Decision Framework: Where to Invest First

For New Retail Media Advertisers

Start with Amazon if:

  • You have established marketplace presence and sales velocity
  • Your category shows strong Amazon customer demand
  • You need immediate scale and performance predictability
  • Your team has limited bandwidth for multi-platform management

Start with retail media networks if:

  • Amazon competition makes efficient scaling difficult
  • Your products align strongly with specific retailer demographics
  • You have significant physical retail distribution
  • Your category performs poorly on Amazon (grocery, automotive, etc.)

For Experienced Amazon Advertisers

Expand to retail media networks if:

  • Amazon ROAS has plateaued despite optimization efforts
  • Customer acquisition costs are rising on Amazon
  • You want to reduce platform dependency risk
  • Retail partners request advertising support

Double down on Amazon if:

  • You haven't fully utilized advanced targeting and campaign types
  • International marketplace opportunities remain untapped
  • Your brand lacks organic visibility and ranking
  • Amazon's new advertising products align with your objectives

Conclusion

The choice between Amazon advertising and retail media networks isn't binary—it's about optimal allocation based on brand objectives, category dynamics, and performance requirements. Amazon provides unmatched scale and sophisticated targeting, while retail media networks offer diversification and often superior cost efficiency.

Most brands should start with Amazon mastery before significant retail media expansion. Once Amazon performance is optimized and scaled, retail media networks provide crucial diversification and incremental reach opportunities.

The winning strategy combines Amazon's scale advantages with retail media's unique targeting and measurement capabilities. Brands that treat this as a portfolio optimization challenge rather than a platform competition consistently achieve superior performance across the entire retail media ecosystem.
