Hey ppz,
I've made good bank on Teespring in the last 2 months and now I want to start expanding into other niches. So for this campaign I'm going w/ Basketball. Targeting fans of a team and fans of players on that team. Campaigns are split by objective so I have one for website conversions and one for post engagement. Ad sets are split by City Only vs. State vs. Country. I'm also testing fans of superstar players vs. fans of less known player vs. Team fans. I'm starting out with 1 ad which is a fan page post w/ cloaked teespring link. For some reason these convert the best for me. I think it has to do with the fact that it doesn't look like an ad at all. I'm running mobile and desktop newsfeed only.
Budget is oCPM $20/day to start. When sales start coming in I'll increase the budget throughout the day.
Profit per shirt is around $10 with a goal of 50.
I haven't done many follow alongs, you guys need any other info to start?
What if i provide you with tons of ad account and funding.
Can, we split some profit %
Be careful with that...if the marketing/legal department of that team finds out you may get sued.
I don't think he'll get sued, 99.9% C&D unless he is using actual logos and doing a lot of volume with just that one campaign.
Thanks for the tips guys. I'm not infringing on this one. It doesn't use the team name or the logo. That said I think my design may be bad. Here's a few screenshots after running since yesterday when I made the first post:
Campaign is by conversions
First row is all fans of team players targeting the Entire US
Second row is All fans of team in city of team

Campaign is by post engagements
First row is by All US / Team Fans
Second row is by team fans in city of team

I usually kill any ads under 4% CTR after 1000 impressions/no conversions when going to newsfeed.
Initial thoughts:
I might want to scrap this one as there are no sales yet, but plenty of people have clicked through.
I may create a dark post that includes the price on the ad so people know the price before they click through.
The shirt is simply too expensive @ $19
Is page post engagement a viable way to do this? How many actual clicks leading out of facebook does that get you because I feel like page post engagement is good for getting people to stay within facebook and be active, although I guess you do get the benefit of social proofing your ad and having a ton of shares and stuff and increasing the reach organically? 
What is the reason for cloaking the link? I thought this wasn't necessary unless you were using custom audiences or were calling out names in the ad.
hey, how you doing?
I still see plenty of naming campaigns? how these guys are doing it. I've heard facebook doesn't allow this anymore.
It's a straight newsfeed ad with direct teespring link, no cloaking, nothing. How's he getting them approved?
