Subdomain canonicalisation
-
Hi Moz fans,
I had a telephone conversation with an SEO company last week and they mentioned that the following "versions" of my domain were causing a canonicalisation issue;
I've already fixed the /index.html issue but do the above 3 also need to be fixed? Is the best solution to use a 301 redirect?
As a side note, the SEOmoz web app doesn't identify these as being duplicate content...
Regards, Ash

Hey Ash,
If you use a canonical in the index.html, then when you load example.com or example.com/ or etc. etc. versions you basically load the index.html (in which there is configured the canonical link).
My developer usually makes a 301 redirect from non-www. to www. and we implement to canonical link into index.html and that is it
I hope it helped,
Istvan

Does a root domain get SEO power from its subdomains?
Hi there! I'd appreciate your help with the following case: a) Current 10-year-old website (community) on root domain "example.com" (250,000 incoming quality-backlinks) will move to the new subdomain "newsub.example.com" (301 redirects to the new subdomain for all current subfolders) b) A new website (shop) will launch on the root domain "example.com" Question: Will the new website on "example.com" get SEO power from the old website on "newsub.example.com"? SEO power = linkjuice/authority/trust/history/etc. from the 250,000 backlinks. What I'm trying to achieve: Maintain the built-up SEO power for the root domain "example.com" Thanks for sharing your thoughts on this! P.S. Plenty has been written about subdomains inheriting from their root domains (so please don't share input on the subdomain vs. subfolder debate). But I can't find satisfactory info about the other way around (root domains inheriting from their subdomains), e.g. if wikia.com gets SEO power from its subdomains superman.wikia.com, starwars.wikia.com, etc.)

Blog subdomain not redirecting
Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

Duplicate Content: Is a product feed/page rolled out across subdomains deemed duplicate content?
A company has a TLD (top-level-domain) which every single product: company.com/product/name.html The company also has subdomains (tailored to a range of products) which lists a choosen selection of the products from the TLD - sort of like a feed: subdomain.company.com/product/name.html The content on the TLD & subdomain product page are exactly the same and cannot be changed - CSS and HTML is slightly differant but the content (text and images) is exactly the same! My concern (and rightly so) is that Google will deem this to be duplicate content, therfore I'm going to have to add a rel cannonical tag into the header of all subdomain pages, pointing to the original product page on the TLD. Does this sound like the correct thing to do? Or is there a better solution? Moving on, not only are products fed onto subdomain, there are a handfull of other domains which list the products - again, the content (text and images) is exactly the same: other.com/product/name.html Would I be best placed to add a rel cannonical tag into the header of the product pages on other domains, pointing to the original product page on the actual TLD? Does rel cannonical work across domains? Would the product pages with a rel cannonical tag in the header still rank? Let me know if there is a better solution all-round!

Subdomains vs directories on existing website with good search traffic
Hello everyone, I operate a website called Icy Veins (www.icy-veins.com), which gives gaming advice for World of Warcraft and Hearthstone, two titles from Blizzard Entertainment. Up until recently, we had articles for both games on the main subdomain (www.icy-veins.com), without a directory structure. The articles for World of Warcraft ended in -wow and those for Hearthstone ended in -hearthstone and that was it. We are planning to cover more games from Blizzard entertainment soon, so we hired a SEO consultant to figure out whether we should use directories (www.icy-veins.com/wow/, www.icy-veins.com/hearthstone/, etc.) or subdomains (www.icy-veins.com, wow.icy-veins.com, hearthstone.icy-veins.com). For a number of reason, the consultant was adamant that subdomains was the way to go. So, I implemented subdomains and I have 301-redirects from all the old URLs to the new ones, and after 2 weeks, the amount of search traffic we get has been slowly decreasing, as the new URLs were getting index. Now, we are getting about 20%-25% less search traffic. For example, the week before the subdomains went live we received 900,000 visits from search engines (11-17 May). This week, we only received 700,000 visits. All our new URLs are indexed, but they rank slightly lower than the old URLs used to, so I was wondering if this was something that was to be expected and that will improve in time or if I should just go for subdomains. Thank you in advance.

Subdomains
HI there We have the following situation: www.client.com/home at /home we will have a iframe calling a subdomain data.client.com . We need to use this structure because the server structure our client have. Is there any way i can index just www.client.com/home instead the subdomain, but include the data from the iframe to be indexed ? saying that because if google shows up the subdomain page on the search results, it will not bring anything as we need /home to the iframe/subdomain to work. So, google should just index /home and the data from the subdomain, but not the subdomain itself. Does it make sense? If not, any recommendation how it should be setup? Appreciate any help.

Domain Links or SubDomain Links, which is better?
Hi, I only now found out that www.domain.com and www.domain.com/ are different. Most of my external links are directed to www.domain.com/

Which I understand is considered the subdomain and not the domain. Should I redirect? (and if so how?)
Should I post new links only to my domain?0 -
Subdomain v. subdirectory v. other domain for blogs
I have a good amount of content on our main domain ( http://m00.biz/w4Ljfr ) let's say for discussion it's doctors.com and as you can see, much of it is in subdirectories. Traditionally this was the approach. Now I have some other content on subdomains but it's primarily directories and databases. Now I see that Google is giving subdomains their own SER as if they are a separate site and competitors are locking in the top few results merely by having their content on subdomains. Now I have an opportunity of doing two things: 1. Current content: moving all the content of the past few years on their own subdomain (forum, blog), and I'll be moving forum software anyways. Not sure about our own guide, which has been up there for a while. 2. New content: putting up some new blogs/magazines such as "Doctor's Handbook." Let's say that is a common phrase. I can choose between the following: (a) www.doctors.com/handbook/ (b) handbook.doctors.com/ (c) www.doctorshandbook.com I've got a bit of a quandary here, not sure of the best course of action and am curious to hear from many of you who have handled situations like this before.
