Are sub domains considered completely different than the root domain?
-
We have a project that is going to generate duplicate content. If we move the new content to a sub-domain (E.g. product.domain.com) will it still be considered duplicate content to the root domain? Or is it like having two completely different domains?
Thanks!

Cyrus is right!

Unfortunately, it doesn't work this way. See my comment above.

In the case of duplicate content, you always have to tell the search engines which is the canonical (the authoritative version). It doesn't matter if they are on the same website, different sub-domains, or completely different websites.
If you leave it up to Google to choose, often the ranking power of both pages is diminished, and if you have too much duplicate content, your entire site can suffer.
Either choose the page you want to rank, and send the appropriate signals to search engines, or create different content for different pages.

Yes they do
Just so you know , when you add a rel canonical the duplicate pages will drop from the SERPs eventually ( assuming google accepts the rel canonical , they don't always do it )

Thanks Saijo,
That is exactly what we are going to do. We are going to use the canonical tag on the new duplicate pages referencing the existing pages that have achieved rank. Quick question on that, do you know if "juice" is transferred through a canonical tag? The new pages will be getting some pretty great links but not enough to rank highly. Will this juice be passed to the existing pages through the canonical tag?

There is not enough information here to give you the right answer, but here is my 2 cents on the topic
Say you need these duplicate pages to exist for some reason and do NOT want them to be indexed . You can noindex them and have them in the subdomain. So they do not appear in the SERPs and are not duplicate content because Google ignores them. ( Think of it this way : you are telling google , these are duplicate pages and its not meant for the search results )
Say you need these duplicate pages to be indexed , then you use rel canonical on the duplicate pages all tell Google the main page you want to be indexed. ( Think of it this way : you are telling google , these are duplicate pages and you want importance to go to the main one ) FYI : over time this means the other pages will fade away in SERPs
What you don't want to do : put duplicate pages up on sub domain and making no effort to advise the bots they are duplicate .. They will figure it out and that is when they dont like it .
Hope that clears up your doubts , if you need a more specific answer . We will need more info on what exactly you are trying to achieve .

Thats perfect. Thank you.
The only issue I have is that in this scenario I am going to have to use close to duplicate title tags, h1's and URL's. Since each page is going after the exact same keyword. But if you are saying that Google has no problem with ranking these 2 pages because one of them is on a sub-domain than that solves at least one problem.
-
Google treats sub domains as a different site in a sense.. and hardly ever passes any benefit of the root domain to the sub domain. Usually, your root domain would rank higher than the sub domain.. naturally.. unless your sub domain has better seo on/off site.
If both pages were equal it would show both. but would have to choose which one would receive the better ranking.
-
Do not create exact copies of the site.
Google will not choose they will just "punish" your site and have it dropped.
If you must create a copy of the site, make it unique.
It is very important
-
I guess I should explain a little more. I realize that it is going to be duplicate content but would Google have to choose between the two pages as which one to show or would the sub-domain page be allowed to rank as well as the root domain page? All thing being equal of course.
E.g. A tractor re-seller sells John Deere Tractors. They have since signed a white label deal to be the official reseller of John Deere Tractors. They have a page for the riding model x at www.example.com/riding-mower-x that ranks very well. But they also have a new white label page now for the exact same mower. They want both pages to rank and not force google to choose which page to show. Would Google look at the sub-domain page of ridingmowerx.example.com as a completely different site so that it would not have to choose and could rank both pages?
-
short answer is yes as long as the content is available for crawl that will be duplicaed content.
please elaborate of he goal of this duplication so I can try to tackle this problem

It is duplicate content either way across the world wide web. For example.. a blog posts an article, I take that article and post it to my blog.. that is considered duplicate content. Use this post by rand to help determine when to use sub domains!

Redirection of 100 domain to Main domain affects SEO?
Hi guys, An email software vendor managed by a different area of my company redirected 100 domains used for unsolicited email campaigns to my main domain. These domains are very likely to get blacklisted at some point. My SEO tool now is showing me all those domains as "linking" to my main site as do-follow links. The vendor states that this will not affect my main domain/website in any way. I'm highly concerned. I would appreciate your professional opinion about this. Thanks!!

Will we be penalised for duplicate content on a sub-domain?
Hi there, I run a WordPress blog and I use [community platform] Discourse for commenting. When we publish a post to Wordpress, a duplicate of that post is pushed to a topic on Discourse, which is on a sub-domain. Eg: The original post and the duplicated post. Will we be penalised for duplicating our own content on a subdomain? If so, other than using an excerpt, what are our options? Thanks!

Domain Authority... http://www.domain.com/ vs. http://domain.com vs. http://domain.com/
Hey Guys, Looking at Page Authority for my Site and ranking them in Decending Order, I see these 3 http://www.domain.com/ | Authority 62 http://domain.com | Authority 52 http://domain.com/ | Authority 52 Since the first one listed has the highest Authority, should I be using a 301 redirects on the lower ranking variations (which I understand how works) or should I be using rel="canonical" (which I don't really understand how it works) Also, if this is a problem that I should address, should we see a significant boost if fixed? Thanks ahead of time for anyone who can help a lost sailor who doesn't know how to sail and probably shouldn't have left shore in the first place. Cheers ZP!

Is it safe to redirect our .nl (netherlands) domain that we have just purchased to our .com domain?
Hi all! We've recently developed a German version of our website with German translation and now we have just purchased a .nl domain, but with this one, we want all of the copy to remain in English. Is it ok to redirect our .nl domain to our current .com website or will this give us bad SEO points? Thank you!

Should we move a strong category page, or the whole domain to new domain?
We are debating moving a strong category page (and subcategory, product pages) from our current older domain to a new domain vs just moving the whole domain. The older domain has DA 40+, and the category page has PA 40+. Anyone with experience on how much PR etc will get passed to a virgin domain if we just redirect olddomain/strongcategorypage/ to newdomain.com? If the answer is little to none, we might consider just moving the whole site since the other categories are not that strong anyway. We will use 301 approach either way. Thanks!

Menu & Sub menu structure - section specific sub menu?
Hi, At present I have a set of regions across the nav bar with drop downs for towns within these regions. This totals about 60 links. This set up is pretty much site wide and the site ranks well for many of these towns. However, this is quite a lot of links per page (without the page specific/content links) and I am wondering about having just a horizontal sub menu of towns appear below the nav bar only specific to the selected region. Do you think cutting down the number of menu links will be beneficial to the content page's ranking. Sorry if that isn't very clear, can't think of a better way of putting it. TIA,

Merging Domains... Sub-domains, Directories or Seperate Sites?
Hello! I am hoping you can help me decide the best path to take here... A little background: I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues. These three domains are PR4, PR4, PR5 and contain hundreds of unique articles. Here's the question... They want to move these three sites **to their main company site (PR4) and create sub domains for each one. ** I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective. Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this? Thanks in advance for the help! SD P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

Penalty for using expired domain?
I was wondering if anyone has any experience using dropped/expired domains with old "clean" backlinks for new sites. Is there be a penalty for doing this (with good intent)? Worth a reconsideration request?
