How does the auto recommendation work?
✔️ What is an automatic offer?
Automatic offer - an option that allows merchants to automatically display product recommendations to customers immediately after a purchase. This offer is based on the items in the customer's cart and displays products related to items in cart.
Example: when a customer buys a bike, the app may automatically suggest a bike helmet as a post-purchase upsell - though this depends on several factors.
Shopify has its own built-in functionality for determining recommendations, and ReSell relies on this functionality for Automatic offers.

✔️ How Shopify recommendations work
There are two types of recommendations:
- Related recommendations - the platform offers a mix of products that are similar or complementary to a product the customer is interacting with. These recommendations are generated automatically by Shopify.
- Complementary recommendations - Shopify offers products that complement a specific product the customer is interacting with. These recommendations need to be manually set up.
You can set up both types of recommendations for free in the Shopify Search & Discovery app.

✔️ Recommendation logic
Recommendation logic is based on: purchase history, product description, and related collections.
- Purchase history - Finds products that have historically been purchased together.
- Product description - Finds products with similar descriptions.
- Related collections - Finds products from collections that the current product is part of, excluding collections with handles all and frontpage.
