should I optimize my campaign for ad clicks or conversions ?

Hi guys,

I started to promote few cpa(email submit) campaigns from maxBounty with facebook ads and built for each one a nice landing page(cuz facebook blocks direct linking from maxBounty), set the pixel and created campaigns with objective of conversions on FB.

I also set the charging method to CPC and, the conversion to pageView(custom event), and optimization for link clicks.

The result was that I get a nice CTR (~10%) for these ads but the amount of conversions(on FB) I see is much…

should I optimize my campaign for ad clicks or conversions ?
