Shopify merchants can now access Microsoft Advertising’s inventory directly from their store interface, thanks to an expanded rollout of the official Microsoft Channel app.
The app is now available in France, Germany, Italy, Spain, Netherlands, Japan, Australia, and the United Kingdom, joining the existing availability in the United States and Canada.

It allows merchants to create a new Microsoft Advertising account or connect an existing one with just a few clicks.
Once linked, product feeds can be synced quickly for streamlined campaign setup and management.
