Well, most of the obstacles are quite “forseen”.
Comparing U.K. (where you can bet on any sport any 5 feet) with USA (where you have to go to only one point in the country) is a big mistake. Even so, I have had awful experience with B&M gambling websites from the U.K.
The only good website with vast offline presence is WillHill, but they offer 20 local bucks per qualified sign up. I’ll be damned if I advertise MGM for $20 per player – compared to the $300 pre-UIGEA CPA from the offshores – it would be ridiculous.
And I strongly disagree with this:
Only time will tell, but a large business not using every conceivable advertising venue is a stupid business.
You can visit YouBet, the most popular legal online horse betting website, and look for an affiliate program, but you will not find it. And even their “refer a friend” program has a pretty lenghty small print.
