I think if I can crack the code to sweeps on Facebook the possibilities are endless!
So I found a sweeps offer that pays 2.00.
Here is my prelander with a quiz
Here is the pop up after they submit the quiz 
So far here are my stats
Spent: $7.95
Reach: 2138
Link Clicks: 144
Clicks to offer: 26
Converions: 1
Where should I optimize to increase conversions?
Split test other landers thats the first thing you can do for sure
Do you cloak to run this?
18% ctr on the pre-lander isnt that good. Should aim for 50% or more preferably!
26 clicks and 1 conversion is too little data to conclude the offer is bad. 30 clicks and 3 conversions makes it look much better for example. Try to reach 100 clicks at least on offer page to have a decent view...
I would also interested if you can ran Sweeps uncloaked?
