Microsite on subdomain vs. subdirectory
-
Based on this post from 2009, it's recommended in most situations to set up a microsite as a subdirectory as opposed to a subdomain. http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites. The primary argument seems to be that the search engines view the subdomain as a separate entity from the domain and therefore, the subdomain doesn't benefit from any of the trust rank, quality scores, etc. Rand made a comment that seemed like the subdomain could SOMETIMES inherit some of these factors, but didn't expound on those instances.
What determines whether the search engine will view your subdomain hosted microsite as part of the main domain vs. a completely separate site? I read it has to do with the interlinking between the two.

I think the footer is the best way to interlink the websites in a non-obtrusive way for users. This should make your main corporate site your top linking site to each subdomain - and this is something you should be able to verify in a tool like Google Webmaster Tools. I do not have any specific examples to support this, but this is a common web practice.
This is not 100% related, but Google recently suggested using Footer links as one way to associate your web content with your Google profile account:
http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=1408986
So you can figure if Google looks to footer links to associate authorship - they would likely do the same to relate sites together.

Hi Ryan,
Your question is quite interesting. I, myself, went through the article one more time. I have no facts to back up the following, but I hope that it will contribute. FIrst I would go and validate them on webmaster tools. If they are inteded to hit a certain market, I will select that geographical location. Also, I think you have litte to worry about. I imagine that google won't pass certain trust to subdomains, depending on the site. If the number of subdomains is considerable, I would say that they have pretty slim chances of getting some push from the main site. Take for example free webhosting services. They could rank and have decent page rank, if people show interest to the particular subdomain, but is highly unlikely taht to be caused by the authority of the main site.
I haven't seen free hosting subdomain rank well for a long time now. On the other hand you have student and academic accounts on university sites. They all go with subfolders and rank pretty well for highly specific topics. If I have to give a short answer, I would say that is the type of site that makes the difference for google. If your site is considers a casual business website and you are developing a new market then you might not have a problem. If you use sudbomains for specifying product, then you might be ok again.
Google use subdomain for all their major products. For Google pages they used a separate domain. They now redirects to a subdomain sites.google.com. However, they will never give subdomains for personal use. There might be something to that. They do a 301 redirect from a subdomain on googlepages.com to sites.google.com/site/. So what they offer is a 301 redirect to a sub-sub folder, located on a subdomain on Google.

Ok. That makes sense. The way our company would use it is having a microsite for specific, focused topics - large enough that warrant their own site. They are clearly part of our overall brand, unlike the Disney properties example. On each of these sites, there will almost always be a link back to the main/corporate website, usually in the footer.
Do you think having one or two links on every page pointing back to company.com would be sufficient to notify search engines that the two are associated, and ultimately give some search value to the subdomain hosted microsite from the main domain?
Are there any studies or evidence supporting any of this?
-
Interlinking is definitely a factor - but content is what matters.
Take the Disney brands that live on Go.com:
They all live on Go.com but Google surely knows they are really separate sites that cover different topics. Same for any blogspot.com, typepad.com, etc. hosted blog. The millions of blogs there cover a wide range of topics and search engines understand that they are not related just because they share the same host domain.
On the other end of the spectrum - if your site just has two subdomains - let's say www.website.com and blog.website.com ... which cover the same topics and link to one another, search engines would more likely associate those two addresses.

I don't have an answer to your question, but if you're looking for some more reading about subdomains vs. TLDs, here is a presentation given at MozCon: http://www.distilled.net/blog/seo/mozcon-international-seo/. The slideshow has some info about it, and a bunch of other good stuff.

