I have been pondering over this a bit and couldn't get a solution to my problem so I came over here and felt like asking you for help. I have a 25 C Class IPs package with http://www.SEOhost.com I host 25 different .com domains on each of these IPs that link to my main money site and have interlinked them using a neat strategy. I have Web 2.0 links pointing to each of these websites and I'm making over $1,500 a month just from these sites through affiliate links etc. I'm planning to run an xRumer blast to all these 25 websites, do you think it is a good idea? I currently have an xrumer blast run on each of the ~150 web 2.0 properties that link to these 25 sites but do you think it would be a problem if I run a blast to these 25 sites too? I'm making a substantial amount of money from these sites and hence I'm paranoid about taking this step. I asked the support techs at SEOhost.com but they adviced me against it. What do you think I should do? Another option for me is : Running a trial Another 25 IPs would cost me $50/mo. more, and 25 domains would cost about 180$. I could run blasts to these new domains and see how it works out and then try in on the primary money makers but the test wouldn't be accurate since a lot of factors differ. Like the domains would be new, not aged, etc. Oh, btw, just putting in a good word for SEOhost.com, they're AWESOME! Great support and great service, highly recommended. Felt like spreading the word around for them because they go out of their way to help. Anyways, back to my problem --> WHAT DO YOU SUGGEST I DO? PLEASE HELP ME BEFORE I PULL MY HAIR OUT!
