Question about CPA offer EPC and CR

Hey, I am new to CPA, so I have a noobish question, what is the difference between these two offers? First one: http://postimg.org/image/9rfy7m2yv/Second one: http://postimg.org/image/lhtvozvrb/ When EPC is $0 and CR is at 0%, the offer is worthless? Can't money be made from that offer? What exactly is EPC and CR? Thanks in advance.

any one can help for this ? i have same question

Not necessarily, it just means nobody has promoted the offer and (or) had conversions yet.

EPC stands for - Earnings Per Click - which is a statistical number, showing much you make per each click on average. Example: if you have 15 clicks and earned $1.40 then your EPC will be: 1.40/15 = 9,33%
CR stands for - Conversion Rate - which is a statistical number, showing how the offer is converting. Example: if you have 15 clicks and 1 lead/sale then your CR will be: 1/15 = 6,67%

Hope this helps a bit
