How do you drive traffic with an Interest List? Well, you have to create an Interest List that others will find valuable...or interesting. For the purposes of our example, you would invest the effort searching Facebook to find great sources of fitness equipment and apparel related content and information, and create an Interest List for the topic. Of course, you also want to include your own Facebook Page or profile on that Interest List.
If you curate the content to ensure the pages and profiles included in your Interest List provide value for people, and not just a bunch of noise and clutter to sort through, the Interest List will be popular with the target audience, and more people will subscribe to it. The more people subscribe to the list, the more people will also be subscribing to or following your own content as well.
I can't stress enough, though, that this isn't a cheat or shortcut to delivering quality content. You might lure some people by just creating a list that appears to be about a given topic, but if the list is not comprised of worthwhile content, and if your own content isn't useful or interesting, people will simply unsubscribe and move on.
Done right, a Facebook Interest List can be a way for you to demonstrate knowledge and build trust with your target audience, and in the process you can also build your own following with Facebook users.
