Multiple IPs (load balancing) for same domain
-
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 4.4.4.4Every 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.

Why some domains and sub-domains have same DA, but some others don't?
Hi I noticed for some blog providers in my country, which provide a sub-domian address for their blogs. the sub-domain authority is exactly as the main domain. Whereas, for some other blog providers every subdomain has its different and lower authority. for example "ffff.blog.ir" and "blog.ir" both have domain authority of 60. It noteworthy to mention that the "ffff.blog.ir" does not even exist! This is while mihanblog.com and hfilm.mihanblog.com has diffrent page authority.

One domain - Multiple servers
Can I have the root domain pointing to one server and other URLs on the domain pointing to another server without redirecting, domain masking or HTML masking? Dealing with an old site that is a mess. I want to avoid migrating the old website to the new environment. I want to work on a page by page and section by section basis, and whatever gets ready to go live I will release on the new server while keeping all other pages untouched and live on the old server. What are your recommendations?

The benefits from having a dedicated IP
Is the true? Claim by SiteGround Having a dedicated IP for each website is considered by some experts as an advantage for search engine optimization. There is a common believe that sites with dedicated IP addresses do better in the search engine results than those on shared IPs. Such sites do not share the risk of being banned for sharing the same IP in case another website hosted on the same server gets banned by a search engine.

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!

Multiple 301 Redirects for the Same Page
Hi Mozzers, What happens if I have a trail of 301 redirects for the same page? For example,
Intermediate & Advanced SEO | | Travis-W
SiteA.com/10 --> SiteA.com/11 --> SiteA.com/13 --> SiteA.com/14 I know I lose a little bit of link juice by 301 redirecting.
The question is, would the link juice look like this for the example above? 100% --> 90% --> 81% -->72.9%
Or just 100% -----------------------------------------> 90% Does this link juice refer to juice from inbound links or links between internal pages on my site? Thanks!0 -
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?

One Business-Multiple Services

They want to maintain one website for branding purposes.

Multiple Domain names pointing at one website
Hello, A collegue has asked if we can buy multiple domain names which contain keywords and point them at our website. Is this good practise or will it be seen as spam? Will these domains actually get ranked? I'm sure I'm not the first person to raise this but can't seem to find any questions and answers about this. Thanks Mark
