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.

CcTLD + Subdirectory for languages
Hey, a client has as .de domain with subdirectories for different languages, so domain.de/de, domain.de/en, domain.de/fr etc. hreflang Tags are implemented, so each subdirectory of each language references to the other languages, so for domain.de/en it is: My question is about the combination of ccTLD + language subdirectory. Do you think this is problematic for Google and should be replaced with .com + language subdirectory? We have lots a high quality domains (from countries with corresponding languages) linking to .de/de and .de/en, some links on .de/fr & .de/es and 0 links pointing to .de/cn. Thanks in advance!

Spanish United States Vs Puerto Rico Hreflang
Hey Moz, So we are trying to figure out weather it is the same if we have Hreflang for "US-ES" vs "US-PR", IF we do "US-PR" for Puerto Rico for its own links we then have to create 3 parts to our site, PR Spanish PR English US Spanish We looked at Apple as an example and they had a "Latin America" for their Hreflang and labeled everything has either "es-419" is that the same concept as having just "us-es" for Puerto Rico? ( see attached screenshot ) We are trying to figure out what would be more effective and weather or not "US-ES" search results will appear for Puerto Rico also. PZVwg16

Removing site subdomains from Google search
Hi everyone, I hope you are having a good week? My website has several subdomains that I had shut down some time back and pages on these subdomains are still appearing in the Google search result pages. I want all the URLs from these subdomains to stop appearing in the Google search result pages and I was hoping to see if anyone can help me with this. The subdomains are no longer under my control as I don't have web hosting for these sites (so these subdomain sites just show a default hosting server page). Because of this, I cannot verify these in search console and submit a url/site removal request to Google. In total, there are about 70 pages from these subdomains showing up in Google at the moment and I'm concerned in case these pages have any negative impacts on my SEO. Thanks for taking the time to read my post.

Removed Subdomain Sites Still in Google Index
Hey guys, I've got kind of a strange situation going on and I can't seem to find it addressed anywhere. I have a site that at one point had several development sites set up at subdomains. Those sites have since launched on their own domains, but the subdomain sites are still showing up in the Google index. However, if you look at the cached version of pages on these non-existent subdomains, it lists the NEW url, not the dev one in the little blurb that says "This is Google's cached version of www.correcturl.com." Clearly Google recognizes that the content resides at the new location, so how come the old pages are still in the index? Attempting to visit one of them gives a "Server Not Found" error, so they are definitely gone. This is happening to a couple of sites, one that was launched over a year ago so it doesn't appear to be a "wait and see" solution. Any suggestions would be a huge help. Thanks!!

Robots.txt on http vs. https
We recently changed our domain from http to https. When a user enters any URL on http, there is an global 301 redirect to the same page on https. I cannot find instructions about what to do with robots.txt. Now that https is the canonical version, should I block the http-Version with robots.txt? Strangely, I cannot find a single ressource about this...

Title Tag vs. H1 / H2
OK, Title tag, no problem, it's the SEO juice, appears on SERP, etc. Got it. But I'm reading up on H1 and getting conflicting bits of information ... Only use H1 once? H1 is crucial for SERP Use H1s for subheads Google almost never looks past H2 for relevance So say I've got a blog post with three sections ... do I use H1 three times (or does Google think you're playing them ...) Or do I create a "big" H1 subhead and then use H2s? Or just use all H2s because H1s are scary? 🙂 I frequently use subheads, it would seem weird to me to have one a font size bigger than another, but of course I can adjust that in settings ... Thoughts? Lisa
