Glad you took the time to do a thorough recap, Adam. Having run many Facebook campaigns, you’ve inspired me to try the same sort of test to see if I come up with different results.

From just looking at your reach/impression numbers, I’d argue that your audience was actually too big. The CTR of around 0.50% reenforces the theory that you were underwhelming your audience. More money definitely helps, but this feels very broad overall.

I’m curious to do two different tests, so I’m wondering if you’ll help me out…

Testing your exact shirt design, but with my theories on Facebook advertising would be a very interesting apples-to-apples test. And then I plan to find my own creative niche, design my own shirt, and then run my own campaign. What do you think? Split the profits on your design?
