I am thinking about a new product directed toward online glambers -- I am not marketing a gambling product but support service.
I have thought about that but the biggest one I found have 5000 members out of the estimated 5 million.
well generally the best way to promote something in gambling is through an affiliate program.. So if you can promise good comissions set it up! also check some forums here http://www.findinforums.com/search/online-gambling/1.html
Good advice, I have an affilitiate shareasale starting this weekend or Monday and since it is similar product I'll probably attach it to this deal. I just have to work out the pricing and commission. It relates to the upcoming ban on US credit cards and bank account.
Your product sounds interesting, but are you targeting the casino merchants or the gamblers? If you are targeting gamblers then you can use gaming forums and gaming affiliate networks. Try places like incentaclick, gambling911, majorwager, therx, etc. To reach bookies or merchants you may need to contact individual books. there are some known marketing companies who may have a database of all these offshore companies. PM me for details.
