Recently I have been going for some very competitive keywords, so I have decided to look into getting different I.P addresses for each website I have, and I have took analytics off and not used webmaster tools. I have some questions for those that have done it already. 1. I have got class c I.p addresses, but you get extra I.P's would google still realise if you use i.e 73.673.78.01 and 73.673.78.02 I am guessing they would? 2. Would you have to have different nameservers for each websites? Are there any other tracers apart from whois info? such as name, address
Almost every address on the web is a class C address. So I don't know why you would think Google gives less weight to them. Class A & B addresses are almost unheard of. No one uses them because they don't need that many unique IPs exposed to the web. We have a server farm with 30+ web servers. From the web it looks as if they all share a single IP - the IP of our load balancer. And Google treats shared IPs the same as dedicated IPs from a ranking perspective. Having a dedicated IP can, however, save you from being accidentally penalized should a link farm exist on your shared IP address and Google penalize all the domains at that IP - a sort of guilty by association penalty (a quick reconsideration request will get you un-penalized, but you can avoid the hassle with a dedicated IP). Unless you have a huge farm of web sites that you are trying to interlink, having different IPs and different registrant information is not going to really help you. You can have a reasonable number of web sites (5 or10) and interlink them without any fear of penalty as long as the sites you interlink are relevant sites. If you're trying to maintain and interlink any more sites than that, it's quite obvious you're probably building a link farm. Then you should start worrying about separate IPs and registrant info.
Why would 10 sites be the max? Just curious.. Edit: Btw, under manual review its possible they could make a correlation.
So what if they correlate that you own 5 sites that interlink. As long as they are relevant to one another and the link on site A to site B provides some benefit to the users of site A like access to useful information about the topic of site A then the fact that it ALSO provides an SEO benefit to site B is irrelevant as is the fact that you own them both. Hell, you could probably interlink 5 unrelated sites and still pass a manual review. People often list and link to other sites they own. I said 5-10 sites because that is what I've heard from Cutts and other Googlers over an over. Can you "really" maintain and generate unique and useful content for more than that many sites? You might be able to get away with 20 or 30 sites... who knows... But if they review your sites manually, discover you own that many and are interlinking them, it's bound to raise WAY more eyebrows than if you're interlinking 5-10 sites about related topics. Here's a video where Cutts discusses it about 25 secs into the clip.
Thanks Canonical, I was hoping you would answer this thread, your one of the few guys on here that seems to know the score lol. Most of the "seo" guys around here seem to be interested in a quick, cheap, fast worthless gain etc. I would never build a link farm, I try and do everything whitehat although technically masking the ownership of websites is greyhat. Its just that I would like to build a load of blogs, which appear to be separate owners etc. And despite what Matt Cutts says, I do feel that linking to our own sites gives it less weight. I wasn't talking about being penalised or banned, just the way it looks to google. i.e Its not saying much if a blog owner writing about his own site on several sites, but having 10 seperate blog owners write about someone site, has alot more weight. Previously I havent worried about this, simply because i wasn't going for a seriously competitive single keyword. I feel that I should be doing everything 100% to the best of my skills, at the moment, I am making great tracks, and this project will prove my skills to anyone who asks for evidence. I am working 12 plus hours per day on Off page work for one site. The only problem is, I have unique I.P's now but don't I need to have a different nameserver for each one? Half of me is saying to give up on this idea, the other half is saying I should do it, as its more effort and seems like the right thing to do.
yes i guess they will recognize that those sites belongs to you if you are using the same class C, however concerning your other question about tracers, nameservers.. you are worried too much. and i can't really comment because i don't what are you doing with those websites exactly.
My plan is to use different IP addresses totally for each blog, and use the blogs to promote sites that I am working on, but I feel to get more weight with the backlinks, its best that the sites look totally unlinked. But my concern is that now I have got seperate I.P addresses, but will that be a waste of time with the same nameservers? Or should I just give up, and wack on analytics, adsense and links and have same i.p as its alot less work?
you atually brought up a very interesting point, we know for sure that google check the location and the ip of websites for various purposes, but i really can't comment about name servers because i don't know.
