Retail media advertising: a guide for brands
Retail media advertising lets brands pay retailers to show their products and messages to shoppers on the retailer's sites, apps, stores and audiences. Brands choose formats such as sponsored products, display and supplier-funded offers, target by search intent, category and audience, and judge results on incremental sales rather than attributed sales alone.
Why brands buy retail media
Retail media reaches people while they shop, on the retailer where the product is actually sold. A brand can show a product to someone searching the category, and the retailer can report whether that person bought it. That combination of intent and measurable sales is why brands move budget into it from other channels.
Where the budget comes from
Brands typically fund retail media from three places: performance marketing, brand marketing and trade spend (money traditionally used for discounts, ranging and in-store promotion). Knowing which budget pays for a campaign decides how it should be judged — a brand campaign shouldn't be held to the same short-term return as a performance one. See retail media vs trade marketing.
Formats brands use
- Sponsored products in search, category and recommendations, usually per click. See how sponsored products work.
- Display, video and rich media for launches and awareness, usually per thousand impressions.
- Sponsored brand pages — a branded, shoppable destination on the retailer. See Sponsored Brand Pages.
- Supplier-funded offers where the discount itself is the ad. See Trade Media.
- Retargeting of shoppers who searched or browsed the category. See Search Retargeting.
- AI assistant placements inside shopping chat. See Sponsored Prompts.
Targeting
Targeting options usually include search keywords, meaning-based matching of the query to the product (so "school lunch snacks" can match a product never tagged with those words), category and product-page context, audience segments built from purchase history, and the stage of the visit (search, product page, basket, checkout). Meaning-based matching tends to reach more relevant searches than keyword lists alone. See run AI ads without keywords.
Bidding and budgets
Most sponsored product auctions are cost-per-click with a minimum price set by the retailer. Some retailers offer target return on ad spend (tROAS) bidding, where the system adjusts bids to a return goal. See what is tROAS. Spread budget across the flight, watch pacing, and keep a share for testing new formats.
Judging results: ROAS vs incrementality
Return on ad spend (ROAS) divides attributed sales by spend. It is easy to report but includes sales that would have happened anyway, especially for a brand's loyal buyers. Incrementality compares people who saw the ad with a holdout group who didn't, and reports only the extra sales. Ask retailers for incrementality tests on meaningful campaigns. See the retail media measurement guide.
Also look at brand halo (sales of the brand's other products), new-to-brand buyers, and share of category.
Choosing where to spend
Compare retailers on: how many of your category's shoppers they reach, how ads are ranked (relevance-ranked placements usually convert better than fixed slots that ignore fit), the quality of measurement, self-service and reporting, and whether stock and price are live so you don't pay for clicks on unavailable products.
Working with the retailer
The retailer's ad business sets floors, caps and terms and decides how under-delivery is handled. Agree in advance how you'll be notified about pacing and what happens if a campaign falls short.

How Particular Audience does it
Frequently asked questions
Is retail media advertising worth it for small brands?
Often, because sponsored products can be bought on small budgets per click and target shoppers already searching the category.
What is a good ROAS for retail media?
It varies by category, margin and whether the shopper would have bought anyway. Incrementality is a better guide than a single ROAS number.
Do I need keywords to run retail media ads?
Not always. Meaning-based matching can connect searches to relevant products without a keyword list, alongside any keywords you choose.
