      Hello,

      I'm considering moving our main website to a multiple servers, perhaps in multiple different datacenters and use a DNS round robin load balancing by assigning it 4 different IP addresses (probably from 4 different C classes).

      example:
      ourdomain.com A  1.1.1.1
      ourdomain.com A  2.2.2.2
      ourdomain.com A  3.3.3.3
      ourdomain.com A  4.4.4.4

      Every time you ping the domain you will get a response from another IP of the group.

      Therefore search engines will see a different IP each time they scan the site.

      We have used the main IP for our website for past 6 years without changing it. We have a quite good SEO in our niche which I don't want to loose of course.

      My question is, will adding more IPs to the domain affect any how on the ranking ? What is the suggested way to do it anyway? What is recommended to do before and after?

      Thanks for you attention and help in advance.

      Dmitry S.

        No way. Google may care about DNS repoints, but that's something else entirely.

        Google barely cares about shared IPs and 'bad neighborhoods' at this point - so I doubt the IP address matters. Plus, we have several clients using hardware load balancers that do exactly what you describe, and it doesn't hurt them.

          As far as I know (according to what my colleagues opinions) rank is also linked somehow to the IP address, and from what i've been told, it takes some time until Google learns a new IP address and return the rank to the domain/page.

            SEO is linked to your domain name, not the IP address.  Think of these two scenarios.

            1:  You move your website hosting company.  Your website obviously will get a new IP.  Google has stated that this does not affect your SEO.

            2:  You have your domain hosted on shared hosting.  There would then be thousands of sites with the same IP.  You clearly don't all share the same SEO values.

              We work with load balancing a lot using multiple IPs - there are no issues SEO wise however you must be certain that those IPs, in the past, didn't got associated with spam or are on any black lists from previous users as in this case you can get a red flag for bad neighborhood.

              In my personal experience this is the only down side - if this is ok - there is no reason for concern - only good things can happen.

              Hope it helps.

                Cleaning up a Spammy Domain VS Starting Fresh with a New Domain

                Hi- Can you give me your opinion please... if you look at murrayroofing.com and see the high SPAM score- and the fact that our domain has been put on some spammy sites over the years- Is it better and faster to place higher in google SERP if we create a fresh new domain? My theory is we will spin our wheels trying to get unlisted from alot of those spammy linking sites. And that it would be faster to see results using a fresh new domain rather than trying to clean up the current spammy doamin. Thanks in advance - You guys have been awesome!!

                Does having multiple Domain aliases hurt SEO rank ?

                Our company having multiple domain aliases (DIfferent TLD) like example.com, .net, .org, .club, .win to one site (Same Content). We do this because our country ISP is blocking a few of the domain aliases. Question: Does this hurt the SEO rank? What approach is the best for us to gain SEO Rank?

                How can I prevent duplicate pages being indexed because of load balancer (hosting)?

                The site that I am optimising has a problem with duplicate pages being indexed as a result of the load balancer (which is required and set up by the hosting company). The load balancer passes the site through to 2 different URLs: www.domain.com www2.domain.com Some how, Google have indexed 2 of the same URLs (which I was obviously hoping they wouldn't) - the first on www and the second on www2. The hosting is a mirror image of each other (www and www2), meaning I can't upload a robots.txt to the root of www2.domain.com disallowing all. Also, I can't add a canonical script into the website header of www2.domain.com pointing the individual URLs through to www.domain.com etc. Any suggestions as to how I can resolve this issue would be greatly appreciated!

                Why would our server return a 301 status code when Googlebot visits from one IP, but a 200 from a different IP?

                I have begun a daily process of analyzing a site's Web server log files and have noticed something that seems odd. There are several IP addresses from which Googlebot crawls that our server returns a 301 status code for every request, consistently, day after day. In nearly all cases, these are not URLs that should 301. When Googlebot visits from other IP addresses, the exact same pages are returned with a 200 status code. Is this normal? If so, why? If not, why not? I am concerned that our server returning an inaccurate status code is interfering with the site being effectively crawled as quickly and as often as it might be if this weren't happening. Thanks guys!

                Should I redirect my Google Update Effected Domain to brand new Domain?

                Hey Moz experts, I had a domain which was really doing better but after the Humming Bird update my traffic was decreased up to 90%. There are plenty of posts on my existing blog, Now what should I do? I mean should I redirect it to a brand new domain or Copy all the posts to a brand new domain and delete my existing domain? Note that the Old domain has PR1, DA 19 and PA 30.

                Is it safe to 301 redirect old domain to new domain after a manual unnatural links penalty?

                I have recently taken on a client that has been manually penalised for spammy link building by two previous SEOs. Having just read this excellent discussion, http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience I am weighing up the odds of whether it's better to cut losses and recommend moving domains. I had thought under these circumstances it was important not to 301 the old domain to the new domain but the author (Lewis Sellers) comments on 3/4/13 that he is aware of forwards having been implemented without transferring the penalty to the new domain. http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience#jtc216689 Is it safe to 301? What's the latest thinking?

                Multiple Authors Google + Authorship

                Hello, I took a look through past questions but can't seem to find a definitive answer on setting up Google + Authorship credit (for multiple authors) using a Wordpress blog. Has anyone had experience setting this up? Or could you recommend solid reading/research? I took a look at a couple of Wordpress plug in's but just found them very confusing (so did our IT contact who will ultimately be setting up code for this.) Any direction or advice is appreciated.

                Deferred javascript loading

                Hi! This follows on from my last question. I'm trying to improve the page load speed for http://www.gear-zone.co.uk/. Currently, Google rate the page speed of the GZ site at 91/100 – with the javascript being the only place where points are being deducated. The only problem is, the JS relates to the trustpilot widget, and social links at the bottom of the page – neither of which work when they are deferred. Normally, we would add the defer attribute to the script tags, but by doing so it waits until the page is fully loaded before executing the scripts. As both the js I mentioned (reviews and buttons) use the document.Write command, adding this would write the code off the page and out of placement from where they should be. Anyone have any ideas?
