Retail media: the third wave of online advertising

After search and social, retail media stands as the third advertising pillar. What to expect from it.

In short:

  1. Retail media surpasses TV advertising in investment in several European markets.
  2. Retailers’ transactional data offers targeting unavailable elsewhere.
  3. The lever remains under-used by brands outside consumer goods.

Retail media, advertising on retailers’ sites and apps, has become the third pillar of online advertising, behind search and social.

Why it is rising

  • End of third-party cookies: retailers’ first-party data becomes strategic
  • Proximity to purchase: the ad shows at decision time
  • Closed-loop measurement: impression, click and sale in the same ecosystem

Who should go

Brands sold through retail first. But marketplaces open the lever to almost every e-merchant.

Where to start

A test on a flagship range, a framed budget and an honest read of incrementality. The audit reflexes remain the same as on Google Ads.
