Duplicate content on subdomains.
-
Hi Mozer's,
I have a site www.xyz.com and also geo targeted sub domains www.uk.xyz.com, www.india.xyz.com and so on. All the sub domains have the content which is same as the content on the main domain that is www.xyz.com.
So, I want to know how can i avoid content duplication.
Many Thanks!

It would probably be better (and more likely to get you responses) if you started a new question - this one is three years old. Generally, I think it depends on your scope. If you need some kind of separation (corporate, legal, technical), then separate domains or sub-domains may make sense. They're also easier to target, in some ways. However, you're right that authority may be diluted and you'll need more marketing effort against each one.
If resources are limited and you don't need each country to be a fully separate entity, then you'll probably have less headaches with sub-folders. I'm speaking in broad generalities, though - this is a big decision that depends a lot on the details.
-
Dear all,
I have bought 30 geo top level domains. This is for an ecommerce project that has not launcehd yet (and isn't indexed by Google).
I am now at a point where I can change/consolidate all domains as sub domains or sub folders or keep things as they are.
I just worry that link building would be scattered and not focused and that it might be better to concentrate the efforts on one domain.
What are your views on this?
Many thanks.
-
Yeah - I'm really afraid that stacking all those sub-domains is going to cause you long-term issues with your link-building, and that some of those sub-domains could fragment. If the country needs to be in a sub-domain, then I think the hybrid approach (with "/shop" as a sub-folder) may cause you less trouble.
I will warn, though, that any change like this carries some risk. You'll have to put proper 301-redirects in place.
I might try the href lang tags first, though, and see if it helps the current problem (it may take a few weeks). Changing too many aspects of the on-page SEO at once could cause you a lot of grief.

shop. pages are simply new pages which are added for products to be sold with ease. I think that i might move shop.uk.xyz.com pages to uk.xyz.com/shop/product as in a sub folder. Do you think this will help in passing on the link juice to those pages after the change and would be easy for me to include them in the sitemap as well??
-
If you have separate GWT profiles, then I think the XML sitemap may have to be under the sub-domain - Google has to be able to access it from a sub-domain URL. It doesn't have to be in the root of the sub-domain.
I'm not clear on what the "shop." pages are, but stacking sub-domains like that sounds like it's getting pretty messy. Why the separation?
-
I have already created separate profiles for the subdomains, but my only worry is where to place the sitemap on the server eg in the root directory of the root domain or in the root directory of the sub domain.
Coming to the (2) the pages which i want to include in the site map are my product pages. so want to know if shop.uk.xyz.com can be included in the sitemap which will be for uk.xyz.com and also if does that count as a internal page of uk.xyz.com
-
It is probably best to create separate profiles in Google Webmaster Tools, because then you can target the sub-domains to the countries in question. At that point, you could also set up separate sitemaps. It'll give you a cleaner view of how each sub-domain is indexed and ranking.
I'm not sure I understand (2) - why wouldn't you include those pages in the sitemap?
-
Thank you for your inputs. I has relly helped me understand the situation.
I will try to implement this and let you know how I have done on this. Also I had few more things on this:
1. do i require a separate sitemap and robots file for all the sub domains and where shall i place it on the server?
2. in the sub domain there are pages like shop.uk.xyz.com/product1. so can i include that in the sitemaps as those are the pages which i really want to rank for.
-
There's no perfect answer. Canonical tags would keep the sub-domains from ranking, in many cases. The cross-TLD stuff is weird, though - Google can, in some cases, ignore the canonical if they think that one sub-domain is more appropriate for the country/ccTLD the searcher is using.
Sub-domains can be tricky in and of themselves, unfortunately, because they sometimes fragment and don't pass link "juice" fully to the root domain. I generally still think sub-folders are better for cases like this, but obviously that would be a big change (and potentially risky).
You could try the rel="alternate" hreflang tags. They're similar to canonical (a bit weaker), but basically are designed to handle the same content in different languages and regions:
http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077
They're basically designed for exactly this problem. You can set the root domain to "en-US", the UK sub-domain to "en-UK", etc. I've heard generally good things, and they're low-risk, but you have to try it and see. They can be a little tricky to implement properly.

