Offsite Advertising

Extend your retail media
demand across the internet.

Run commerce-native advertising across Google, Meta, TikTok, and other performance channels using the same auction and demand infrastructure that powers your marketplace.

Brands and retailers collaborate on bidding to drive high-intent shoppers back to your platform.

Commerce demand doesn't only
exist on your platform.

Shoppers discover products through search engines, social platforms, and external media. Topsort Offsite allows retailers and marketplaces to extend their retail media demand across these channels while maintaining control of campaigns, budgets, and attribution.

Collaborative Bidding

Retailers and brands
bid together.

Traditional advertising often forces brands and retailers to compete against each other in auctions. Topsort Offsite introduces collaborative bidding, allowing retailer and brand budgets to work together to win high-value placements.

This improves auction competitiveness while maintaining campaign transparency.

Commerce-Native Product Ads

Ads generated directly from
the commerce catalog.

Campaigns use the retailer's product catalog to automatically generate product-based ad creatives. This allows brands to launch campaigns quickly without requiring manual creative development.

Ads link directly to product pages on the retailer's platform, creating a seamless path to purchase.
