in terms of specifically setting up your ip addresses, did you use a version of seo hosting by host gator which only has about three servers or so but a plethora of different c classes, or did you register each domain with a different host company?
I have one two seo hosting accounts. One with 20 one with 10.
Rest are all on different hosts.
Same registar but all have privacy.
I'm not too worried, every single site is a quality site. There are some which are harder to have a lot of pages, but my smallest site is 3 pages, which is the only one with 3 pages, the rest are 4+ pages, some with 6,7,8 pages.
I have about 5 different templates I use. I change the colors, widths, make nice logos, add images to the articles, etc.
A couple of the sites are bringin in 400-600 visitors per day.
One 13 page site has about 6-7 pages in the top 10. Going to try and bring them all to #1.
I have a competitor who has done something similar, and his content is absolute crap. A lot of duplicate content, 3 page website, same template.
And he just has a "links" page, and puts about 100 links on it to his other sites. And they are all ranked pretty high. I don't know how that hasn't been banned yet. So I'm trying to catch up.
