What kinds of websites earn you the bigest revenues ?

Yes it’s perfectly fine to register gambling domain names at Godaddy.

You can go down either route when it comes to question 1. Some people advise starting out focusing a mini site on just one online casino / poker room and others like to build a bigger more general type site which has space for content.

If your skills lie strongly in link building I’d go for the mini site first but If you’re more of a writer and long tail guy then make sue you use these skills.

build 2 sites, one for casino and one for poker, make sure you do seo on both and get high quality one way links pointing to both sites, godaddy is fine, make sure you do a LOT of offpage optimization if you want to get anywhere with those terms…a lot of competition
