What is the name of the code that needs to be included in your website's header to track conversions?

The correct answer, "Pixel," refers to a specific piece of code that must be added to the header of a website in order to track conversions and other user interactions effectively. This code is essential for Facebook’s tracking system, known as the Facebook Pixel. When integrated, it helps advertisers monitor and optimize their ad campaigns by collecting data on how users interact with their website after viewing or clicking on their Facebook ads. The Pixel can also facilitate retargeting strategies by allowing businesses to reach users who have previously visited their website.

While "Tracking Pixel," "Facebook Tag," and "Conversion Code" may sound relevant, they do not accurately represent the standardized term that Facebook uses for its tracking mechanism. The Facebook Pixel is a specific technology that encompasses various capabilities, including event tracking, conversion tracking, and audience building, which are crucial for effective digital marketing campaigns on the Facebook platform.
