Facebook marketing is an amazing tool. For example: you’re looking for a new pair of running shoes. You do a quick Google search on the best running shoes that came out this year. The first link brings you to a website for some really great running shoes. They’re stylish, have great reviews, and seem like they’ll meet your needs. But you aren’t ready to pull the trigger and buy them just yet so you close out the tab and go about your day.
All of sudden, two weeks later, those running shoes pop up on your Facebook feed. How did they know you were looking for running shoes? How did they know you had looked at those PARTICULAR running shoes?