No, 301 and canonicals are completely different
A 301 will redirect a page and a canonical is setting the preferred version of the page. For example:
301 - you have an old version of the page that looks like this www.example.com/p?=153 and you want it to look like www.example.com/red-apples. You would use a 301 from the old page (www.example.com/p?=153) to the new page (www.example.com/red-apples)
Canonical - Lets go back to the red apples example. Lets say you have a ecommerce site and you have different ways to search for products. One way is to search by fruit and the other by color. So what you'll have is two versions of the end result. For example. You'll have www.example.com/fruit/red-apples and you might have www.example.com/red/red-apples. Since both of those pages show the same information you don't want the engines to think its duplicate content so you can add a rel=canonical link element to both pages to the preferred version of the two. (ie you might want to have the canonical be www.example.com/red-apples) That's all it does. It tells the engines your preferred version of the pages that may be the same.
Back to your original post, you really don't need to "noindex" but I thought you were having a duplicate content issue and that would solve the issue. (Generally, Google won't penalize you this sort of duplicate content)
Here is what I would do.
If you don't have Google Webmaster tools already set up then do so. Verify each version of your subdomain, (ie. india.xyz.com, uk.xyz.com, etc)(let me know if you need help) and then set your Geo Target for each them manually (You'll have to set this up manually because you have a gTLD and not a ccTLD)
How to set your Geo Target manually.
To to a particular version of your site in WMT (ie. india.xyz.com) and click on "configuration" then "settings". Under "settings" the first sections says "Geographical Target". "Check" the box and then use the drop down to select "india".
Repeat this for all of your subdomains for each specific country.
This will let Google know that you are trying to target users in a specific country.
If you have the money to invest in it, I would also try to have those subdomains hosted by a server in each particular country. (strong signal for Google)
Hope it helps.

Thanx Darin!
I have few doubts on this:
1. is rel canonical like a 301 redirect? As my concern is if my user goes to www.uk.xyz.com/productx , will he be redirected to to www.xyz.com/product
2. my sub domain pages are ranking in the country specific search engine. For ex, www.uk.xyz.com is ranking for keywords in google.co.uk. So if i noindex then i will loose my search engine presence in the country specific search engine.
PS the content on the pages is all same apart from the product currency.
-
I disagree. I said "noindex" not "nofollow". Link juice will be passed but not show up in the Serps. I do agree with you though that the strategy as a whole, if there is in-fact exact/duplicate content, seems to be a waste. Unless these pages are in another language, I don't see the point of this subdomain strategy.
-
Canonical will help to remove duplicate issues and also to consolidate your link values. I didn't see any issue with cross domain implementation.
If you add "noindex" to any of these pages, you won't get any link credit.
-
Short Answer: Set a canonical url on the pages to the root domain version and noindex the subdomain pages.
What this does is avoid the duplicate content problem. Generally, those subdomain pages won't rank anyway because the same information is on the "main" site. You can still build links to those subdomain pages and do a strong internal link structure to help the "main" site rankings.
The only negative to this is that the pages in your subdomain won't rank. That's not necessarily a bad thing but just know they won't. But, if the pages are truly duplicate content, they won't rank anyway.

Duplicate content across different domains in different countries?
Hi Guys, We have a 4 sites One in NZ, UK, Canada and Australia. All geo-targeting their respective countries in Google Search Console. The sites are identical. We recently added the same content to all 4 sites. Will this cause duplicate content issues or any issues even though they are in different countries and geo-targeting is set? Cheers.

Woocommerce SEO & Duplicate content?
Hi Moz fellows, I'm new to Woocommerce and couldn't find help on Google about certain SEO-related things. All my past projects were simple 5 pages websites + a blog, so I would just no-index categories, tags and archives to eliminate duplicate content errors. But with Woocommerce Product categories and tags, I've noticed that many e-Commerce websites with a high domain authority actually rank for certain keywords just by having their category/tags indexed. For example keyword 'hippie clothes' = etsy.com/category/hippie-clothes (fictional example) The problem is that if I have 100 products and 10 categories & tags on my site it creates THOUSANDS of duplicate content errors, but If I 'non index' categories and tags they will never rank well once my domain authority rises... Anyone has experience/comments about this? I use SEO by Yoast plugin. Your help is greatly appreciated! Thank you in advance. -Marc

