Image URLs changed 3 times after using a CDN - How to Handle for SEO?
-
Hi Mozzers,
Hoping for your advice on how to handle the SEO effects an image URL change, that changed 3 times, during the course of setting up a CDN over a month period, as follows:- (URL 1) - Original image URL before CDN:www.mydomain.com/images/abc.jpg
- (URL 2) - First CDN URL (without CNAME alias - using WPEngine & their own CDN):
username.net-dns.com/images/abc.jpg - (URL 3) - Second CDN URL (with CNAME alias - applied 3 weeks later):
cdn.mydomain.com/images/abc.jpg
When we changed to URL 2, our image rankings in the Moz Tool Pro Rankings dropped from 80% to 5% (the one with the little photo icons).
So my questions for recovery are:
- Do I need to add a 301 redirect/Canonical tag from the old image URL 1 & 2 to URL 3 or something else?
- Do I need to change my image sitemap to use cdn.mydomain.com/images/abc.jpg instead of www.?
Thanks in advance for your advice.

Sorry I missed this follow-up earlier. Within the site map you'll want to change the http://WWW to http://CDN for these image files. The www version of your site, and the cdn server are on two different IPs / server. You want images to be serving from the CDN one.
For 2, if you do use 301 redirection I'd recommend scripting it so that the script inspects whether or not it's an image file and then applies the cdn change. A pro in your area that works with REgex and htaccess will be able to guide you through that.
The username.net-dns.com thing... That's not your server is it? You can't apply redirects on servers outside of your control. Cheers!

Hi Ryan,
Thanks for your answer - Sorry I didn't mean about the URL for the location of the sitemap - I think my question wasn't clear - may I rephrase it:(1) Inside my image sitemap, the urls serve off the www. subdomain as bolded in the example below (not .cdn). I'm assuming this setup is correct as this was auto-generated by an Image Sitemap Generator - does the below image:loc look correct to you?
<url><loc>http://www.bosphorusyacht.com/yachts/</loc>
image:imageimage:lochttp://**WWW.**bosphorusyacht.com/wp-content/uploads/2010/09/istanbul-boat-rental.jpg</image:loc></image:image></url>(2) For a 301 image redirect would I set it up like this:
Redirect 301 /wp-content/uploads/2010/09/istanbul-boat-rental.jpg
http://**WWW.**bosphorusyacht.com/wp-content/uploads/2010/09/istanbul-boat-rental.jpgOR
Redirect 301 /wp-content/uploads/2010/09/istanbul-boat-rental.jpg
http://**CDN.**bosphorusyacht.com/wp-content/uploads/2010/09/istanbul-boat-rental.jpgOR
How would I 301 this one?: username.net-dns.com/images/abc.jpg
Hope you can advise one last time - thank you!

Right. Not everything is going to be served from cdn. It's most likely setup for your images so your sitemap will still reside on www. Make sure to point to the front end files though as those are the publicly accessible ones.

Hi Ryan,
Thanks for your reply and advice. I've read the guidelines and will follow those. But I wonder if you can clarify an issue on implementing them that is not answered there:On my site the images in 'Backend' (edit/admin/code view) start with WWW.mydomain... and in 'Frontend' (actual published view in browser) they start with CDN.mydomain...
So my question is, do I use the Backend or Frontend (www. or cdn.) for the URL in both image sitemaps and in 301 redirect final destination?
My current sitemap for example seems to be using www rather than cdn. : http://www.bosphorusyacht.com/sitemap-image.xml
Thanks for your help!

You're on it. Redirecting to the new image source and submitting a new sitemap pointing to the URL 3 location for your images will be big steps in the right direction. Be sure to follow the instructions here for your sitemap: https://support.google.com/webmasters/answer/178636 as well as reviewing image publishing guidelines: https://support.google.com/webmasters/answer/114016. Cheers!

