Im talking here about casino NDBs only, and no free sports bets.
Also no dep exclusives are big part of our branding ( not the only one ofc ), and our focus is on converting such players in cooperation with the operators.
obviously the volume of our traffic is something that helps tremendously as in that quantity we find good quality.
We also have huge forum with over 50,000 members which obviously helps in presenting such offers to our membership ( among other things ).
Also there is a thing we call conversion lag where some of the referred players deposit the following month for the first time. But that still adds to your general conversion rate on a free chip.
