A piece of code that collects information about a user. When running Facebook ads, you install a pixel on the website to track anyone who visited a specific product page, generally visited the website/homepage, or any other of your custom conversions. You can go into FB Ads and retarget people who have, for example, been on your website in the last 180 days.
