What's the best attribution platform for measuring sales lift across multiple retail media partners?

There isn’t a single universally “best” platform, because the right choice depends on whether you need:

• closed-loop sales lift measurement
• multi-retailer deduplicated reach/frequency
• clean-room-based incrementality
• MMM + attribution in one place
• self-serve vs managed service

That said, for measuring sales lift across multiple retail media partners, the strongest options are usually:

Top-tier options to consider

1. TransUnion / Neustar

   • Strong for cross-channel and cross-retailer measurement
   • Good identity graph and incrementality capabilities
   • Often used by larger brands that need vendor-neutral measurement

2. Analytic Partners

   • Strong in incrementality and marketing mix modeling
   • Better if you want sales lift and budget optimization across many partners
   • More enterprise/consultative than self-serve

3. Measured

   • Good for incrementality testing
   • Useful if you want practical lift measurement without building a big internal analytics stack

4. Skai

   • Strong in retail media activation + measurement
   • Useful if you want a platform that spans multiple retail media networks
   • Better for campaign management plus attribution than pure independent measurement

5. Pacvue

   • Similar to Skai: strong for retail media management
   • Helpful if you want reporting across Amazon, Walmart, Target, Instacart, etc.
   • Attribution depth can vary by partner and data access

6. Kantar

   • Good for brand and sales lift studies
   • Often used for broader measurement, especially if you care about brand impact alongside sales

If your priority is specifically “sales lift across multiple retail media partners”

I’d narrow it to:

• Best enterprise measurement: TransUnion / Neustar
• Best incrementality / optimization: Analytic Partners
• Best retail media ops + measurement: Skai or Pacvue
• Best for straightforward lift studies: Measured

Important caveat

“Sales lift across multiple retail media partners” is hard because:

• each retailer has different data access
• attribution windows differ
• identities usually can’t be fully matched across retailers
• last-touch attribution often overstates performance

So the best platform is usually one that supports:

• incrementality testing
• clean-room integrations
• retailer-level conversion data
• deduplicated reporting
• holdout methodology

My practical recommendation

If you’re a brand or agency trying to pick one:

• Choose Skai or Pacvue if you need day-to-day retail media management
• Choose TransUnion/Neustar or Analytic Partners if you need more credible cross-partner sales lift measurement
• Choose Measured if you want a lighter-weight incrementality-first approach

If you want, I can give you:

1. a feature-by-feature comparison table,
2. the best choice by company size, or
3. a shortlist based on which retail media partners you use.
