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.

Does redirecting from a "bad" domain "infect" the new domain?
Hi all, So a complicated question that requires a little background. I bought unseenjapan.com to serve as a legitimate news site about a year ago. Social media and content growth has been good. Unfortunately, one thing I didn't realize when I bought this domain was that it used to be a porn site. I've managed to muck out some of the damage already - primarily, I got major vendors like Macafee and OpenDNS to remove the "porn" categorization, which has unblocked the site at most schools & locations w/ public wifi. The sticky bit, however, is Google. Google has the domain filtered under SafeSearch, which means we're losing - and will continue to lose - a ton of organic traffic. I'm trying to figure out how to deal with this, and appeal the decision. Unfortunately, Google's Reconsideration Request form currently doesn't work unless your site has an existing manual action against it (mine does not). I've also heard such requests, even if I did figure out how to make them, often just get ignored for months on end. Now, I have a back up plan. I've registered unseen-japan.com, and I could just move my domain over to the new domain if I can't get this issue resolved. It would allow me to be on a domain with a clean history while not having to change my brand. But if I do that, and I set up 301 redirects from the former domain, will it simply cause the new domain to be perceived as an "adult" domain by Google? I.e., will the former URL's bad reputation carry over to the new one? I haven't made a decision one way or the other yet, so any insights are appreciated.

Hold Off on SEO Changes After Domain Migration?
We migrated our domain on April 4th. Our domain authority has dropped from 22 to 8. Traffic is down from 90 visits a day to 10. Search console has indexed about 120 out of 600 pages. I have been told it may take several months to recovers some element of domain authority. My SEO consultant has planned on implementing the following changes immediately: 1. Change in URL structure
Intermediate & Advanced SEO | | Kingalan1
2. Build internal links (my site has very few).
3. Optimize URLs for specific keywords
4. Keyword optimization of URLs using Yoast.
5. Modify Schema Do we risk confusing Google further by making these changes until are domain authority and traffic has recovered? Is it safe to proceed with some "softer" changes such building internal links and keyword optimizing text whicl avoiding more disruptive changes such as re-writing URLs? Are we better off focusing on off site ranking factors such as link building and local SEO until domain authority recovers? How about only adding new content to the site such as blog posts and listings? To complicate matters the site is old and dated and we are working on a new UX design. So perhaps it would be better to launch the new UX at the exact same time as the onsite SEO optimization occurs. This could be less work and less disruptive. At the same time I would very much like to enjoy benefits of optimizing SEO now. Any thoughts????? Also, my domain migration has killed traffic. It is very concerning!! Is a 90% drop in traffic normal in the first ten days!? Thanks everyone!!!

Duplicate content across domains?
Does anyone have suggestions for managing duplicate product/solution website content across domains? (specifically parent/child company domains) Is it advisable to do this? Will it hurt either domain? Any best practices when going down this path?

How Can I Redirect an Old Domain to Our New Domain in .htaccess?
There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

Linking from & to in domains and sub-domains
What's the best optimised linking between sub-domains and domains? And every time we'll give website link at top with logo...do we need to link sub-domain also with all it's pages? If example.com is domain and example.com/blog is sub-domain or sub-folder... Do we need to link to example.com from /blog? Do we need to give /blog link in all pages of /blog? Is there any difference in connecting domains with sub-domains and sub-folders?

Reverting back to old domain name.
I've recently been asked by a client if I can foresee any issues with reverting back to their original domain name. With the original domain name they had a pretty decent DA for their sector which they have now lost. Although I do appreciate that over time this might come back, the CEO is very keen to switch back to the old domain. They do currently have 301 redirects from the old domain to the new and have implemented rel canonical. As yet they have not notified Google of the change of address using Webmaster Tools. Can anyone forsee any issues with returning back to the old domain name? They have only been using the new domain name for a couple of months which currently has a DA for 1.

Multiple Ecommerce sites, same products
We are a large catalog company with thousands of products across 2 different domains. Google clearly knows that the sites are connected. Both domains are fairly well known brands - thousands of branded searches for each site per month. Roughly half of our products overlap - they appear on both sites. We have a known duplicate content issue - both sites having exactly the same product descriptions, and we are working on it. We've seen that when a product has different content on the 2 sites, frequently, both pages get to page 2 of the SERPs, but that's as far as it goes, despite aggressive white hat link building tactics. 1. Is it possible to get the same product pages on page 1 of the SERPs for both sites? (I think I know the answer...) 2. Should we be canonicalizing (is that a word?) products across the sites? This would get tricky - both sites have roughly the same domain authority, but in different niches. Certain products and keywords naturally rank better on 1 site or the other depending on the niche.

Multiple city network
Im currently setting up a large network and my original thought was to target keywords via the city and then setting up a website with the domain name being that keyword. Now im thinking that in the long run thats going to be a massive pain in my ass. Im thinking what i should do is something along these lines... "www.companyname.com/cityorkeywordhere" any thoughts? Thanks for the help