Does an subdomain hosted offsite provide SEO value
We have a job board hosted through an applicant processing system which we've setup as a subdomain (jobs.ourcompany.com), most of the assets are hosted on our primary domain (ourcompany.com). My question is does having it hosted offsite provide any value? Do we get credit for that content being shared and distributed on the web or does the applicant processing system? As I see it the options are (correct me if I'm wrong): Host the job listings on our primary domain (ourcompany.com/jobs) and have it point to the application on the subdomain. Advertise the job listings pointing to the primary domain on the paid sites. The free job listing sites will automatically point to the sub-domain because the applicant processing system automatically submits them. Host the job listings entirely on the sub-domain applicant tracking system and link to it from our primary site navigation. Advertise the job listings to the sub-domain so that both free and paid point to the same place. Obviously the second one would be much easier just not sure on the technical side of our website getting credit by search engines as the one who has produced the content.

Meta Description VS Rich Snippets
Hello everyone, I have one question: there is a way to tell Google to take the meta description for the search results instead of the rich snippets? I already read some posts here in moz, but no answer was found. In the post was said that if you have keywords in the meta google may take this information instead, but it's not like this as i have keywords in the meta tags. The fact is that, in this way, the descriptions are not compelling at all, as they were intended to be. If it's not worth for ranking, so why google does not allow at least to have it's own website descriptions in their search results? I undestand that spam issues may be an answer, but in this way it penalizes also not spammy websites that may convert more if with a much more compelling description than the snippets. What do you think? and there is any way to fix this problem? Thanks!

Rel=Canonical, WWW vs non WWW and SEO
Okay so I'm a bit of a loss here. For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar. I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise? Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same? Or am I wrong and all that link juice and authority passes just the same?

Redirecting Root domain to subdirectory by IP addresses (country specific)
We are using Wordpress Multisite. so www.mysite.com is our English website and www.mysite.com/sub is our Chinese website Can I redirect Chinese visitors who type "www.mysite.com" to "www.mysite.com/sub" ? so we want to force redirection to www.mysite.com/sub if our website is visited by Chinese IP Address. I've realized that this is called GeoIP Redirection. and our hosting company already has those database, I guess my job is just to simply insert some code in .htacess My question is, would it affect our SEO later on? and what .htacess code is the best practice here?

Will errors on a subdomain effect the overall health of the root domain?
As stated in the question, we have 2 sub domains that contain over 2000 reported errors from SEOMOZ. The root domain has a clean bill of health, and i was just wondering if these errors on the sub-domains could have a negative effect on the root domain in the eyes of Google. Your comments will be appreciated. Regards Greg

Subdomain Removal in Robots.txt with Conditional Logic??
I would like to see if there is a way to add conditional logic to the robots.txt file so that when we push from DEV to PRODUCTION and the robots.txt file is pushed, we don't have to remember to NOT push the robots.txt file OR edit it when it goes live. My specific situation is this: I have www.website.com, dev.website.com and new.website.com and somehow google has indexed the DEV.website.com and NEW.website.com and I'd like these to be removed from google's index as they are causing duplicate content. Should I: a) add 2 new GWT entries for DEV.website.com and NEW.website.com and VERIFY ownership - if I do this, then when the files are pushed to LIVE won't the files contain the VERIFY META CODE for the DEV version even though it's now LIVE? (hope that makes sense) b) write a robots.txt file that specifies "DISALLOW: DEV.website.com/" is that possible? I have only seen examples of DISALLOW with a "/" in the beginning... Hope this makes sense, can really use the help! I'm on a Windows Server 2008 box running ColdFusion websites.

How to move my blog from subdomain to subfolder?
Not an unusual situation, I have a blog on blog.domain.com it has quite a few blog postings. The platform is old and will be scrapped, but the blog content itself is going to be moved to domain.com/blog. The current process is we are manually listing all linked to/content pages and we are going to 301 redirect them to their counterparts on the new blog. This is going to be a tedious process. A) Is there any way to automate the moving of the blog? B) What is the best way to do the massive 301 redirect, php headers, .htaccess? Should we move the individual pages with redirects, or redirect the domain in the .htaccess (this will be very difficult to match all the titles and file structure)?
