Hello Stackers,
So, I've dabbled on fb a few times and I've made profits surprisingly. Usually 50-15% ROI, but the thing is that I really don't have any idea what I'm doing. Last year I did the following.
Read a guide on Attila's blog.
Signed up on AdCombo
Chose a vertical which is diet
Got a Spytool
Took a prelander on AdCombo
Got an Angle (AdCopy) and 2 Images From the spytool.
So the campaign setup was simple, Broad targetting of women 21 years-50
2 images, cloaked lander and 1 offer
I did this across different Geos. On days I was lucky to get replies from Attila (I was surprise to get replies on fb) I just duplicated the adsets.
Now, I'm seeing some trends on here like pixels, tracker and all that. I guess I've never setup a proper aff campaign 
I'm kinda lost 
There is no proper way honestly, depends on your accounts, the vertical you choose, geo, funnel etc etc. Why did you stop by the way with those ROI's? Seems you hit the sweep spot quite fast.
WH CPL or sweeps for example you can direct link without any extra tools and make some nice profits. For nutra you need to setup cloaking (trick FB), pixel (create LLA), good prelander (warm up consumers to convert) etc etc...
Find out where you think your skills/knowledge and interest will be exploited fully, then check out several networks for campaigns, spy a bit as you did before and test a lot!
I didn't cloak this time around, I used a Whitehat lander that is running for my ecom business here in Nigeria, I just translated it and removed some elements that weren't relevant to the offer, to be honest, I expected it to perform really well, cos it's doing quite well in Nigeria, spending about $150 and Making 700-2k daily revenue. but it flopped in the new geo (Tier 2 country)
Keitaro TDS, there's a tutorial on iamattila.com
