IP ranges and matching WHOIS
-
I have a client who owns two large websites and they sit on the same IP Range: XXX.XX.11.124 and XXX.XX.11.126. Obviously the X's match. Furthermore the whois in the same.
Website A is really old and has millions of pages, but has some unintentional but spammy subdomains that are duplicate content.... we are talking thousands. At this point addressing those subdomains is not an option. Website A also links to millions of times to Website B, but those links are either nofollowed or in javascript.
Website A has a ton of duplicate content through job feeds.
Now Website B is about 4-5 years old and has a great link graph but has been hit hard by Panda in which we recovered only to dive again. My question is, Website B is very close to having near perfect onpage SEO, hierarchy, etc. Could website A be effecting it in anyway?
If we assume that Website A is impacting B, what is the safest solution.... change servers and IP addresses? Change host entirely? Do I need to worry about whois?
Thank you!

I think what your asking, at a deeper level, if the really crappy SEO on site A can effect site B, through some form of administrative relationship. Is this correct? If there is a lot of questionable linking between the sites, you can see some negative effects. (if there is no linking relationship between the sites, then the answer is almost always no)
I agree with Alan completely that changing servers, IP address and all that doesn't effect the issue that those links still point to your website. Changing the host or other administrative associations of any of these sites likely would have zero impact on any penalties.
First, you want to determine if site A really is the problem. Is it Panda? Is it Penguin? Make sure to match up the dates of your traffic fluctuation with historical algorythm changes. http://www.seomoz.org/google-algorithm-change
We seen a lot of site-wide cross linking, with over-optimized anchor text, as a key root of a lot of recent Penguin penalties.
All of these penalties have a lot of factors that could be the cause, so I'd make sure to look everywhere, including the links between the sites.

If Site A is a cash cow that does not need SEO, then I would block the entire site from search engines via robots.txt file. Even on separate hosts, all the links pointing to Site B are a big negative due to the sheer volume, given that there's likely a "bad rap" label associated with SEO on site A.
Duplicate content does not need a "same server" relationship to be a big problem either. All duplicate content is a problem regardless of location.
If a client I represent is doing things that I believe are impeding their success, I personally believe it's important to communicate my concern. However, if they choose to ignore that communication, that's their right to do so.

Honestly.. Site A is a Cash Cow that does not need SEO. I would love to clean it up, but there are external forces preventing that at the moment. These forces are not technical.
Site B is in the same industry as A, but with a different model and user. Both sites are pertient.
Let me simplify this question....
1.Can duplicate content effect more than just the root domain and spread across to other websites on the same IP range? and WHOIS?
2. Moreover does any SEO need to worry about what their clients are doing on sites that are out of their control (assuming no blackhat techniques)?
-
The question is this - why would you want to keep Site A given the current insurmountable challenge you describe?
Do you still hope there's some value in it being kept alive?
Do you still hope there's some SEO value or that the site will or does continue to bring some traffic you believe to be valuable?
Because (and this is just my opinion) if you are convinced you cannot or will not (for whatever reason) work to clean the mess up, you'd be better off completely killing off Site A.
If you don't even if you migrate site B to a different server, the links still exist. The footprint remains.

If You can't address them can you create a sitemap or robot that doesn't count them?

IP address geolocation
I would classify our site as large (www.covers.com), with our primary target being traffic within the US (about 70%) but I have a feeling we are limited by our IP being located within Canada. I have changed all the targeting to the US in WMT, but could undertake a project to virtually 'move' the site to a US IP, if there would be benefit. I have found articles coming down on both sides of the issue. Thoughts?

