I haven't given much to this forum lately, but I promise I'll share some more nuggets in weeks to come.
What's awesome about this case study is that I can't remember all the stats, kws, ad text etc. My old account was banned and I don't have that data. This way, if you want to copy and paste it, you're going to have to fill in the gaps and do a little work. 
I ran a lot of dating apps on FB earlier this year. While it can be easy going international, there is money to made in niches on FB. What I mean by that is breaking down women (zing!) into different categories based on interests and where they hang out, what they're into, etc.
This is my Emo/Punk campaign I ran partnered with a dating app that I found to convert well with this angle. I tried plenty, trust me. Some converted decent and some not at all. So if you find you run traffic to an offer and it doesn't convert, sometimes it's not always on you (but usually it is).
I think the key to this is finding what kind of women guys lust after. I always thought girls with tats and nose rings were kind of sexy (mind you sub 130 lbs). So I scoured the interweb for images of "Suicide Girls" type pics plopped them in little 110x80 boxes and played with saturation and sharpness filters to make them stand out a little more.
Here's some examples:

I think you get the general idea.
Now I had to get my targeting down. I went with interests and keywords that the Suicide girl crowd might like. By the way if you dont know what I'm talking about with Suicide Girls, no I don't mean girls killing themselves. Just have a gander http://suicidegirls.com/
I targeted keywords like "Suicide girls" "Gods girls" "social distortion" "sailor jerry" (<-- very good rum by the way) "tattoos" "burning angel" etc etc etc
Basically target as much as you can and do research if you don't know that demographic. I kind of had a general idea of what that crowd likes, does, and what kind of music they listen to. Eventually I had to do some searching and gathered a list of punk bands I've never heard of but turned out to have a ton of 'likes' on FB. It was well worth the time and effort.
My demo got up to around 400k single guys between 22-35 (I think). It doesn't really matter honestly - as long as the offer accepts the ages. Keep it weird don't think about it too much and just launch. Do whatever gets you the most volume.
For ad text, I kept it simple. They were similar to the following:
"Want a Punk Girlfriend?"
"Like Punk Girls?"
"Meet Punk Girls"
Again, don't over think it. The body copy was about the same.
"Meet the hottest punk girls ready to date. Click here to sign up!"
If you're going to run your own niche dating campaign, just highlight who the girls are, let them know they're single and give a call to action.
Did I use a lander? Yes I did. This was a must if you ask me. For niches, you almost have to presell the offer and tell them exactly how to meet the person you are promising. Now, I did cloak to another PG offer like singlesnet or true for the facebook reviewers. That doesn't mean I ran adult - I knew my lander would probably not get accepted nor would the Flirt apps (which I tested, you'll see in the lander).
Here's some screenshots of the landers. They were all made with photoshop and wysiwyg web builder.
Example 1: Lander showing a screenshot of the offer (can be any offer really)

Example 2: One showing an app with instructions. When they clicked 'Allow' they were basically sent to the app where, yes, they had to click 'Allow' again. I had some AMs tell me that it was weird sending the user away from Facebook for a lander and then back to Facebook for the dating app, but it worked just fine. So never assume.

That's basically it. The offer I eventually ended up running was an app that I got to convert around 20% with a lander. My epcs were up to .40 I can't really remember but they were damn good for .10 clicks.
Soon after the offer ran out of budget and was pulled. I was told the quality was fine, but the advertiser was just having some problems.
If you ever get an idea write it down and launch it when you can. Carry a notebook or notepad around with you always. It's valuable when a fleeting angle or campaign idea pops up in your head.
Awesome landers! Reminds me of a similar one I did last year targeting guys who like tattoos and motorcycles . The advertiser didn't like the traffic to much. Should have switched the offer for a more risque offer like you did.

