Does image domain name matter when using a CDN?
-
Has anyone does studies on using a different CDN domain name for images on a site? Here is an example:

or
http://cdn.mydomain.com/image.jpg>
mydomain.com ranks highly and many images show up in Google/Bing image searches. Is there any actual data that says that using your real domain name for the CDN has benefits versus the default domain name provided by the CDN provider? On the surface, it feels like it would, but I haven't experimented with it.

No, I understand. Thanks for jumping in. The only reason why said it was a uglier subdomain, just to express that - even that didn't have a impact impressions, traffic, or CTR on images in my case.
Note, I get 80k+ UV a month and I spend more time monitoring traffic sources and do date comparisons than I should. I have alerts that tell me if I loose x% of traffic on a landing page.
As you can see - a lot of GB - we get a lot of image traffic - no impact, with my ugly url that I wont even make a effort to change.

It might be an ugly url but the content is still on your domain. In the question above it's about the image on their domain vs on the CDN's domain.
PS: didn't mean to hijack this question, I am also very interested to know the answer for the same question

WP engine is a wonderful host I use them as well.
A content delivery network will have 0 negative effect because of the way the code has changed on your website.
Simply use a C name. Or don't it really doesn't matter
for instance you could have www.example.com
that in your DNS
create a C name cdn.example.com to the right allow for username-wpengine.domain.com
then everything looks like CDN.example.com
I believe WP engine will change that for you even however you guys are worried about things that do not matter
a content delivery network will make your website much faster and regardless of if you think the code is ugly or not
it does not make a difference nothing negative will happen only good things happen when you use a CDN I strongly suggest you use them on pretty much anything and do not worry about the coding.
I have a lot of sites with content delivery networks and every one of them ranked better after using CDN than before.
Sincerely,
Thomas

No, I recently switched to wpengine ( http://moz.com/perks - we get 4 months free ) and they have a CDN. I haven't noticed any impact on my image results/impressions and the url for the image is pretty ugly like: username-wpengine.domain.com/2013/05/image.jpg or something like that.
From what I seen, I dont think that matters. I hope that helps.

Truncated product names
Due to the restraints of category page layout many of the products in certain categories have the product titles truncated, in some cases missing off 2-5 words depending on the product in question. The product name which displays on the category page is lifted straight from the product page itself, so not possible to do something like "product name including spec..." to place ... to indicate a bit more. I'm assuming not but just wanted to check that Google will not frown on this. Text is not being hidden it just does not render fully in the restricted space. So there is a scenario of 'bits of' text in the source not displaying on the rendered page.

Can I use a 301 redirect to pass 'back link' juice to a different domain?
Hi, I have a backlink from a high DA/PA Government Website pointing to www.domainA.com which I own and can setup 301 redirects on if necessary. However my www.domainA.com is not used and has no active website (but has hosting available which can 301 redirect). www.domainA.com is also contextually irrelevant to the backlink. I want the Government Website link to go to www.domainB.com - which is both the relevant site and which also should be benefiting from from the seo juice from the backlink. So far I have had no luck to get the Government Website's administrators to change the URL on the link to point to www.domainB.com. Q1: If i use a 301 redirect on www.domainA.com to redirect to www.domainB.com will most of the backlink's SEO juice still be passed on to www.domainB.com? Q2: If the answer to the above is yes - would there be benefit to taking this a step further and redirect www.domainA.com to a deeper directory on www.domianB.com which is even more relevant?

ie. redirect www.domainA.com to www.domainB.com/categoryB - passing the link juice deeper.0 -
How can you promote a sub-domain ahead of a domain on the SERPs?
I have a new client that wants to promote their subdomain uk.imagemcs.com and have their main domain imagemcs.com fall off the SERPs. Objective? Get uk.imagemcs.com to rank first for UK 'brand' searches. Do a search for 'imagem creative services' and you should see the issue (it looks like rules have been applied to the robots.txt on the main domain to exclude any bots from crawling - but since they've been indexed previously I need to take action as it doesn't look great!). I think I can do this by applying a permanent redirect from the main domain to the subdomain at domain level and then no-indexing the site - and then resubmit the sitemap. My slight concern is that this no-indexing of the main domain may impact on the visibility of the subdomains (I'm dealing with uk.imagemcs.com, but there is us.imagemcs.com and de.imagemcs.com) and was looking for some assurance that this would not be the case. My understanding is that subdomains are completely distinct from domains and as such this action should have no impact on the subdomains. I asked the question on the Webmasters Forum but haven't really got anywhere

Image search and CDNs
Hi, Our site has a very high domain strength. Although our site ranks well for general search phrases, we rank poorly for image search (even though our site has very high quality images). Our images are hosted on a separate CDN with a different domain. Although there are a number of benefits to doing this, since they are on a different domain, are we not able to capitalize on our my site's domain strength? Is there any way to associate our CDN to our main site via Google webmaster tools? Has anyone researched the search ranking impacts due to storing your images on a CDN, given that your domain strength is very high? Curious on people's thoughts?

Mobile Domain Setup
Hi, If I want to serve a subset of pages on my mobile set from my desktop site or the content is significantly different, i.e. it is not one to one or pages are a summarised version of the desktop, should I use m.site.com or is it still better to use site.com? Many thanks any help appreciated.

Subdomain and Domain Rankings
I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league) when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks

Starting a new product, should we use new domain or subdomain
I'm working with a company that has a high page rank on it's main domain and is looking to launch a new business / product offering. They are evaluating either creating a subdomain or launching a brand new domain. In either case, their current site will link contextually to the new site. Is there one method that would be better for SEO than the other? The new business / product is related to the main offering, but may appeal to different / new customers. The new business / product does need it's own homepage and will have a different conversion funnel than the existing business.
