Moving Images to Subdomain: SEO Impacts
-
For sever work- load enhancements we are planning to move our images to a sub-domain. so the files would be located at something like
Rather than domain.com/images/
We are a large Ecommerce site so we have a lot of images. These will be self hosted so we are not using a CDN. I'm hoping someone has done the same and if there were any steps they had wished they had taken before making the move/ if they noticed any traffic impacts things like that.

Hi Jared,
Webmaster tools is indeed the only way you can check what the % of image search is (you can also see it in Google Analytics if you have linked both accounts - it is the same data however as it's measured via webmaster tools). Solution you put in place seems a very good idea.

Dirk,
Thanks for your quality response! Within webmaster tools we get a decent amount of clicks from image search but still less then 10% of our overall organic traffic. Without being able to filter out that the traffic is coming from an image in GA I am not sure how else I can gauge how much organic traffic we are getting from images. We came up with the solution leaving our current images at their location but moving new images to the subdomain. Because much of our inventory changes with new seasonal lines we are adding lots of new products so those images will all be hosted on the sub-domain.
Thanks,

Do you get al lot of traffic from image search? If not, I don't think it really matters, there are thousands of site who are using the same setup as you.
if you get a lot of traffic from image search you need to be careful. Never moved from main domain to sub domain, but did a recent migration of a site where 80% of traffic came from image search. All the images were moved to a new folder.
In my experience, the image index is updated much slower than the normal index, and while google is quite fast to index the redirected urls it seems to need much more time for the images. On a previous migration we had the situation where the image thumbnails where still visible, but as soon you did preview the image the image didn't load as it had moved from it's original location. The problem with image search is that when this happened the position of the image remained in the results the site behind it changed (at that point we also discovered that an huge number of sites had stolen our original images).
To avoid this we now migrated the images to the new location and updated the links in the html, but we also kept the same images in the old location until we had the impression that they were no longer indexed.
this strategy seemed to work as unlike the first migration our results from image search were unaffected.
hope this helps
Dirk

Local SEO: Ste vs. Suite vs. #
Hi, I used the spelled out "Suite" in my local NAP, but sometimes it's been shortened to Ste by citation websites. I'm trying to remain consistent here Should I use Ste H, Suite H, or #H? This is a good article on it: http://localsearchforum.catalystemarketing.com/google-local-citations/1605-suite-vs-ste-vs-your-citation-addresses-2.html but I'd still like your opinion.

Local SEO: Links with the citations so should I slow down?
Hello, There seems to be some nofollow and dofollow links building as I add structured citations. Is this a reason to slow down the building citation process if you want the links to count? Do they help organic SEO?

Local SEO address question - adding a suite number for shared address for office building
Hi, I have a client that has an address that is shared for a few different businesses in the holistic health field. My client is a chiropractor. There is an eye doctor, massage therapist and acupuncturist aslo sharing the same address. It's a subburban setting with two buildings all sharing one address. In the interest of preventing any merged listings down the road, I recently added un unofficial suite number to his website and Google places business listing. I also did this for all of his online directory listings, and for Bing and Yahoo as well. Did I do the right thing here? It seems to be having a positive impact on his local SEO as far as I can tell. Or at least there has not been any negative impact in the last 6 months Your thoughts?

Dynamic image serving SEO
We often use images from a dynamic image server, to cater for image asset management, multiple sizes etc. Similar to Adobe's Scene7, although that came out after we chose our product. So widgets.com may have all its images with a URL like myimageserver.com?src=widgets/catalogue/productname.jpg;width=100;height=100;angle=90, instead of widgets.com/images/productname.jpg. A potential client wants to capitalise on traffic from Google image search. We could build an image sitemap, listing the images on each page. What should we place in the image:loc field? The code: myimageserver.com?src=widgets/catalogue/productname.jpg;width=100;height=100;angle=90 Apparently we have to verify the hosting site in Webmaster Tools, but I can't see where. I have a single Webmaster Tools account, where most of our sites are defined. Would I have to verify it for each site using the dynamic imaging program? Love to hear from anyone with solutions for getting images indexed when they are hosted at third-party dynamic imaging programs.
