- We want to increase the value of some of our important images by means of SEO, and
- we want to start serving them from a different, i.e. cookieless, domain.
We want to go from www.example.com/images/1234.jpg to www.example.com/germany/bavaria/landscape.jpg which can easily be done via URL rewriting. Then on the other hand, we would like to serve the image from a completely different domain, let's say www.examplestatic.com/germany/bavaria/landscape.jpg, to save the overhead of sending the cookie from www.example.com.
Somehow I feel that this is not a good idea because I move the image away from the content by putting it on a different domain. Can anyone shed some light on this problem? Naturally, I would just use a different subdomain, e.g. img.example.com, but we already use subdomains for languages and our cookies are valid for all subdomains of example.com, so this won't help.
We are not so much worried about the search-ability of the images themselves, it's rather all about optimizing the pages they appear on. So a telling name/url for an image including a telling
alt attribute is probably a must have - but my question is about the domain part, if it's a bad idea to use a different domain.
But then again, the big players also have dedicated static content domains, e.g. images-amazon.com, ebaystatic.com, ... so there can't be anything wrong with it, can there?
I'd really appreciate any hints.
