Finish off the Test Interests action by selecting an ad from your Ads Manager to start your testing. Once you press submit, this campaign that contains the number of ad sets you've created in the step before will be created. From here, it's up to you to check whether those ad sets are performing well or not.
Remember: Facebook Advertising is all about testing!
How to get your support tickets resolved faster
Statistics have shown us that the more you tell us when you report an issue, the faster we solve that ticket. So...
1 - If you have screengrabs, please include them. A picture is worth a thousand words.
2 - If you have recorded a video showing the issue you're having, please include that as well. A video is worth a million words. We recommend a free service called Loom for creating these videos. (this is a link to use loom.com)
