Multiple Domains on 1 IP Address
-
We have multiple domains on the same C Block IP Address. Our main site is an eCommerce site, and we have separate domains for each of the following: our company blog (and other niche blogs), forum site, articles site and corporate site. They are all on the same server and hosted by the same web-hosting company.
They all have unique and different content. Speaking strictly from a technical standpoint, could this be hurting us? Can you please make a recommendation for the best practices when it comes to multiple domains like these and having separate or the same IP Addresses?
Thank you!

Sorry, I'm confused about the setup. Hosts routinely run multiple sites off of shared IPs, but each domain name resolves as itself. Users and search bots should never see that redirection at all and shouldn't be crawling the IPs. This isn't an SEO issue so much as a setup issue. Likewise, any rel=canonical tags on each site would be tied to that site's specific domain name.

Hello Peter,
We have three sites hosted on the same server with the same IP address. For SEO (to avoid duplicate content) reasons we need to redirect the IP address to the site - but there are three different sites. If we use the "rel canonical" code on the websites, these codes will be duplicates too, as the websites are mirrored versions of the sites with IP address, e.g. www.domainname.com/product-page and 23.34.45.99/product-page. What's the best ways to solve these duplicate content issues in this case? Many thanks!

I think that situation's a bit different - if you aren't interlinking and the sites are very different (your site vs. customer sites), there's no harm in shared hosting. If you share the IP and one site is hit with a severe penalty, there's a small chance of bleedover, but we don't even see that much these days. Now that we're running out of IPv4 addresses, shared IPs are a lot more common (by necessity).

I have something similar. I'm with Hostgator, I have a VPS level 5. It comes with 4 IP address's and I have about 15 sites, some mine, some customer sites spread out over the addresses. There is very little interlinking between the sites but I was concerned too. I have read that Add-on sites are bad for SEO, but as long as you arent feature building crappy sites and linking them to your main site, should be fine.

I think @cgman and @Nakul are both right, to a point. Technically, it's fine. Google doesn't penalize shared IPs (they're fairly common). If you're cross-linking your sites, though, it's very likely Google will devalue those links. That tactic has just been abused too much, and a shared IP is a dead giveaway.
Now, is it worth splitting all these out to gain a little more link-juice? In most cases, probably not. Google knows you own the sites, and may devalue them anyway. Chances are, they've already been devalued a bit. So, I don't think it's worth hours and hours and thousands of dollars to give them all their own homes, in most cases (it is highly situational, though).
The only other potential problem is if one site were penalized - there have been cases where that impacted sites on the same IP, especially cross-linked sites. It's not common, and you may not be at any risk, but it's not unheard of. As @Nakul said, it's a risk calculation.

I am presuming all those domains are linking to each other, correct ?
Are they regular or nofollow links ? It boils down how much authority you have on your main domain as well as the other domains. If I were you, I will keep the main e-commerce website on one server and everything else including niche blogs etc on a different server. It's not just SEO, but also security issues.
Essentially, to answer your question, it may not be hurting you to have the niche blogs, a forum with user generated content, the articles site and the corporate site on the same IP/server, but it would help you a lot more if they were on a different server, possibly different Class C IPs. So, you will gain from these links being on a different server. Keep in mind, these links are important for you and its good to increase their value by hosting them separately, because these sites are links that your competition can never get linked from. I would also consider doing a nofollow on them, and that's just my thoughts. I prefer lower risk. Again, it depends on what your e-commerce website's link profile is.

There is nothing wrong with having multiple sites / blogs on the same C block IP address. However, if you're trying to use your blogs to link to your products to boost SEO scores then you might want to consider other link building techniques in addition. Building backlinks from sites on same IP is okay, but you'll have greater benefits getting links from sites hosted on other servers.

Lost ranking after domain switch
I recently migrated from https://whitefusemedia.com to https://whitefuse.com. The website URL structure and content remained the same and I followed all the best practice guidance regarding checks on the new domain and appropriate 301 redirects. I have seen traffic drop by about 50% and the traffic that is still coming through is mainly coming through links still listed by Google under the old domain (https://whitefusemedia.com). Is this normal? Should I expect to see this bounce back, or is there anything I can do now to regain the rankings?

Spammers created bad links to old hacked domain, now redirected to our new domain. Advice?
My client had an old site hacked (let's call it "myolddomain.com") and the hackers created many links in other hacked sites with links such as http://myolddomain.com/styless.asp?jordan-12-taxi-kids-cheap-T8927.html The old myolddomain.com site was redirected to a different new site since then, but we still see over a thousand spam links showing up in the new site's Search Console 404 crawl errors report. Also, using the links: operator in google search, we see many results of spam links. Should we be worried about these bad links pointing to our old site and redirecting to 404s on the new site? What is the best recommendation to clean them up? Ignore? 410s? Other? I'm seeing conflicting advice out there. The old site is hosted by the client's previous web developer who doesn't want to clean anything up on their end without an ongoing hosting contract. So beyond turning redirects on or off, the client doesn't want to pay for any additional hosting. So we don't have much control over anything related to "myolddomain.com". 😞 Thanks in advance for any assistance!

Blocking certain countries via IP address location
We are a US based company that ships only to US and Canada. We've had two issues arise recently from foreign countries (Russia namely) that caused us to block access to our site from anyone attempting to interact with our store from outside of the US and Canada. 1. The first issue we encountered were fraudulent orders originating from Russia (using stolen card data) and then shipping to a US based International shipping aggregator. 2. The second issue was a consistent flow of Russian based "new customer" entries. My question to the MOZ community is this: are their any unintended consequences, from an SEO perspective, to blocking the viewing of our store from certain countries.

Rel canonical between mirrored domains
Hi all & happy new near! I'm new to SEO and could do with a spot of advice: I have a site that has several domains that mirror it (not good, I know...) So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content. I was planning to use rel="canonical" to avoid the duplication but I have a concern: Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp. I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
Technical SEO | | AlexSG
-The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
-The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locations Any opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa? I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot! Best regards from Singapore!0 -
Mobile Domain Setup
Hi, If I want to serve a subset of pages on my mobile set from my desktop site or the content is significantly different, i.e. it is not one to one or pages are a summarised version of the desktop, should I use m.site.com or is it still better to use site.com? Many thanks any help appreciated.

How do I check if my IP is blocked?
We changed servers and where our sites once ranked very highly (page 1 for all sites), they now are nowhere to be seen. Someone suggested that our IP might be blocked. Someone else suggested SEOMoz was the place to go to get it checked. Any help would be GREATLY appreciated. With thanks. Bryan

Why google index my IP URL
hi guys, a question please. if site:112.65.247.14 , you can see google index our website IP address, this could duplicate with our darwinmarketing.com content pages. i am not quite sure why google index my IP pages while index domain pages, i understand this could because of backlink, internal link and etc, but i don't see obvious issues there, also i have submit request to google team to remove ip address index, but seems no luck. Please do you have any other suggestion on this? i was trying to do change of address setting in Google Webmaster Tools, but didn't allow as it said "Restricted to root level domains only", any ideas? Thank you! boson

The effect of same IP addresses on SERPs
Hi All, Just wondering if anyone could shed some light on the following. If I was ranking number 1 for a term, what would the effects be of creating another site, hosted on the same server / IP, same whois info, same URL but a different TLD, and trying to get this to rank for the term also. Does G restrict search results to one IP per page or is this perfectly possible? (The term is fairly uncompetitive) Thanks, Ben
