Hi guys, so i'm looking to start testing a sweepstake offer on facebook, i'm an affiliate on maxbounty and i've found a bunch with some pretty great EPC's. Thing is, i do not know if i should pick the ones that pay $22 and requires a payment, or the email submit ones that pay $1 - $2. Both have great EPC's but i would imagine alot of the leads gets scrubbed on the email submit ones?
does anyone have experience running these kinds of offers on facebook? got any tips?
If you have a smaller budget start testing those email submit offers.
Keep in mind that the EPC you see in the network is just an overall number that indicates the average epc of all traffic sources. It's a good indicator to pick offers for testing but don't expect the same results.
Don't worry about scrubbing because no matter what offer you run you're most likely being scrubbed, it's just part of the game. All networks deny this fact but you can never see their backend so it just stays as a guess game.
Good luck! 
do you have to cloak to run SOI sweeps on fb?
i suggest starting with the email submits and move to the higher payout offer after you manage to get positive ROI.
regarding scrubs they can happen both on the email and on the deposit as users can always do charge backs.
regarding scrubbing is part of the game well it is, saying that its 100% i can argue about it, there are affiliates who are getting more scrubs then others and this is depends on their traffic sources/quality and the network they work with.
Not all network are doing automatically scrubs and that is why you should always split test even the same offer with different network.
this will allow you to know if some network are scrubbing more than the other and it will allow you to not put your all eggs in one basket so if one network lose the offer you can still promote it with the other network that still have it live.
By the way, at which point do you stop testing images for ctr? i'm having no trouble at all reaching 0.3 - 0.4 ctr on all of my ads, but from what i've heard thats really good, and i do not know if any more testing would be a bad way to spend my time?
Thank you for all the great answers, i'm going to run some email submits outside of the US. Will let you know what happens.
