FB Ads related CPA Question

Hi, I just received an offer and I am thinking of getting leads from Facebook. The offer payout is around $2.00 per Conversion. The offer supports Social Media. And falls in the niche of Woman Beauty and Apparels.

So here are my questions -
1) Is Facebook the right place to promote the offer? cause I doubt I might incur a huge expense(loss)
2) In the target url should I simple paste the direct affiliate url? For example: hxxp://abc.example.com/aff_23?offer_id=xxx&aff_id=xxxx

HELP! This is my first online campaign in a CPA Network so a bit tensed..

1) Is Facebook the right place to promote the offer? cause I doubt I might incur a huge expense(loss)

Test and repeat the successful campaigns. Well Facebook is the next big thing that helps you go Viral. Sending in traffic within Facebook, say your Facebook fan page to build some fans related to your product won't cost you much. The CPC is quite less when traffic stays within Facebook.

2) In the target url should I simple paste the direct affiliate url? For example: hxxp://abc.example.com/aff_23?offer_id=xxx&aff_id=xxxx

Depends, if your affiliate allows direct linksing then well and good or else, send it to your landing page. Do remember, sometimes your custom landing page might convert much better than the direct affiliate site.
