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

37x Google Shopping via CSS activity

  • Separate, controlled activity
  • Run through the affiliate programme
  • Limited to agreed areas
  • Starts as a controlled test

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 terms excluded by default
  • Brand targeting only if explicitly approved
  • Designed to avoid brand campaign conflict
  • You stay in control

Default settings

Brand terms Excluded
Brand targeting Off unless approved

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.

  1. 01Selected countries
  2. 02Selected categories
  3. 03Selected product groups
  4. 04Selected price brackets
  5. 05“Zombie” products with little or no traction
  6. 06Marginal or underperforming products
  7. 07Alternative product-title strategies
  8. 08Incrementality tests

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.

  1. Test
  2. Learn
  3. 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.