For a web agency, can the same WHOIS registrant name information between different domain names hurt SEO?
Hi, I own a web agency and we often register domain names for our clients. When we register those, I just realized that we always use the same registrant name and other whois (ex : Louis-Philippe Dea), for all domain names. Can this hurt the SEO of our clients? Hope that you'll understand when I'm trying to say in spite of my bad english :S Thanks 🙂

Client sites on same IP / same c class IP range
Our own site and client sites (that we design) are either hosted on the same IP or within same C Class range of IPs Will there be an issue with Google if we include a link on the client site home page footer (as agreed with client) that links to a specific project page on our website for that client e.g they are not linking to our home page?

Hacked Server IP Range Penality?
I use a justhost.com reseller account to host about 15-20 of my own websites. None of the sites are related, nor do I interlink or do anything blackhat with any of them. All of the sites have unique content. Some of it isn't great, but I didn't use a writing service on any of then, it was all written by myself. Recently I found a list of my sites (as well as about 200 others hosted by justhost) on a hacker website that listed the cpanel usernames. I alerted the host and the issue is being fixed. I am changing all of my usernames and passwords for all of the sites. Anyway, I recently took a look at some analytics and rankings and noticed that I lost a lot of my rankings on a handful of those sites recently. I know there was the big de-indexing of junk blogs recently, but I don't think that is the case. I can still find all of my sites in Google, they are just out of the first 50 results, when a majority of them were ranked from 5-20 in the SERPs. Here are three of the sites and their phrases: http://nintendoconsoles.com/ "nintendo consoles" - This domain I bought from someone so there could be some sort of sandbox period for it. http://webhostingfordrupal.com/ "web hosting for drupal" - This was a new register. http://seotirical.com "seotirical" - we don't show up, but all of the tweets and links to us do. - This was a new register. I realize these sites aren't perfect, and might not have been ready for the first page. The Nintendo site is about 3 months old, but the Drupal site has been around for 8+ months. I might try adding a fresh piece of content tonight to see if that helps, but I thought it was curious that it happened across the board with about 5-6 sites on my one reseller account. I don't even know if the top portion of this post has anything to do with the problems, but I thought I'd see if anyone has insight. Cheers,

Is IP-Hosting an effective and worthy SEO solution?
I have seen few websites selling same package of IP-Hosting, I consider that kind of smart SEO solution if it really be effective, But I have doubt. I have a few websites using a dedicated server for 6 years with only 1 valid IP and with that experience, I think rich content, title tags and anchor links are most important factors but I never tried such IP SEO, has any one tried IP hosting? Then comes second questions, If you have experienced and recommend IP Hosting, the reasonable application could be wordpress to manage all the sites in diffrent servers, and by using plugins such as autoblog or RSS importer we can update all the sites with minimum effort, But the problem is that neither of these 2 plugins are really working hassle free, They do not work at all or they stop wroking all the sudden, preferably I need a solution for Wordpress multisite Would you offer any alternative? I appreciate if you share your ideas... P.S.: My objective to apply IP hosting is not geo-targeting I use to launch .COMs normally without any particular geo-target.

SEO Benefit from Redirecting New Exact Match Domains?
Hi, All! This is a question asked in the old Q & A section, but the answer was a little ambiguous and it was about 3 years ago, so I decided to repost and let the knowledgeable SEO public answer... From David LaFerney: It’s clear that it’s much easier to get high rankings for a term if your domain is an exact match for the query. If you own several such domains that are very related such as – investmentrealestate.com, positivecashflow.com, and rentalproperty.com – would you be able to benefit from those by 301ing them to a single site, or would you have to maintain separate sites to help capture those targeted phrases? In a nutshell – SEO wise, is it worth owning multiple domains to exactly match valuable search phrases? Or do you lose the exact match benefit when you redirect?>> To clarify: redirecting an old domain with lots of history and links to a new exact match domain seems to contain SEO benefit. (You get links+exact match domain, approximately.) But the other way around? Redirecting a new exact match domain to an older domain with links? Does that do anything for the ranking of the old domain for the exact match keyword? Or absolutely nothing? (My impression has been that it's nothing, but the question came up for a client and I just wanted to make sure I wasn't missing something.) Thanks in advance!
