In the past any large company could use subdomains as an effective reputation management strategy. As eBay and others have aggressively used subdomains to dominate branded AND unbranded search results, and Google has improved their sitelinks technology, any relevancy gain by treating subdomains as a separate site has gone away. Google is going to start treating subdomains like subfolders, and limit the number of results from any site to two.
There is still an upside to using subdomains because they allow you to feature standout content, but that upside relates to how marketable the content on that subdomain is, whereas in the past using lots of subdomains allowed eBay to get 20 of the top 30 listings for some queries, even if the subdomain was recycled garbage.
This move adds value to regionalizing sites and creating niche brands (like MobileCrunch), since currently I believe ebay.ca and ebay.com will be seen as two separate sites. If sites are too aggressive with regionalization or creating niche brands and start double dipping that way then Google might eventually look to devalue that move as well, although that will be more of a challenge because it would create a lot of collateral damage.

It's funny. I believe Google has probably already been doing this for some time (prior to the announcement). We have a site that makes use of subdomains instead of folders, and about a month ago, it would start to only return 2 results instead of one. To some degree it was a problem, on the other hand though, it does prevent our site from dominating the top 10 (which from a search user standpoint, I think is good).
Hi Aron,
As for the question to use subdomains vs folders.
I can only find conflicting opinions everywhere I go.
But for an example such as this, which do you think is best for ranking or is there no difference?
Examples:
sports.mydomain123.com
life.mydomain123.com
world.mydomain123.com
or
mydomain123.com/sports
mydomain123.com/life
mydomain123.com/world
and
sports.mydomain123.com/football.html
sports.mydomain123.com/soccer.html
or
mydomain123.com/sports/football.html
mydomain123.com/sports/soccer.html
If you know where an answer is or have time to answer I really appreciate any help. I'll make sure I share this post!
I tried to spell that out in the above post, when I wrote
The key is to ensure the subdomains are logical breaks and the content level is (or intends to be) strong enough to be featured.
Hi Aaron,
One of my competitors is TopTenReviews and I consistently see them owning specific keyword phrases by using sub domains.
For example, if you do a search on Google for "video editing" they come up #1. I've tried a dozen keyword searches and each time they come up in the Top 3 by using subdomains: video-editing-software-review.toptenreviews. com
Seeing this in action, I feel like subdomains are the way to go because you can get your keyword phrase first in the domain name, while still using your existing domain name (which already has age on it and PR).
Can you share your latest thoughts on this? Are the results TopTenReviews are getting a fluke or a true indicator that subdomains are the way to go?
Thanks in advance for the help!
We give search strategy advice in our member forums. If we give it individualized, personalized, and free on the blog then it undermines our own business model.
Do you have some examples of this with a before and after? Is this "live" yet or only partially so? I'm looking at an example that is particularly of interest to me and don't see any difference.
Feel free to mail me to get the example I'm talking about.
Hi Greggles
I am still seeing 3 ebay listings on this search, but then there are only 1,600 results total according to Google for that search.
For brand related searches like SEO Book I am still seeing many results from my site. And I have 4 of the top 50 results in Google for SEO still.
This change and moving forward setting up the structure of a site really seems like a double-edge sword for me - and I'm sure other SEOs.
I'm a stickler for consistency and structure. In a perfect world I want to sub-domain a site to break apart relevant sections. Such as blog.company.com, careers.company.com, etc.
So if Google follows through with this, and I would like to rank in the top 10 for all these sections, in actuality I would have to do something such as companyblog.com, companycareers.com, etc?
Hi MrThePlague
You can still use subdomains and rank them all, but they all will not rank at the same time for the same queries. Everything beyond the top couple matching results for each query might get stripped out.
Matt must hate you lately..
Aaron said it the subdomain is for "standout content," and when it a repeat... I think just tricky. I have continued to see the tricky people get punished of time. When you focus on finding the shortcuts, the search engines find a way to stop you. I have enjoyed reading about all the companies lose page rank for many reasons as the less than good content was punished.
I hear many webmasters tell me or say how they can get traffic. I think, really wish I had about 50 good writers, to type into computers. I figure a good page makes 80 cents per year, and how do I afford to pay this writer.
A sub-domain used to recycle the same materials is not "Standout Content," it is tricky.
A good business is trusted, good content is trustworthy.
That depends on the topic and site. Many of mine do more than that per day.
If I'm not mistaken, I've seen discussion of this for a few years now. I think most of the filtration that takes place in this area is manual and usually occurs in the top search spaces. There is protocol for Hostnames and if a site matches the criteria for that protocol, then follow it. Whether or not Google is going to limit the number of results is a moot point.
The Hostname is a powerful part of the overall equation. Usually if a site holds a top position and there are hostnames below that, there is a good chance that any removal of the third and fourth references is no big deal. That top position will typically remain intact. Plus you have that second instance they refer to. That is what you want to work on. ;)
You can't be hogging the results all the time, be happy with that ATF spot you have!
For branded search results (ie: seobook OR seo book) you can hog away, but it is now much harder to get that 3rd and 4th listing for non-branded keywords.
