Additional Google Shopping sales, tested through CSS
37x funds and manages Google Shopping via CSS activity through your affiliate programme — paid on standard affiliate commission terms.
What 37x does
37x runs Google Shopping via CSS activity for your products through your existing affiliate programme. We fund the media spend, manage the testing and optimisation, and are paid only when affiliate-tracked sales are generated.

Designed to sit alongside your existing Google Shopping activity
37x is not trying to replace your in-house team, agency, or existing Google Shopping setup. The activity is separate, controlled, and run through the affiliate programme. Brand terms are excluded by default unless explicitly approved.
Your existing PPC / agency activity
- Stays as it is
- Managed by your team or agency
- Unchanged by 37x

Brand-safe by default
37x excludes your brand terms unless you explicitly say they are allowed. The aim is to test additional Google Shopping sales through CSS without interfering with existing brand activity.

- Brand targeting only if explicitly approved
- Designed to avoid brand campaign conflict
- You stay in control
Default settings
You control the boundaries
Activity can start small and stay limited to specific areas. You decide where it runs — and you can pause or stop it at any time. Limit by any combination of these; narrow or widen the scope as the tests progress.
- Country
- Category
- Product range
- Brand
- Price bracket
What 37x can test
37x can test specific parts of your catalogue rather than asking for an open-ended launch.

Test first. Scale where the data supports it.
37x starts with controlled tests. Where the data supports it, activity can scale. Where it does not, we share the findings and recommend whether to adjust or stop.
- Test
- Learn
- Scale / Adjust / Stop
- Start in a defined area
- Review performance
- Scale supported areas
- Adjust or stop weak areas
- Share clear recommendations
As testing progresses
37x shares what is being tested, what is working, what has changed, and what happens next — with a clear recommendation to scale, adjust, or stop.
