The right retail media representation and monetization partner is one that is open about how it sells your media, protects your shopper data, keeps the supply chain clean and gives you reporting you can check. Promised revenue matters, but it is only meaningful when you can see how it was earned. A structured set of questions, asked of every partner you consider, makes the comparison fair.

This guide is a neutral checklist. It is written so you can use it with any partner, including us.

Start with what you need

Before comparing partners, be clear about your own goals. A retailer looking for new non-endemic demand needs something different from one that wants help packaging onsite inventory for programmatic buyers. Write down:

  • Which inventory you want represented (web, app, video, offsite) and in which markets
  • Which buyers you already serve well, and which you do not reach
  • What you will keep in house, such as supplier relationships
  • Your rules on categories, competitors and shopper data

A clear brief makes it easier to spot a partner that answers the question you asked, rather than the one it prefers.

1. Transparency: can you see how your media is sold?

Media representation means a partner brings your inventory to market on your behalf. That only works if you can see what happens to it.

Questions to ask:

  • Which buyers, agencies and platforms will see our inventory?
  • Will we see buyer-level or advertiser-level reporting, or only totals?
  • How is the partner paid: revenue share, fixed fee or a mix? What exactly is the base for any share?
  • Are there any other fees, platform costs or deductions between the buyer's spend and our revenue?
  • Can we approve or block specific advertisers and categories?

A good partner answers these plainly and puts the answers in the contract.

2. Data handling: who controls your shopper data?

Retail media depends on first-party data, so this is where caution matters most.

Questions to ask:

  • What data, if any, does the partner need from us, and why?
  • Will any shopper data leave our systems? In what form (aggregated, pseudonymised, raw)?
  • Can the partner use our data for any other client or purpose? This should usually be no.
  • How long is data kept, and how is it returned or deleted when the agreement ends?
  • How does the partner support our consent and privacy obligations?

Many representation arrangements need little or no shopper-level data from the retailer at all. If a partner asks for more than its role requires, ask why. Data protection terms should always be reviewed by your own legal and privacy advisers.

3. Supply chain hygiene: ads.txt, app-ads.txt and sellers.json

Programmatic buyers rely on a few public standards to check that inventory is genuine and sold by authorized parties. A partner that is careless with these can quietly cost you demand.

  • ads.txt stands for Authorized Digital Sellers. It is a file a publisher places on its site to list the companies permitted to sell its inventory (IAB Tech Lab). app-ads.txt extends the same idea to apps distributed through app stores, including connected TV app stores (IAB Tech Lab).
  • sellers.json is published by sellers and intermediaries. IAB Tech Lab says it "enables buyers to discover who the entities are that are either direct sellers of or intermediaries in the selling of digital advertising" (IAB Tech Lab).
  • The SupplyChain object travels with a bid request and shows each party that sold or resold it. Buyers can check those parties against sellers.json files (IAB Tech Lab).

See our glossary entries for ads.txt, sellers.json and the SupplyChain object for plain-English definitions.

Questions to ask:

  • Exactly which lines will you ask us to add to ads.txt or app-ads.txt, and why is each one needed?
  • Will those lines be marked DIRECT or RESELLER, and does that match how you actually sell?
  • Is your company listed in your own sellers.json, and how will our inventory appear there?
  • Who checks our files for outdated or incorrect entries, and how often?
  • How do you detect and handle invalid traffic, meaning ad activity that is not from genuine human interest?

Example (illustrative)

A specialist outdoor retailer is comparing two partners. The first sends a list of fourteen ads.txt lines with no explanation. The second sends three lines, explains which demand each one supports and offers to review the file quarterly. The second answer is easier to verify and leaves fewer unexplained sellers on the retailer's inventory.

4. Reporting: can you check the numbers?

Questions to ask:

  • Which metrics will we see: impressions, fill rate, eCPM, viewability, revenue by deal and by buyer?
  • How often, and in what format? Can we export raw reports?
  • Will reports reconcile with our own ad server data, and who resolves differences?
  • For campaigns that use our data, how is measurement defined and shared with advertisers?
  • When will payment follow the reporting period?

Reporting you cannot reconcile is a warning sign, however good the totals look.

5. Commercial approach: how will they find demand?

Questions to ask:

  • Which types of buyers does the partner actually work with: brands, agencies, trading desks, DSPs?
  • Which deal types can they set up: direct, PMP, PG, curated packages?
  • How will they package our inventory, and will we approve packages before they go to market?
  • How will they work alongside our own sales team without competing for the same buyers?
  • Can they share relevant experience in retail media specifically, and if they are new to it, how do they plan to apply their wider experience?

That last question deserves an honest answer from any partner. Retail media is still developing, and many capable partners are relatively new to it.

6. Contract terms: what are you committing to?

Questions to ask:

  • Is the agreement exclusive? If so, for which inventory, channels and markets?
  • What is the initial term, and what notice is needed to end it?
  • Are there minimum guarantees, and what happens if they are missed on either side?
  • Who owns packages, segment definitions and data created during the agreement?
  • What happens to ads.txt entries, live deals and data when the agreement ends?

Ask your legal advisers to review the final terms. The goal is an agreement you could leave cleanly if it stopped working.

Analysis

A simple way to compare partners is to score each section above from one to five, weighted by your own priorities. A partner with modest revenue projections and full marks on transparency is often a safer choice than the reverse.
