Can you be more explicit? What do you mean by a problem indexing? You have built links to them and they cannot be found in search engines?
Who setup your site? It's a freakin' nightmare. If I request www.onlineroulette.uk.com I get 302 redirected to http://81.21.76.62/onlineroulette.uk.com/index.html. Why on earth would you redirect a domain to a specific IP address with the domain as a subfolder like this? Terrible idea. And likewise... If I request www.freebet.uk.net then I get redirected to http://81.21.76.62/freebet.uk.net/index.html. What a freaking mess. I would contact your hosting company and ask them WTF they are doing and demand that they fix it ASAP. You should not be seeing IP addresses in front of your domain name. Basically your domain appears as if it is just a file or folder on one big web at that IP. And they should not be 302 redirecting requests for your domain anywhere.
Yes you will need to get this fixed before anything else. In the niche you have selected you will need all the help you can get.
