Topsort Offsite Ads

Topsort Offsite Ads enables marketplaces to launch vendor-funded advertising campaigns across advertising platforms like Google, Meta, TikTok, Snapchat, Universal Ads, and OpenAI. With one unified campaign flow, marketplaces can let vendors promote their products offsite using catalog SKUs, uploaded creative assets, or both. Vendors create campaigns in Topsort, ads run on advertising platforms, and shoppers are driven back to the marketplace to generate incremental GMV. Marketplaces can use the Topsort UI or build their own experience on top of the Topsort Offsite API. All core UI functionality is available via API.

Why run offsite ads with Topsort?

Instead of managing separate advertising programs directly across Google, Meta, TikTok, Universal Ads, and other advertising platforms, Topsort gives marketplaces a unified way to operate, attribute, and scale offsite retail media.

Self-service campaign creation

Vendors can create offsite campaigns through a familiar Topsort experience, using the same wallet, billing, and campaign-management patterns they already use for onsite ads. Topsort supports both prepay and postpay billing models. For campaigns using uploaded creative assets, marketplaces can also enable an ad-ops approval flow before campaigns go live. This helps marketplaces scale offsite advertising without scaling manual operations at the same pace.

Marketplace-owned attribution

Topsort’s in-house attribution lets marketplaces apply the same attribution window and configuration across supported advertising platforms for apples-to-apples sales and ROAS comparisons. Marketplaces can also use reporting retrieved from an advertising platform, based on that advertising platform’s attribution methodology. See Attribution and Billing for details.

Less integration complexity

Running offsite campaigns directly often requires separate integrations, setup processes, and catalog-management workflows for each advertising platform. Topsort simplifies this by guiding marketplaces through the setup process for each supported channel, including catalog syncing where required.

Unified multi-channel execution

Marketplaces and vendors can create campaigns across multiple offsite channels and formats from a single Topsort flow, instead of rebuilding the same campaign across separate advertising platforms.
