A Facebook pixel collects data about your customers’ behaviour on your page, so that you can get more information that help you enhance your marketing tools and attract new customers.


Our app works like this:

1. A master pixel added in our app will track all of the products, just like the pixel the merchant has added to Shopify. It should be different that the one you’ve added in Shopify, you risk having the tracking data doubled - so have it either here or in Shopify.


2. When the merchant adds a custom pixel to a product or a group of products, they will be tracked by that pixel - and that pixel will only track them and their events.
