In addition to the myriad of methods Facebook (now Meta) uses to track you while using their social networking platform, the company also has a variety of ways to track you even when you’re on another website. Now, a new study is trying to combat Facebook’s tracking tools by… tracking them back.

In exchange for the free Facebook pixel integration on their websites, these sites can then track visitors and direct ads with the same precision you’d expect from a company like Facebook.

On the other hand, by giving websites the ability to track every page view, purchase, search query, and more, Facebook naturally requires this data to be shared with them as well.
