New thing: Shopify Product Network - Now shoppers who have the Shop App will get recommended products from merchants, optimized for "conversions and purchase likelihood", and the original merchant you were searching in gets a kickback if you buy something from another merchant, which incentivizes more merchants to participate.

Essentially: If a person searches for "red shoes" on a specific merchant's website and that merchant doesn't have red shoes, the SPN shows them "red shoes" from another Shopify merchant directly in the search results.

They're saying it's not ads, but kind of like ads (they call it "merchandising"). But whatever the product results are called, it's clearly an effort to get people to search for products in the Shopify ecosystem of merchants rather than on search engines.
