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.

Forwarding a .org domain to a .com domain: any negative impact to consider?
Hello! I have a question I've been unable to find a clear answer to. My client's primary domain is a .com with a satisfactorily high DA. My client owns the .org version of its domain (which has a very low DA, I suppose due to inactivity) but has never forwarded it on. For branding/visibility/traffic reasons, I'd like to recommend they set up the .org domain to forward to the .com domain, but I wanted to ask a few questions first: 1. Does forwarding low-value DA domains to high-value DA domains have any negative authority/SEO impact? 2. If the .org domain was to be forwarded, am I correct that an SSL cert is not necessary for it if the .com domain has an SSL cert? Thanks in advance!

When you change your domain, How much time do I have to wait for google to return the traffic used to have?
Hello. 20 days ago, I changed my domain from uclasificados.net to uclasificados.com doing redirect 301 to all urls, and I started to loose rankings since that moment. I was wondering if changing it back could be the solutions, but some experts recommend me not to do that, because it could be worse. Right now I receave almost 50% of traffic I used to receave before, and I have done a lot of linkbuilding strategies to recover but nothing have worked until now. Even though I notified google of this change and I send again my new sitemap, I don't see that have improve my situation in any aspects, and I still see in webmastertools search stats from my last website (the website who used to be uclasificados.com before the change). What should I do to recover faster?

Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
Dear all, starting with my .htaccess file: RewriteEngine On
Technical SEO | | inlinear
RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

CDN Being Crawled and Indexed by Google
I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases. It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt? Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL. Thanks! Scott

Domain authority and keyword difficulty
I know there are too many variables for a certain answer, however do people take their domain authority into account when using keyword difficulty tool? I have a new domain which only has a score of seven at the moment. When using the keyword searching tool what is the maximum difficulty level keywords people would target initially? Obviously I would seek to increase the difficulty of the words over time but to start off its a hard choice between keywords which can be ranked for in a reasonable period of time and the keywords which are getting enough traffic to make the effort worthwhile.

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
