Dynamic Retargeting for E-commerce
Dynamic retargeting automatically shows each individual visitor an ad featuring the specific products they viewed on your site - personalized at scale. Instead of creating separate ads for every product in your catalog, dynamic retargeting uses your product feed and the visitor's browsing data to generate personalized ads automatically. It consistently delivers the highest ROAS of any retargeting campaign type for e-commerce.
How Dynamic Retargeting Works
- The mechanism: When a visitor views Product A on your site, the pixel fires a ViewContent event with Product A's ID. When that visitor is later served an ad, the platform automatically pulls Product A's image, name, and price from your product catalog and inserts them into a dynamic ad template.
- Product catalog: The source of truth for dynamic ads. Must be connected to both Meta Ads and Google Ads. For Shopify, the Meta/Google product catalog syncs automatically via app integration.
- Meta Dynamic Product Ads setup: Upload product catalog to Meta Commerce Manager → Create Catalog Sales campaign in Ads Manager → Create ad set targeting website visitors (ViewContent, AddToCart events) → Select catalog in ad creation → Meta populates ads automatically from catalog.
- Catalog feed requirements: Product title, description, image URL (minimum 500×500px), product URL, price, currency, availability, product ID, category. Optional: sale price, brand, condition, GTIN.
Dynamic Retargeting Campaign Segments
- Viewed product, didn't add to cart: Show the product they viewed + related products. Message: 'Still interested in [Product]? Here's what other customers think...' Include a testimonial or rating.
- Added to cart, didn't purchase: Show the specific carted product with more urgency. 'Your cart expires soon.' or 'Only 2 left in stock.' Add a discount only in the final follow-up (Email 3 of your abandoned cart sequence).
- Purchased, recommend complementary: If someone bought Product A, show them Product B from the same category. 'Customers who bought [A] also love [B].' This is upsell/cross-sell retargeting.
- Viewed but never carted (30+ days ago): Show a broader category ad rather than the specific product. Products they might have forgotten about but still need.
