Overview

Retail media has become the third-largest category of digital advertising — and purchase decisions increasingly get made right on the product listing. We manage Amazon, Walmart Connect, and local marketplace advertising as a full performance channel.

Our team pairs media buying with listing optimization itself — content, images, and ratings — because no amount of advertising saves a weak listing.

What's included

  • Amazon Ads management (Sponsored Products, Brands, Display)
  • Walmart Connect and local retail media networks
  • Product listing optimization and marketplace SEO
  • Review and rating management
  • Reporting on share of shelf and revenue
