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!

What's your proudest accomplishment in regards to SEO?
After many years in the industry, you come to realize a few things. One of of the biggest pain points for us at web daytona was being able to give clients a quick keyword ranking cost estimation. After multiple trial and error and relying on API data from one of the most reliable SEO softwares in our industry, we were able to develop an SEO tool that allows us to quickly and accurately get the estimated cost for a given keyword (s) using multiple variables. Most agencies can relate to that story. It’s something my colleagues and I at Web Daytona have been through before. Finding the cost and amount of time needed to rank for a keyword is a time consuming process. That’s why it’s a common practice to sell SEO packages of 5-10 keywords for about $1000-2000 / month. The problem is not all keywords are equally valuable, and most clients know this. We constantly get questions from clients asking: “how much to rank for this specific keyword?” It’s difficult to answer that question with a pricing model that treats the cost of ranking every keyword equally. So is the answer to spend a lot more time doing tedious in-depth keyword research? If we did we could give our clients more precise estimates. But being that a decent proposal can take as long as 2-5 hours to make, and agency life isn’t exactly full of free time, that wouldn’t be ideal. That’s when we asked a question. What if we could automate the research needed to find the cost of ranking keywords? We looked around for a tool that did, but we couldn’t find it. Then we decided to make it ourselves. It wasn’t going to be easy. But after running an SEO agency for over a decade, we knew we had the expertise to create a tool that wouldn’t just be fast and reliable, it would also be precise. Fast forward to today and we’re proud to announce that The Keyword Cost Estimator is finally done. Now we’re releasing it to the public so other agencies and businesses can use it too. You can see it for yourself here. Keyword-Rank-Cost-Ectimator-Tool-by-Web-Daytona-Agency.png

Research on industries that are most competitive for SEO?
I am trying to see if there is a reputable / research-backed source that can show which industries are most competitive for search engine optimization. In particularly, I'd be interested in reports / research related to the residential real estate industry, which I believe based on anecdotal experience to be extremely competitive.

Do you use HREF lang tags when each page that is localised only exists in that language?
Hi, I have 2 questions I am seeking an answer for. We have a home page in english GB, we then also have products which are specifically served in US. For these pages where the phone number is american, the spelling is american, the address is american, do we need to implement href lang tags? The page isn't a version of another page in english, the page is only in the native language.Secondly, is it recommended to create a second home page and then localise that page for US users?I'd be really greatful if anyone has any pointers as googles forum doesn't explain best practice for this case (as far as I can tell).Many thanks

Can I use Schema zip code markup that includes multiple zip codes but no actual address?
The company doesn't have physical locations but offers services in multiple cities and states across the US. We want to develop a better hyperlocal SEO strategy and implement schema but the only address information available is zip codes, names of cities and state. Can we omit the actual street address in the formatting but add multiple zipcodes?

Can you, somehow, use dynamic number insertion on a click to call button (image)
Hello Moz! I have been beating my head against the wall for a few hours, and I am starting to get a headache. My question is simple: I am doing some work for a local salon, and we started a PPC campaign recently. It's very important that I get accurate ROI metrics from both our PPC efforts and Yelp advertising program, and the best way to do this is by using custom phone numbers and dynamic number insertion w/ CallRail to track phone calls being made to the salon. I can then cross reference the numbers used to call with the salon POS software to see what they spent, how many appts. they booked, etc. A VERY large portion, the majority in fact, of traffic comes from mobile, and in the past I had a big, fat, beautiful CTA click-to-call button that showed the salon phone number. However, I have found that with dynamic number insertion, and my near non-existent programming skills, it is impossible to have the number dynamically insert into an href image. Sooooo...any ideas on how to do this, or is it just not possible????

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

Subdomain for ticketing of a client website (how to solve SEO problems caused by the subdomain/domain relationship)
We have a client in need of a ticketing solution for their domain (let's call it www.domain.com) which is on Wordpress - as is our custom ticket solution. However, we want to have full control of the ticketing, since we manage it for them - so we do not want to build it inside their original Wordpress install. Our proposed solution is to build it on tickets.domain.com. This will exist only for selling and issuing the tickets. The question is, is there a way to do this without damaging their bounce rate and SEO scores?
Local Website Optimization | | Adam_RushHour_Marketing
Since customers will come to www.domain.com, then click the ticketing tab and land on tickets.domain.com, Google will see this as a bounce. In reality, customers will not notice the difference as we will clone the look and feel of domain.com Should we perhaps have the canonical URL of tickets.domain.com point to www.domain.com? And also, can we install Webmaster Tools for tickets.domain.com and set the preferred domain as www.domain.com? Are these possible solutions to the problem, or not - and if not, does anyone else have a viable solution? Thank you so much for the help.0
