If you sell bundled products, you can add these to your product recommendations in the same way as simple products.
Understand bundled products
The product recommendation engine uses treats bundled products in the same way as simple products. However, you can only filter your recommendations by the top-level product and not individual items within a product bundle.
This is also the same when using our machine-learning-powered product recommendations — they only use data from the bundle, not the items in the bundle.
