Microsoft Ads for Ecommerce: Shopping Campaigns, Product Ads, and ROAS Strategy
Most ecommerce brands run all paid search through Google. This makes sense given Google's volume advantage, but leaves meaningful revenue untapped. Microsoft Product Ads (the equivalent of Google Shopping) consistently generates incremental ecommerce revenue at CPCs 25-40% lower than Google Shopping — adding 15-25% to total paid search revenue for brands that expand to the platform.
Microsoft Product Ads: How They Work
Microsoft's Shopping format is called Product Ads. They appear as visual product listings (image, name, price, store name) in Bing search results. Setup requires:
Microsoft Merchant Center: The equivalent of Google Merchant Center. Create an account at merchantcenter.microsoft.com, verify your domain, and upload your product catalog.
Product Feed: Microsoft accepts the same format as Google Shopping (XML, CSV). If you have an optimized Google feed, it works in Microsoft with minimal changes.
Product Ad Campaigns: Once your feed is approved, create Shopping campaigns in Microsoft Ads targeting product groups from your catalog.
Feed Optimization for Microsoft Shopping
Feed quality drives Product Ad performance. The most important attributes:
Product Titles: Primary matching signal. Lead with brand + category + key attributes. Example: "Nike Air Max 270 Men's Running Shoes Black Size 10" outperforms "Men's Athletic Footwear."
GTINs: Including UPCs/GTINs for branded products significantly improves matching accuracy and can lower CPCs.
Custom Labels: Use to segment catalog by margin tier or performance level for differentiated bidding.
Remarketing for Ecommerce
Dynamic remarketing shows users the specific products they viewed. Setup requires:
- UET Tag installed on your site (tracks views, add-to-cart, purchases)
- Product viewer, cart abandoner, and purchaser audiences
- Remarketing campaigns with audience targeting and feed association
Cart abandoners and product viewers are the highest-value segments.
Performance Max in Microsoft Ads
Microsoft PMax (launched 2023) automates budget across search, shopping, and audience placements. Best for accounts with established conversion history (25+ conversions/month in Microsoft Ads). For new accounts, start with standard Product Ad campaigns to build data first.
