Choosing this simple pixel type allows you to manage fewer pixels and gives more flexibility when embedding them.

The Conversion and remarketing pixel is the correct answer because it combines the functionalities of both pixel types into a single, unified pixel. This reduces the number of distinct pixels you need to manage on your website, simplifying implementation and maintenance. It also offers greater flexibility as it can be configured to track both conversions (e.g., purchases, sign-ups) and user behavior for remarketing purposes (e.g., website visits, product views) from a single code snippet. A Remarketing pixel alone only tracks user behavior for remarketing, and a Conversion pixel alone only tracks conversions, requiring separate implementations for each.
