Subdomains & CDNs
-
I've set up a CDN to speed up my domain. I've set up a CNAME to map the subdomain cdn.example.com to the URL where the CDN hosts my static content (images, CSS and JS files, and PDFs).
www.example.com and cdn.example.com are now two different IP addresses.
Internal links to my PDF files (white papers and articles) used to be www.example.com/downloads but now they are cdn.example.com/downloads
The same PDF files can be accessed at both the www and the cdn. subdomain. Thus, external links to the www version will continue to work.
Question 1: Should I set up 301 redirects in .htaccess such as:
Redirect permanent /downloads/filename.pdf http://cdn.example.com/downloads/filename.pdf
Question 2: Do I need to do anything else in my .htaccess file (or anywhere else) to ensure that any SEO benefit provided by the PDF files remains associated with my domain?
Question 3: Am I better off keeping my PDF files on the www side and off of the CDN?
Thanks,
Akira

On your cdn, you have an option to disallow se's to index files on subdomains by robots.txt so you can keep a copy on cdn.example.com as well, and noindex it via robots.txt for better user experience

Yup...keep it simple...where possible

There are about a dozen PDFs and they are indexed.
I agree that it's probably better to play it safe and keep these files on www.
Thanks!

How many PDF files are we talking ? Are they indexed ? Is there unique text content or images that have text that google has OCR'D ? If yes, I would suggest keeping them on www and therefore keep it simple. Again, it depends how many PDF files in number as well as their size in gigs would make it an easy answer.

Duplicate Page Title & Content Penalty On Website Tonight Platform
I built my primary website on Website Tonight (WT) five years ago when I was a net newbie and I'm presently new to seomoz. The initial crawl indicated a problem with duplicate page title and duplicate content with my website home page in WT. It turns out that the WT platform makes you assign a file name to your homepage i.e: www.business.com/homepage.html that differs from the www.business.com that you want as your homepage url. Apparently the search engines are recognizing these identical pages as separate and duplicate. I know that the standard answer would be to just do a 301 redirect from the long file name to the short file name - end of story. But WT does not allow you to do 301 redirects and they also do not give you the ability to go into the htaccess file to fix this yourself manually. I spoke to the folks at WT tonight and they claim that they automatically do 301 redirects on the platform. But if this true then why am I getting the error message in seomoz? Does anyone know if this is a problem? If so, does anyone here have a fix? Thanks in advance. Sincerely - Bill in Denver

Name Servers & SEO
We have decided to create a few blogs and will eventually be linking to some of our clients. I have domain privacy and different class C addresses for each of my domains. But the name servers area all the same. Ex: If we create an article for one client on all 5 blogs, will the name servers be a problem?

301 Redirect & re-use
I have an old site which is being moved to a new tld due to re-branding. I understand I would do a series of 301 redirects from the pages of the old site to capture the authority and move to the new site. However, at some point in the future (probably 1-2 years) we may want to re-use the old site again for a different brand (it has a good brand, just not for what we're going after). Question is - can a redirected site be re-used at some point in the future? And if so, which site would new authority (links, etc.) go to?

Subdomains & SEO
Exact match domains are great for ranking but what about domains which contain just half of the full phrase being targeted? eg. If you owned the domain rentals.co.uk but wanted to target the search term "car rentals" Regarding backlinks, would it be best to link back to your rentals.co.uk homepage (using anchor text "car rentals") or to one of the following: a) www.rentals.co.uk/car-rentals b) car.rentals.co.uk AND 301 redirect to www.rentals.co.uk c) car.rentals.co.uk AND 301 redirect to www.rentals.co.uk/car-rentals

Blog on a subdomain vs subfolder?
Hi, Does anyone have data to show that a subfolder is better than a subdomain for a blog? From what I've read, it sounds like both are a viable option but you choose subdomain if you want to build your blog as a distinct entity. Do you get ranked more quickly with a subfolder? Do you see X% more lift? Has anyone tested or seen tests around this subject? Any input is appreciated! Thanks in advance.
