Subdomains vs. Subfolders for unique categories & topics
-
Hello,
We are in the process of redesigning and migrating 5 previously separate websites (all different niche topics, including dining, entertainment, retail, real estate, etc.) under one umbrella site for the property in which they exist. From the property homepage, you will now be able to access all of the individual category sites within.
As each niche microsite will be focused on a different topic, I am wondering whether it is best for SEO that we use subdomains such as category.mainsite.com or subfolders mainsite.com/category.
I have seen it done both ways on large corporate sites (ie: Ikea uses subdomains for different country sites, and Apple uses subfolders), so I am wondering what makes the most sense for this particular umbrella site.
Any help is greatly appreciated.
Thanks, Melissa

Its a no questions asked answer- SUBFOLDERS- by creating subdomains it's like saying your a separate entity and by doing that you will not be sharing all the value from the main domain and all the domains combined ie. pagerank, pages indexed, links, etc.

Yeah, I'm a subfolders kind of guy too, but here's SEOmoz weighing in on the subject of microsites and talking about the same sort of question you are - http://www.seomoz.org/blog/understanding-root-domains-subdomains-vs-subfolders-microsites

Definitely use subfolders!
By using your subfolders you pass all link juice and PR to the main domain which is mainsite.com. If you have say 10 subdomains, you are splitting the authority/link-juice/PR.
I know there are others who say Google passes the juice between a domain and subdomain, and it does pass some, but not all.
You cannot go wrong using subfolders. You build up one main domain, it's clean, user-friendly, etc...
SUBFOLDERS!

Forced to remove Categories with high volume & revenue
Hi everyone I've been forced to remove level 4 & 5 categories (e.g. example.com/level-2/level-3**/level-4/level-5/**) from our website, even though they're getting plenty of traffic, revenue and are ranking for some of our keywords. The argument is customers were using refinement/filters more than clicking into categories, and a new backend system is coming into the business and these need to be removed anyway. We've done this before and seen a drop in visibility, revenue & traffic in these areas, but we're going ahead with another batch of removals anyway. I was wondering if anyone has any experience in fixing a problem like this? I've been told the categories will not be returning and have to 301 them, so need to find a workaround to get eligible for ranking for these Keywords again. I've been looking at using the refinements to make it look like a category (change URL to a clean one, update Page Title, Meta Description, H1, remove text from core page, when refinement is clicked) but not sure what kind of knock-on effects this will have, if it even works! Hope you can help! I've probably missed some details so let me know if you need more info!!! Thanks

How to create a smooth blog migration from subdomain to subfolder main?
Hi mozzers, We have decided to migrate the blog subdomain to the domain's subfolder (blog.example.com to example.com/blog). To do this the most effective way and avoid impact SEO negatively I believe I have to follow this checklist: Create a list of all 301 redirects from blog.example.com/post-1 to example.com/post-1 Make sure title tags remain the same on main domain Make sure internal links remain the same Is there something else I am missing? Any other best practices? I also would like to have all blog post as AMPs. Any recommendations if this something we should do since we are not a media site? Any other tips on successfully implementing those types of pages? Thanks

Absolute vs. Relative Canonical Links
Hi Moz Community, I have a client using relative links for their canonicals (vs. absolute) Google appears to be following this just fine, but bing, etc. are still sending organic traffic to the non-canonical links. It's a drupal setup. Anyone have advice? Should I recommend that all canonical links be absolute? They are strapped for resources, so this would be a PITA if it won't make a difference. Thanks

Subdomained White-Label Sites
Wanted to pass along a specific use-case that I'm thinking through in the technical setup for a client. Site: http://www.abc.com is an ecommerce company that offers the ability to white-label a site so an affiliate can join and get access to the site, and ultimately get a cut of whatever is sold through that affiliate. So I join the site and get access to scott.xyz.com and can handle my business through that. From a technical standpoint, this is the proposed technical setup of the site. Canonical URLS will be set to www.xyz.com Pages on scott.xyz.com will be set to noindex, while the main www.xyz.com will be set to be indexed Webmaster Tools for scott.xyz.com will be set to have preferred domain of www.xyz.com scott.xyz.com will have separate robots.txt instructing to block crawl Questions Am I missing any steps in properly setting up the technical background of the subdomain sites? The use of subdomains isn't something that I am able to move away from. Will any links in to scott.xyz.com pass juice and authority to www.xyz.com, or does the noindex/nocrawl block that from happening? Is there anything else that I am missing? Thanks!

Lowercase VS. Uppercase Canonical tags?
Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase. Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue? Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's? I'm not too well versed in canonical tags and would love a little insight. Thanks!

Privacy Policy & T&C's SEO related question
With Adwords they request a Privacy Policy and T&C's sometimes for an Ad to be approved. Silly question I know but do you think Google looks out for pages like this to identity websites which are more genuine for organic? Thanks
