Facebook Interest Targeting Hack

Which interest is working?

If you’ve ever set up a successful Facebook ad then you’ll know how good it feels. Some people stumble on a winning ad on their first try, others take hundreds of attempts. Don’t beat yourself up if you can’t get it right, it’s not easy! The chances are though that if you’ve started Facebook ads from scratch, you’ve set up some basic targeting like age, gender and location and then added some interests that match your niche. That’s great, and a good way to see how well your audience react to your product/service. If you’re lucky, it will bring some results in the form of engagement, clicks and SALES! But say you used 5 interests for your targeting, how do you know which one is the one that was the best performer? You either spend more money by creating new ad sets with only 1 of each interest in and see which works best or you keep spend money on your multiple interest ad set meaning you still may be wasting money on an interest that isn’t performing.

Here’s the hack:

  • Set up a custom audience of people who engaged with your ad
  • In power editor set up a new ad and select the new custom audience
  • Let’s say this audience is 100,000 people
  • 1 by 1, add each interest that was in the initial ad set on top of your custom audience
  • This shows you approximately how many people who engaged with your ad fall under each interest.

So if interests 1 takes the reach from 100,000 to 50,000 then it’s probably a good interest to target. But if interest 2 takes the reach from 100,000 to 1,000 then not that many people fall under that interest. It might be an idea to drop that one from your targeting.

It’s not perfect and it only helps you to narrow your interest targeting down to an extent, but it could save you £$£$ in the long run!
