Multi-brand retailers run one Shopify store but sell many brands, and Meta sees only a generic Purchase event, so it optimises for any buyer. When you want to grow one brand specifically, there is no way to tell Meta which purchases count. Plytix already holds your brand attribution. Littledata carries it into the conversion signal, so Meta trains on buyers of the brand you actually want to grow.

Create a new event based on the Purchase event and configured on the Plytix brand metafield. This event fires only when an order contains products from your target brand.

Set the new event as your campaign's optimisation goal, and Meta builds its audience model on buyers of your target brand instead of all purchasers.
Plytix syncs brand attribution to Shopify as metafields and Littledata can read and turn it into a brand-specific conversion signal.
