What is Meta Pixel (formerly Facebook Pixel)? How does it work?

Meta Pixel is a small snippet of code that you place on your website to collect data. When this is added to your website you can track conversions from Meta ads, optimize these ads, build out a targeted audience for future ads, and remarket to people who have already taken some kind of action on your website.

One great example of Meta Pixels' remarketing capability is if you are browsing for a product on a website and add it to your cart. Meta Pixel will place and trigger cookies to track users as they interact with your business both on and off Facebook and Instagram so with the product added to your cart, ads will pop up redirecting you to complete the purchase (ads or 'sponsored posts' can also have discounts noted).
