I have profitably spent hundreds of thousands of dollars on Facebook ads. I have been doing this heavily since 2016. I could attribute most of my basic learning to Travis’s free resources that he put up on YouTube.
If you’re interested in Facebook advertising, I recommend that you complete these tutorials. You should also go through these.
Travis has been playing this game for over a decade so he’s pretty good at what he does. Much of his content may be dated although still very useful. This is still my favorite resource for getting the basics right.
For intermediate strategies, I’d recommend that you check out Verum. To understand what he’s saying, you need to be well aware of basics. If you’re well aware of the basics, you’d love his content and find it very easy to digest. Otherwise you probably wouldn’t understand much of what he’s saying.
The most advanced players, however, are the AdLeakers. I don’t think there’s any value for anyone here unless he’s already spending a lot of ad budget profitably and wants to further up his game by working on cost reduction strategies to achieve lower cost per acquisitions.
I don’t suggest that you invest in any course if you’re just starting. Investing in the actual ad budget might be a much better idea. But before you even do that, I strongly recommend that you consume Travis’s KingPinning tutorials.
