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.
