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.

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.

When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?
We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains? Also if you could provide any sources of information that specify this, I can't see to find anything!

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

Why is my domain authority still 1?
I changed the domain of my website from www.vanillacrush.co.uk to www.carissamay.co.uk at the end of December and yet my DA for carissamay is still 1. As advised, I set up a 301 redirect from VC to CM which seems to be working fine. However when I check on redirect detective it tells me I also have a 302 set up. Could this be confusing things? http://www.vanillacrush.co.uk

Two blogs on a single domain?
Hi guys, Does anyone have any experience of having (trying to rank) two separate blogs existing on one domain, for instance: www.companysite.com/service1/blogwww.companysite.com/service2/blogThese 2 pages (service 1 and service 2) offer completely different services (rank for different keywords).(for example, a company that provides 2 separate services: SEO service and IT service)Do you think it is a good/bad/confusing search engine practice trying to have separate blogs for each service or do you think there should be only one blog that contains content for both services?Bearing in mind that there is an already existing subdomain for a non-profit part of business that ranks for different keywords: non-profit.companysite.comand it will potentially have another blog so the URL would look like: non-profit.companysite.com/blogAny ideas would be appreciated!Thanks

Domain Redirect and SSL Cert
Hi, When redirecting an entire site to another domain, do you have to maintain the SSL certificate? The SSL expires 3 days before the planned redirect. Thanks in advance.

Will multiple domains from the same company rank for the same keyword search?
I'm trying to convince people that we need good marketing reasons for starting multiple domains, as it will be more difficult to rank multiple sites. Does anyone know if Google actively discourages multiple domains from the same company appearing in the search results for the same keyword? We are creating a separate content website which is related to an existing company website. Would you agree that is best to have these sites on one domain with the content site on a sub-domain perhaps? I'm worried about duplication of effort and cross-keyword targeting in particular. These sites would not have duplicate content.

Merging Domains... Sub-domains, Directories or Seperate Sites?
Hello! I am hoping you can help me decide the best path to take here... A little background: I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues. These three domains are PR4, PR4, PR5 and contain hundreds of unique articles. Here's the question... They want to move these three sites **to their main company site (PR4) and create sub domains for each one. ** I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective. Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this? Thanks in advance for the help! SD P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

Hosting images on multiple domains
I'm taking the following from http://developer.yahoo.com/performance/rules.html "Splitting components allows you to maximize parallel downloads. Make sure you're using not more than 2-4 domains because of the DNS lookup penalty. For example, you can host your HTML and dynamic content on www.example.org and split static components between static1.example.org and static2.example.org" What I want to do is load page images (it's an eCommerce site) from multiple sub domains to reduce load times. I'm assuming that this is perfectly OK to do - I cannot think of any reason that this wouldn't be a good tactic to go with. Does anyone know of (or can think of) a reason why taking this approach could be in any way detrimental. Cheers mozzers.
