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!

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.

Thanks for the reply.
I think at the end of the day, yes it does help the user to have it all in one place.
And thanks for reiterating what I already thought... directories are better than sub-domains.
To be honest, this article is what had me questioning sub-directories in the first place: http://www.seobook.com/subdomains-google-panda

I agree with what you are thinking. The biggest effect would be if you can move them all onto one domain name (sub-folders) and setup 301 redirects. Keep hosting those domains forever since the 301s would stay only as long as you own the domains and continue to host them to serve the 301.
Moving them to sub-domains might be minimal / zero effect. I only see risk in doing that.
Ask yourself: Does it help the users in integrating all the content into one big website ?
-
Thanks for the reply.
I guess my biggest concerns are getting the biggest SEO bump I can by consolidating this content, but avoid any content farm penalties.
I was thinking subdomains would be safer, but provide the little to no SEO value.
Thanks again, that's a nice little checklist for moving domains.
-
Thanks for the reply. Yes, that was my thinking as well.
I have been concerned that I would be in essence creating a content farm because like I mentioned, these sites have hundreds or thousands of articles on them. And they publish 1-3 articles a day on average.
So you did this in early 2011 and found no ill effects from Panda?

Subdomains are often viewed by google as different domains. That means, links that hit one of them benefit that subdomain but transfer fractional benefit to other subdomains and to the root.
If this was my project I would use folders instead of subdomains. Your designer can make them look unique if that is needed, however, with them all being in the root directory all of the incoming links will benefit the entire site.
In early 2011 I redirected two subdomains of a busy site (one more powerful than the root domain) into folders and the results have been kickass. Kickass.
-
As long as your content is well structured amongst the sub-domains and root domain I can't see why there would be any issues. When making the change ensure that you:
- Tell Google that the URL is moving (do this via Google Webmaster Tools)
- Add permanent 301 redirects from the old URLs and point to their respective URLs on the new domain (this is to ensure that any backlinks the old websites had will pass some link juice through)
- Don't stop hosting the old domains for say 6 months.
- Run a backlink check on the old URLs and try get those websites (provided they are of good quality) to update the link to the new sub-domain. For those that don't update the 301 redirect will help.
Have fun!

Does it hurt your SEO to have an inaccessible directory in your site structure?
Due to CMS constraints, there may be some nodes in our site tree that are inaccessible and will automatically redirect to their parent folder. Here's an example: www.site.com/folder1/folder2/content, /folder2 redirects to /folder1. This would only be for the single URL itself, not the subpages (i.e. /folder1/folder2/content and anything below that would be accessible). Is there any real risk in this approach from a technical SEO perspective? I'm thinking this is likely a non-issue but I'm hoping someone with more experience can confirm. Another potential option is to have /folder2 accessible (it would be 100% identical to /folder1, long story) and use a canonical tag to point back to /folder1. I'm still waiting to hear if this is possible. Thanks in advance!

Moving to a new site while keeping old site live
For reasons I won't get into here, I need to move most of my site to a new domain (DOMAIN B) while keeping every single current detail on the old domain (DOMAIN A) as it is. Meaning, there will be 2 live websites that have mostly the same content, but I want the content to appear to search engines as though it now belongs to DOMAIN B. Weird situation. I know. I've run around in circles trying to figure out the best course of action. What do you think is the best way of going about this? Do I simply point DOMAIN A's canonical tags to the copied content on DOMAIN B and call it good? Should I ask sites that link to DOMAIN A to change their links to DOMAIN B, or start fresh and cut my losses? Should I still file a change of address with GWT, even though I'm not going to 301 redirect anything?

Unique domains vs. single domain for UGC sites?
Working on a client project - a UGC community that has a DTC model as well as a white label model. Is it categorically better to have them all under the same domain? Trying to figure which is better: XXX,XXX pages on one site vs. A smaller XXX,XXX pages on one site and XX,XXX pages on 10-20 other sites all pointing to the primary site. The thinking on the second was that those domains would likely achieve high DA as well as the primary, and would passing their value to the primary. Thoughts? Any other considerations we should be thinking about?

