjusting bids based on product performance
  • prioritising high-performing and high-margin products
  • reducing spend on underperforming listings
  • analysing search query data to refine visibility

This hands-on approach ensured advertising spend was consistently directed toward the products delivering the strongest return.
