The Casino affiliate programs
The difference a player gets between a single and multi tier casino affiliate program usually affects the payout or amount a player can gain and earn. For other people the amount of the income from the second tiers and onwards usually outweighs the income players get from the efforts they make.
There is absolutely no quick and hard rule as to what the house casinos and which sports books have what type or types of program. The difference lies in the fact that there are more software suppliers who consistently build the multi tier ability into the software while some don't. Most of the sports books don't provide the multi tier. They only give the multi tier after they outsource the program to a particular third party.
SINGLE TIER
The single tier is the most basic type of affiliate program. It involves an individual getting paid for all of the players one directs to the house casino or to the sports book and by extensive marketing ways and means the prospective players are then directed to the website but if the webmaster gets to follow the link, and then sign up for the affiliate program, then that webmaster could decide to market the site instead of the single tier maker but there would be no income received if the webmaster gets the opportunity to do this.
MULTI TIER
The Multi tier is actually based on the network of marketing traditionally made. The concept is the same where you can market the sports book or casino but in addition, one can do the marketing for the program affiliated. After the marketing effort you can obtain a certain percentage of income from the sub-affiliate. The sub-affiliate is also known as the downline. The formats of the links could be different sometimes. It always involves including the link of the webmaster in the site created. The percentage coming from the downline is lesser than the first tier and usually ranges from 1 - 5 percent. Once can think of it like a pyramid and most of the affiliate programs have either a couple of tiers, five tiers or ten.
The payments of the webmasters are not getting affected. It is because they act as sub-affiliates. In some cases the potential webmasters could not be even aware of the tiers. The webmasters still get the full payment and the tiers get a percentage from the income they make. The casino or the sports book shoulder the cost because the tiers act as marketing people for the sites so if someone is interested to become an affiliate, one can easily sign up under the affiliate link.
