Te CAP Certification is all about money at this stage. The GPWA certification process involved me being asked a list of questions about the program, followed by them then signing up and trialing it. Most programs are listed on CAP because they need to be seen in the place to be. Personally I feel there are excellent quality webmasters on CAP and for this reason I am happy to signup and pay the annual advertising fee.
However I find it increasingly difficult to compete with over 60 other programs listed here and for this reason the ROI is quite low and has raised questions at management and board meetings when explaining the budget spend.
If CAP remove the certification and simply call themselves the #1 forum for gaming affiliates and venue to hang out this will make it easier to get the managers to sign off on an advertising spend.
I have been involved with CAP in some form or the other fix over 7 years so yes I do see an ROI for myself, but I also need to look out for the well-being of the programs.
If CAP does want to certify programs they need to have equal measures in place to certify and access each program and a starting point would be;
Software used
Complaints logged
Payout time
Time in industry
etc…
This is just my two cents and in no way reflects anyone elses opinion.
