Linking by Collections
Collection-based linking is the most popular and efficient way to associate size recommendation quizzes with products in SmartSize AI Fit Recommender. By linking to Shopify collections, you can automatically include all products in a collection and any products added to the collection in the future.
What is Collection Linking?
Collection linking associates your quiz with entire Shopify collections rather than individual products. When a customer visits any product page for a product in the linked collection, SmartSize AI Fit Recommender displays your quiz.
How Collection Linking Works
Automatic Association:
- Link quiz to one or more Shopify collections
- All products in those collections automatically get the quiz
- New products added to collections automatically get the quiz
- Products removed from collections automatically lose the quiz
Dynamic Updates:
- No manual product management required
- Collection changes reflect immediately
- Scales automatically with your product catalog

Collection Condition Logic
ANY Condition (Recommended)
How it works: Quiz displays if product is in any of the selected collections.
Example:
Selected Collections: "Summer Dresses", "Evening Wear", "Formal Attire"

Best for:
- Broad product coverage
