Custom conversions let you create rules for events or URLs so that you can better track and optimize for specific actions with Facebook ads.
If you have the Facebook pixel installed on your website, you can add standard events without any code using the Event Setup Tool.
The Facebook pixel helps advertisers track events that occur on their website and reach people who performed those events with ads.
Parameters can be included when tracking standard and custom events with the Facebook pixel, allowing you to provide details of an event.
Pixel events allow you to track specific actions on your website that can be used for reporting, targeting, and optimization.
