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.

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.

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!

Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Redirect ruined domain to new domain without passing link juice
A new client has a domain which has been hammered by bad links, updates etc and it's basically on its arse because of previous SEO guys. They have various domains for their business (brand.com, brand.co.uk) and want to use a fresh domain and take it from there. Their current domain is brand.com (the ruined one). They're not bothered about the rankings for brand.com but they want to redirect brand.com to brand.co.uk so that previous clients can find them easily. Would a 302 redirect work for this? I don't want to set up a 301 redirect as I don't want any of the crappy links pointing across. Thanks!

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.

Recovery during domain migration
On average, how long does it takes to recover 80% of the rankings if two high authority domains are combined without chaging any content? I totally understand that each domain is different and search engines can treat them differently but if all the steps are followed to the T what are the chances?