Awesome angle, and even better landers!
The 'punk rock allstar' logo really makes it look good, and the screenshot concept is cool.
Did you try split testing a stronger call-to-action or the mini buttons from the screenshots worked out well?
great idea of showing them how to do it by includnig the facebook app authorisation screenshot and the arrow!! for a minute i thought you managed to embved the approval form in your lander but soon realised it was a screenshot.

Sick stuff Groomez. Props for your creativity & effort. That lander for the app is juicy. It's campaigns like these that own the typical direct dating campaigns 99% of affs try to run.
Thanks for the share!
Very nice!
Very nice case study man, keep droppin dem nuggetz!
Well deserved of the roi!!!
Nice piece of the puzzle man!
Sorry to bring this up, but the Pic used in the lander looks like a Hottie pinching her Nipples. How did FB approve that LP
?
Hehe, tricky stuff groomez. I just hope your Cloaking doesn't get detected by FB.
Hey groomez,
Nice case study man.
Am curious, .... your cloaker was a custom one you got made, or one you bought?
Awesome Groomez,
Been using an PHP clocker, which cloaks FB interns to approved LP.
How did you get around that your ad didn't call out the dating site you're advertising?
cool shit man. that app permission lander is fucking hot. I had my biggest days ever running apps direct linked w/ an angle very similar to this. I was very green at the time so I didn't try any sick ass landers like these, I would just make tons of ads for every hobby I could think of...Want a Rocker Chick? Want A Chick that believes in UFOs? Want a Date to the beach? Want a Skydiving partner?....allllll that shit. good times.
When using your own lander, do you need to link to a privacy policy and contact info, etc to be fb approved?
Just wanted to THANK groomez for this POST!
This is awesome! I applied what you had in this post, and my prior FB app on one angle, I use to just Direct link and break even or have a 20% ROI.. now I'm up to 50% ROI because of it! GREAT STUFF! Thanks again groomez and STM!
Thanks Polarbacon
Groomez I have to say a BIG THANK to you on this awesome post! Honestly, I am kinda lost in the sea after seeing my first 5 figures earnings last month direct linking, I didn't know what to do, shall I keep on pumping in more images? Shall I test new offers? In fact my offers are performing really well, with ROI of 60-100%!
Well, I really have to go back to making landers like yours. I have to admit I was lazy, really, but thank to you, I will no longer lazy! Thanks!
great post dude. too many affiliates forget to THINK when making their campaigns. we've become so accustomed to merely stealing, launching and hoping for the best.
good to see someone using their head.
Thanks for the case study groomez. Was the offer you ended up running in any way congruent with your "punk girls" sales pitch? Meaning, did the offer actually highlight or have pictures of punk, alternative, or girls that looked like your landers? Or was it just a mainstream dating offer?
The reason I ask is, I had a camp that I ran earlier in the year based around people with tatoos. The offer I was pushing actually had a section of the user profile where you could list if you had tats or not (that's where I got the idea), but on the surface it looked like a normal mainstream dating offer. I got some great CTRs but CV were on the low end no matter what I did. I figured this was due to people clicking ads with people all tatt'd up and they end up on a dating site for squares.
It's best if you can have a lander that tells them about tattoo, and when they click on it, they will arrive on a dating offer page where the angle that you Pre-sell them visible too.
I always make my angle based on the offer lander that the network has for me, because it makes sense that if you Pre-sell them something, they must be able to see it on the offer lander, because this decides whether the guy/girl will convert or not.
An example is that, if you market dating offer to people in new York, then the final lander must tell them "meet singles in New York!" instead of "meet singles in LA!".
Great post Groomez. In your post you say;
"Now, I did cloak to another PG offer like singlesnet or true for the facebook reviewers."
Was the singlesnet landingspage you cloacked to congruent with the ad about dating punk girls?
Because i've experienced that fb didnt allow me to run ads that were not congruent with the lp (when i chose a particular angle). What are your views on that?
Thanks for the post Groomez, I just wanted to ask how long ago you ran this campaign?
