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.

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!!

:Pointing hreflang to a different domain
Hi all, Let's say I have two websites: www.mywebsite.com and www.mywebsite.de - they share a lot of content but the main categories and URLs are almost always different. Am I right in saying I can't just set the hreflang tag on every page of www.mywebsite.com to read: rel='alternate' hreflang='de' href='http://mywebsite.de' /> That just won't do anything, right? Am I also right in saying that the only way to use hreflang properly across two domains is to have a customer hreflang tag on every page that has identical content translated into German? So for this page: www.mywebsite.com/page.html my hreflang tag for the german users would be: <link < span="">rel='alternate' hreflang='de' href='http://mywebsite.de/page.html' /></link <> Thanks for your time.

Multiple Landing Pages and Backlinks
I have a client that does website contract work for about 50 governmental county websites. The client has the ability to add a link back in the footer of each of these websites. I am wanting my client to get backlink juice for a different key phrase from each of the 50 agencies (basically just my keyphrase with the different county name in it). I also want a different landing page to rank for each term. The 50 different landing pages would be a bit like location pages for local search. Each one targets a different county. However, I do not have a lot of unique content for each page. Basically each page would follow the same format (but reference a different county name, and 10 different links from each county website). Is this a good SEO back link strategy? Do I need more unique content for each landing page in order to prevent duplicate content flags?

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!

Primary Domain or Redirect?
We are starting a new travel guide for a resort town. I have bought an expired domain with decent related links and PR (which seems to have survived the transfer (4 months ago). Beofre we launch the new site I am trying to decide if we should use this expired domain as the primary URL for the new site or just do a permanent redirect and buy a new domain that better matches the theme of the site. I am obviously concerned with starting from scatch with a new domain. I am confident we can build some good rellevant links in a short time but this space is very competetive. Any input would be greatly appreciated.

How do I list the subdomains of a domain?
Hi Mozers, I am trying to find what subdomains are currently active on a particular domain. Is there a way to get a list of this information? The only way I could think of doing it is to run a google search on; site:example.com -site:www.example.com The only issues with this approach is that a majority of the indexed pages exist on the non-www domain and I still have thousands of pages in the results (mainly from the non-www). Is there another way to do it in Google? OR is there a server admin online tool that will tell me this information? Cheers, Dan

Multiple stores & domains vs. One unified store (SEO pros / cons for E-Commerce)
Our company runs a number of individual online shops, specialised in particular products but all in the same genre of goods overall, with a specific and relevant domain name for each shop. At the moment the sites are separate, and not interlinked, i.e. Completely separate brands. An analogy could be something like clothing accessories (we are not in the clothing business): scarves.com, and silkties.com (our field is more niche than this) We are about to launch a related site, (e.g. handbags.com), in the same field again but without precisely overlapping products. We will produce this site on a newer, more flexible e-commerce platform, so now is a good time to consider whether we want to place all our sites together with one e-commerce system on the backend. Essentially, we need to know what the pros and cons would be of the various options facing us and how the SEO ranking is affected by the three possibilities. Option 1: continue with separate sites each with its own domains. Option 2: have multiple sites, each on their own domain, but on the same ecommerce system and visible linked together for the customer (with unified checkout) – on the top of each site could be a menu bar linking to each site: [Scarves.com] – [SilkTies.com] – [Handbags.com] The main question here is whether the multiple domains are mutually beneficial, particularly considerding how close to target keywords the individual domains are. If mutually benefitial, how does it compare to option 3: Option 3: Having recently acquired a domain name (e.g. accessories.com) which would cover the whole category together, we are presented with a third option: making one site selling all of these products in different categories. Our main concern here would be losing the ability to specifically target marketing, and losing the benefit of the domains with the key words in for what people are more likely to be searching for (e.g. 'silk tie') rather than 'accessories.' Is it worth taking the hit on losing these specific targeted domain names for the advantage of increased combined inbound links?