Duplicate Content Dilemma for Category and Brand Pages
Hi, I have a online shop with categories such as: Trousers Shirts Shoes etc. But now I'm having a problem with further development.
Intermediate & Advanced SEO | | soralsokal
I'd like to introduce brand pages. In this case I would create new categories for Brand 1, Brand 2, etc... The text on categories and brand pages would be unique. But there will be an overlap in products. How do I deal with this from a duplicate content perspective? I'm appreciate your suggestions. Best, Robin0 -
Subcategories within "New Arrivals" section - duplicate content?
Hi there, My client runs an e-commerce store selling shoes that features a section called "New Arrivals" with subcategories, such as "shoes," "wedges," "boots," "sandals," etc. There are already main subcategories on the site that target these terms. These are specifically pages for "New Arrivals - Boots," etc. The shoes listed on each new arrivals subcategory page are also listed in the main subcategory page. Given that there is not really any search volume for "Brand + new arrivals in boots," but lots of search volume for "Brand + boots," what is the proper way to handle these new arrivals subcategory pages? Should each subcategory have a rel=canonical tag pointing to the main subcategory? Should they be de-indexed? Should I keep them all indexed but try to make the content as unique as possible? Thank you!

Is a different location in page title, h1 title, and meta description enough to avoid Duplicate Content concern?
I have a dynamic website which will have location-based internal pages that will have a <title>and <h1> title, and meta description tag that will include the subregion of a city. Each page also will have an 'info' section describing the generic product/service offered which will also include the name of the subregion. The 'specific product/service content will be dynamic but in some cases will be almost identical--ie subregion A may sometimes have the same specific content result as subregion B. Will the difference of just the location put in each of the above tags be enough for me to avoid a Duplicate Content concern?</p></title>

Product descriptions & Duplicate Content: between fears and reality
Hello everybody, I've been reading quite a lot recently about this topic and I would like to have your opinion about the following conclusion: ecommerce websites should have their own product descriptions if they can manage it (it will be beneficial for their SERPs rankings) but the ones who cannot won't be penalized by having the same product descriptions (or part of the same descriptions) IF it is only a "small" part of their content (user reviews, similar products, etc). What I mean is that among the signals that Google uses to guess which sites should be penalized or not, there is the ratio "quantity of duplicate content VS quantity of content in the page" : having 5-10 % of a page text corresponding to duplicate content might not be harmed while a page which has 50-75 % of a content page duplicated from an other site... what do you think? Can the "internal" duplicated content (for example 3 pages about the same product which is having 3 diferent colors -> 1 page per product color) be considered as "bad" as the "external" duplicated content (same product description on diferent sites) ? Thanks in advance for your opinions!

Google WMT Showing Duplicate Content, But There is None
In the HTML improvements section of Google Webmaster Tools, it is showing duplicate content and I have verified that the duplicate content they are listing does not exist. I actually have another duplicate content issue I am baffled by, but that it already being discussed on another thread. These are the pages they are saying have duplicate META descriptions, http://www.hanneganremodeling.com/bathroom-remodeling.html (META from bathroom remodeling page) <meta name="<a class="attribute-value">description</a>" content="<a class="attribute-value">Bathroom Remodeling Washington DC, Bathroom Renovation Washington DC, Bath Remodel, Northern Virginia,DC, VA, Washington, Fairfax, Arlington, Virginia</a>" /> http://www.hanneganremodeling.com/estimate-request.html (META From estimate page) <meta name="<a class="attribute-value">description</a>" content="<a class="attribute-value">Free estimates basement remodeling, bathroom remodeling, home additions, renovations estimates, Washington DC area</a>" /> WlO9TLh

I have a duplicate content problem
The website guy that made the website for my business Premier Martial Arts Austin disappeared and didn't set up that www. was to begin each URL, so I now have a duplicate content problem and don't want to be penalized for it. I tried to show in Webmaster tools the preferred setup but can't get it to OK that I'm the website owner. Any idea as what to do?
