I was doing a dating camp, It was very late and my brain was tired. I got a crazy idea and tried it on a whim. I targeted people in relationships. I used an ad copy similar to this "Have a bad girlfriend? Click here and browse profiles of single girls in your area. Your girlfriend's probably cheating anyways" Great response lol my ctr was awesome, at one point one was at 4%, but they all settled around .5% So I got clicks pretty cheap, about $.02 and it was actually performing traffic so it was profitable hahaha This kinda blew my mind and Ive been laughing ever since. Maybe its a common tactic I just didnt know about, but I just recently picked up dating and got a kick out of this. I think its a great example of when it pays to think outside the box. I thought this might motivate you guys to be more exploratory with your niche/method.
