Facebook Pixel collects information about visitors to your store, so you can precisely define ads for them. Advertising becomes cheaper when you know who has been, is and can be your customer. You can target ads to those who have already bought in your store, those who have looked at the store page, but also to those who have similar interests as your customers.
If you are not advertising on Facebook, it is also worth activating the Facebook Pixel, as data is collected from the moment of installation and you can use it in the future.
If you don't have a Facebook Pixel, find out how to create one: Creating a Facebook Pixel
In the admin panel, select Applications → Facebook Pixel
This allows you to target ads to people who visit specific products in your store.
Thanks to this option, you can reach customers who have added a product to the cart but have not completed the purchase.
This option allows you to monitor purchases. This makes it easier to reach your regular customers.
