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

      or

      ![](<a)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.rainyclouds.online/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.

                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!

                Google not Indexing images on CDN.

                My URL is: https://bit.ly/2hWAApQ We have set up a CDN on our own domain: https://bit.ly/2KspW3C We have a main xml sitemap: https://bit.ly/2rd2jEb and https://bit.ly/2JMu7GB is one the sub sitemaps with images listed within. The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: https://bit.ly/2FAWJjk. Yet, GWT still reports none of our images on the CDN are indexed. I ve followed all the steps and still none of the images are being indexed. My problem seems similar to this ticket https://bit.ly/2FzUnBl but however different because we don't have a separate image sitemap but instead have listed image urls within the sitemaps itself. Can anyone help please? I will promptly respond to any queries. Thanks

                Merge 2 websites into one, using a non-existing, new domain.

                I need to merge https://www.WebsiteA.com and https://www.WebsiteB.com to a fresh new domain (with no content) https://www.WebsiteC.com. I want to do it the best way to keep existing SEO juice. Website A is the companies home page and built with Wordpress Website B is the company product page and built with Wordpress Website C will be the new site containing both website A and B, utilizing Wordpress also. What is the best way to do this? I have research a lot and keep hitting walls on how to do it. It's a little trickier because it's two different domains going to a brand new domain. Thanks

                Redirect multiple domains to 1 domain or not?

                Hi there, I have client who has multiple domains that already have some PA and DA. Problem is that most websites have the same content and rank better on different keywords.
                I want to redirect all the websites to 1 domain because it’s easier to manage and it removes any duplicate content. Question is if I redirect domain x to domain y do the rankings of domain x increase on domain y? Or is it better to keep domain x separately to generate more referral traffic to domain y? Thanks in advance! Cheers

                Canonical homepage link uses trailing slash while default homepage uses no trailing slash, will this be an issue?

                Hello, 1st off, let me explain my client in this case uses BigCommerce, and I don't have access to the backend like most other situations. So I have to rely on BG to handle certain issues. I'm curious if there is much of a difference using domain.com/ as the canonical url while BG currently is redirecting our domain to domain.com. I've been using domain.com/ consistently for the last 6 months, and since we switches stores on Friday, this issue has popped up and has me a bit worried that we'll loose somehow via link juice or overall indexing since this could confuse crawlers. Now some say that the domain url is fine using / or not, as per - https://moz.rainyclouds.online/community/q/trailing-slash-and-rel-canonical But I also wanted to see what you all felt about this. What says you?

                301 Redirect with an Exact Domain name Match

                My Client had a site that ranked for a pretty competitive two word phrase, but for a variety of reasons had to transfer the site to a different domain name (with none of the previous keywords). We've 301'd everything just fine to the new site, but our traffic for that two word phrase, as well as related long tail traffic, is beginning to drop. Could the drop be related to something that we didn't do well in the transfer? Or is it due to the new domain name now not being an exact match? Sitenote question: Our Google Analytics is still set up for the former domain name and shows data just fine. Is there any reason to switch GA to the new domain? What are the pros/cons? Much thanks in advance!