Robots.txt: how to exclude sub-directories correctly?
Hello here, I am trying to figure out the correct way to tell SEs to crawls this: http://www.mysite.com/directory/ But not this: http://www.mysite.com/directory/sub-directory/ or this: http://www.mysite.com/directory/sub-directory2/sub-directory/... But with the fact I have thousands of sub-directories with almost infinite combinations, I can't put the following definitions in a manageable way: disallow: /directory/sub-directory/ disallow: /directory/sub-directory2/ disallow: /directory/sub-directory/sub-directory/ disallow: /directory/sub-directory2/subdirectory/ etc... I would end up having thousands of definitions to disallow all the possible sub-directory combinations. So, is the following way a correct, better and shorter way to define what I want above: allow: /directory/$ disallow: /directory/* Would the above work? Any thoughts are very welcome! Thank you in advance. Best, Fab.

Can you redirect specific sub domain URLs?
ello! We host our PDFs, Images, CSS all in a sub domain. For the question, let's call this sub.cyto.com. I've noticed a particular PDF doing really well, infact it has gathered valuable external links from high authoritative sites. To top it off, it gets good visits. I've been going back and forth with our developers to move this PDF to a subfolder structure.
Intermediate & Advanced SEO | | Bio-RadAbs
For example: www.cyto.com/document/xxxx.pdf In my perspective, if I move this and set up a permanent redirect, then all the external links the PDF gathered, link juice and future visits will be attributed to the main website. Since the PDF is existing in the subdomain, I can't even track direct visits nor get the link juice. It appears in top position of Google as well. My developer says it is better to keep images, pdf, css in the subdomain. I see his point and an idea I have is to: convert the pdf to a webpage. Set up a 301 redirect from the existing subdomain to this webpage Upload the pdf with a new name and link to it from the webpage, so users can download if they choose to. This should give me the existing rank juice. However, my question is whether you can set up a 301 redirect for just a single subdomain URL to a folder structure URL? sub.cyto.com/xxx.pdf to www.cyto.com/document/xxxx.pdf?0 -
Splitting a Site into Two Sites for SEO Purposes
I have a client that owns a business that really could be easily divided into two separate business in terms of SEO. Right now his web site covers both divisions of his business. He gets about 5500 visitors a month. The majority go to one part of his business and around 600 each month go to the other. So about 11% I'm considering breaking off this 11% and putting it on an entirely different domain name. I think I could rank better for this 11%. The site would only be SEO'd for this particular division of the company. The keywords would not be in competition with each other. I would of course link the two web sites and watch that I don't run into any duplicate content issues. I worry about placing the redirects from the pages that I remove to the new pages. I know Google is not a fan of redirects. Then I also worry about the eventual drop in traffic to the main site now. How big of a factor is traffic in rankings? Other challenges include that the business services 4 major metropolitan areas. Would you do this? Have you done this? How did it work? Any suggestions?

Best approach to launch a new site with new urls - same domain
www.sierratradingpost.com We have a high volume e-commerce website with over 15K items, an average of 150K visits per day and 12.6 pages per visit. We are launching a new website this spring which is currently on a beta sub domain and we are looking for the best strategy that preserves our current search rankings while throttling traffic (possibly 25% per week) to measure results. The new site will be soft launched as we plan to slowly migrate traffic to it via a load balancer. This way we can monitor performance of the new site while still having the old site as a backup. Only when we are fully comfortable with the new site will we submit the 301 redirects and migrate everyone over to the new site. We will have a month or so of running both sites. Except for the homepage the URL structure for the new site is different than the old site. What is our best strategy so we don’t lose ranking on the old site and start earning ranking on the new site, while avoiding duplicate content and cloaking issues? Here is what we got back from a Google post which may highlight our concerns better: http://www.google.com/support/forum/p/Webmasters/thread?tid=62d0a16c4702a17d&hl=en&fid=62d0a16c4702a17d00049b67b51500a6 Thank You, sincerely, Stephan Woo Cude SEO Specialist scude@sierratradingpost.com
