Remarketing through Facebook means showing ads on Facebook to people who have previously been on your site. It used to be that you had to use a third party company on the Facebook Exchange to buy those ad placements (for example, AdRoll was a big one), but now you can do it easily yourself!
3 Easy Steps to Remarketing on Facebook
1. Go to audiences and create a custom audience
2. This will give you a pixel, which you can put in the Head section of your site, or upload easily with Google Tag Manager.
3. When you create a new ad, under the Audience section you will be able to pick custom audiences you previously made, or create a new custom audience.
