Like Gooner said it depends on a lot of things. If your site (or sites) are more geared towards casinos, poker, or bingo you will probably get less CTR for a sportsbook banner as the traffic isn’t looking for a sportsbook. If you have more than one banner on a page the highest you can get is 50% of impressions or less. CTR depends on a lot of things. If you have less quality traffic it will probably be less as well. Page location of their adds would also affect this. Upper page adds get more clicks per impression than lower page adds.
You can do what you want, but I would try to figure out why it’s so low, see if it has anything to do with what you are doing before getting rid of what I would personally consider the best sportbook affiliate program available. They have very good sportsbook properties, twice as many deposit options as most sportsbooks (including citadel, moneybookers, and click2pay which most sportsbooks don’t cater to) , and pay their affiliates on a regular basis.
But do what you must, this is just one portal owners 2 cents.
