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.

Company name ranking
Hi all, I hope somebody can share their thoughts on the below. A web designer launched my client's new website and I have been tasked with the SEO. I was approached with an immediate problem, www.clientswebsite.co.uk was ranking 9th for their company name after being indexed by Google. The search results above www.clientswebsite.co.uk were related to my client but not all, for example a direct competitor was also ranking. I have been working on the SEO for 2-3 weeks and I just managed to get to 3rd position for the company name, and then www.clientswebsite.co.uk disappeared from page 1! And now instead, an irelevant sub page is now ranking for the company name on page 2 (a contact page). I have checked and the home page is still indexed (did a site: check). The only problem software picks up is a redirect chain (http://homepage -> http://www.homepage -> https://homepage) the web developers said it wouldn't impact rankings (when I asked them to edit the htaccess file to fix it) I've listed below the SEO tasks I completed whilst attempting to rank the company name: I set up analytics and webmaster tools, in which I set up preferred domain (www) Added a sitemap Edited meta data making sure company name was included I contacted the websites above www.clientswebsite.co.uk that were relevant and asked them to place a link linking to their new website, I was successful with a couple of these. I placed www.clientswebsite.co.uk on all of their social media profiles I reformatted headers on their home page, making sure the H1 included my client's company name I found 2 extra versions of my client's home page (not exact copies, but very similar content) that had been published, so I decided to 301 redirect these to the correct home page Activated SSL and forced to HTTPS I would really appreciate it if anyone could share their thoughts here, whether it be explanations or possible solutions Adam

WooCommerce category naming conventions
I am managing a woocommerce store selling prescription glasses/spectacles. We have a lot of categories with similar names and I want to adopt the best possible naming convention to get the best from search. So we have a number of similar categories for both Men's and women's glasses. Currently they are named as follows: Women's Glasses-Women's Rimless Glasses
Technical SEO | | SushiUK
-Women's Semi Rimless Glasses
-Women's Plastic Glasses
-Women's Metal Glasses
-Women's Retro Glasses Currently, this results in the following URL structure for sub categories: https://www.glassesonspec.co.uk/product-category/womens-glasses-2/womens-rimless-glasses/ (For some reason WooCommerce is adding -2 to the end of the primary category name, it will not let me change it for some reason, this is the subject of a further investigation!) So first question, is there too much duplication of the word glasses on the sub items? for example, should they read; Women's Glasses
-Rimless
-Semi Rimless
-Plastic
-Metal
-Retro Hence giving this URL structure: https://www.glassesonspec.co.uk/product-category/womens-glasses-2/rimless/ OR, should we change the top level category name to just Women's and let the sub categories complete the picture?: Women's
-Rimless Glasses
-Semi Rimless Glasses
-Plastic Glasses
-Metal Glasses
-Retro Glasses Giving this example URL structure: https://www.xxxxxxxxxxxxx.co.uk/product-category/womens/rimless-glasses/ This would solve my hyphenation problem, however my fear is the top level category on it's own is not descriptive enough when viewed as stand alone: https://www.xxxxxxxxxxxxx.co.uk/product-category/womens/ The second part of my question relates to how to deal with the change in URL structure. I am using Yoast Premium, so will that pick up the changes and automatically redirect to the new one as it does when done manually? Or will I need to take a different approach using HTACCESS commands? I hope the above makes sense, Many thanks, Bob0 -
How well do .ltd.uk domain names rank?

Effective use of hReview
Hi fellow Mozzers! I am just in the process of adding various reviews to our site (a design agency), but I wanted to use the ratings in different ways depending on the page. So for the home page and the services (branding, POS, direct mail etc) I wanted to aggregate relevant reviews (giving us an average of all reviews for the home page, an average of ratings from all brand projects and so on). Then, I wanted to put specific reviews on our portfolio pages, so the review relates specifically to that project. This is the easiest to do as the hReview generator is geared up for reviews that come from one source, but I can't find a way of aggregating the star ratings to make an average rating rich snippet. Anyone know where I can get the coding for this? Thanks in advance! Nick.

What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?
Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like: staging.domain.com
Technical SEO | | fthead9
User-agent: *
Disallow: / in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.0 -
Why are old versions of images still showing for my site in Google Image Search?
I have a number of images on my website with a watermark. We changed the watermark (on all of our images) in May, but when I search for my site getmecooking in Google Image Search, it still shows the old watermark (the old one is grey, the new one is orange). Is Google not updating the images its search results because they are cached in Google? Or because it is ignoring my images, having downloaded them once? Should we be giving our images a version number (at the end of the file name)? Our website cache is set to 7 days, so that's not the issue. Thanks.
