How the Facebook pixel works
When someone visits your website and takes an action (for example, buying something), the Facebook pixel is triggered and reports this action. This way, you'll know when a customer took an action after seeing your Facebook ad. You'll also be able to reach this customer again by using a custom audience. When more and more conversions happen on your website, Facebook gets better at delivering your ads to people who are more likely to take certain actions. This is called conversion optimization.
Once we had Facebook conversion tracking in place and started using Custom Audiences, we saw a huge uplift in sales. Facebook ads became ROI-positive for us, from day one!