Subdomain vs. Separate Domain for SEO & Google AdWords
We have a client who carries 4 product lines from different manufacturers under a singular domain name (www.companyname.com), and last fall, one of their manufacturers indicated that they needed to move to separate out one of those product lines from the rest, so we redesigned and relaunched as two separate sites - www.companyname.com and www.companynameseparateproduct.com (a newly-purchased domain). Since that time, their manufacturer has reneged their requirement to separate the product lines, but the client has been running both sites separately since they launched at the beginning of December 2016. Since that time, they have cannibalized their content strategy (effective February 2017) and hacked apart their PPC budget from both sites (effective April 2017), and are upset that their organic and paid traffic has correspondingly dropped from the original domain, and that the new domain hasn't continued to grow at the rate they would like it to (we did warn them, and they made the decision to move forward with the changes anyway). This past week, they decided to hire an in-house marketing manager, who is insisting that we move the newer domain (www.companynameseparateproduct.com) to become a subdomain on their original site (separateproduct.companyname.com). Our team has argued that making this change back 6 months into the life of the new site will hurt their SEO (especially if we have to 301 redirect all of the old content back again, without any new content regularly being added), which was corroborated with this article. We'd also have to kill the separate AdWords account and quality score associated with the ads in that account to move them back. We're currently looking for any extra insight or literature that we might be able to find that helps explain this to the client better - even if it is a little technical. (We're also open to finding out if this method of thinking is incorrect if things have changed!)

Is CNAME / URL flattening a bad practice?
I recently have moved a number of websites top a new server and have made the use of CNAME / URL flattening (I believe these are the same?). A network admin had said this is an unrecommended practice. From what I have read it seems flattening can be beneficial for site speed and SEO even if very little.

301 or 302 Redirects with locale URLs?
Hi Mozers, I have a bit of a tricky question I need some help answering. My agency are building a brand new website for a client of ours which means changing the domain name (yay...). So! I have my 301's all ready to go for the UK locale, however, the issue I have is that the site will also eventually have French, German and Spanish locales - but these won't be ready to go until later this year. We will be launching in just English for September. The current site already has the French and German locales on it as well. Just to make sure I'm being clear, the site will be www.example.com for launch, but by lets say November, we will also have a www.example.com/fr/ and www.example.com/de/ site launched too. So what do I do with the locale URLs? As I said above, the exisitng site already has the French and German locales on it, so I don't particularly want to redirect the /fr/ and /de/ URLs to the English homepage, as I will want to redirect them to the new URLs in November, and redirecting more than once is bad for SEO right? Any ideas? Would 302s maybe be the best suggestion? Thanks! Virginia

Title Tag, URL Structure & H1 for Localization
I am working with a local service company. They have one location but offer a number of different services to both residential and commercial verticals. What I have been reading seems to suggest that I put the location in URLs, Title Tags & H1s. Isn't it kind of spammy and possibly annoying user experience to see location on every page?? Portland ME Residential House Painting Portland ME Commercial Painting Portland Maine commercial sealcoating Portland Maine residential sealcoating etc, etc This strikes me as an old school approach. Isn't google more adept at recognizing location so that I don't need to paste it In H1s all over the site? Thanks in advance. PAtrick

Does the Location of my Server effect my SEO?
Does the geographic Location of my Server effect my SEO? HELP US! We are arguing for 3 weeks already. My partner has mentioned multiple times in the past that "since 2013 google does not require your server to be in the country you are targeting for seo"
Local Website Optimization | | DanielBernhardt
And that actually all they care about is if its a good and fast server - not where its physically located in the world. I am a strong believer that the geographic location of your server directly effects your SEO ranking... lets say if you want to target www.google.ru for your seo, best you have a server located in Russia for hosting your website.. WHO IS RIGHT? Choose the winner and base the facts.
If anybody has the correct answer and information to base it on it will help us alot - and maybe even spare some unnecessary violent between us two! we found some articles across the web, sadly they are all dated back to 2012.... Thanks in Advance for all the help guys!0 -
Are there any suggestions when you completly redesign your web page keeping the same domain but change the host? I want it to go smoothly and want to avoid the rankings we already have including sub pages.
I am currently having our website completely redone by a design company. Are there any suggestions on this process as to not lose the rankings we currently have for our site? The domain will remain the same however we are planning on changing our host. We also have a good amount of sub domains that the web company will not be changing for us.
