Hosting images on multiple domains
-
I'm taking the following from http://developer.yahoo.com/performance/rules.html
"Splitting components allows you to maximize parallel downloads. Make sure you're using not more than 2-4 domains because of the DNS lookup penalty. For example, you can host your HTML and dynamic content on
www.example.org
and split static components betweenstatic1.example.org
andstatic2.example.org"
What I want to do is load page images (it's an eCommerce site) from multiple sub domains to reduce load times.
I'm assuming that this is perfectly OK to do - I cannot think of any reason that this wouldn't be a good tactic to go with.
Does anyone know of (or can think of) a reason why taking this approach could be in any way detrimental.
Cheers mozzers.

Thanks Guys
I've got some developers to help me with the tech side so they'll be using the servers etc that they're used too.
Just wanted to check I wasn't dropping a massively obvious clanger on the SEO side.
Cheers for your help.
Alex.

Are you trying to rank your images in Google image search? If so, make sure the full path for each component stays the same.
As for general SEO, you're right on track. The performance boost from the parallel loading will be one more step to help you rank!

its really cheap to use a cdn like amazon rather than do it yourself

I like how Amazon's CloudFront does this. It uses a CNAME to route it to the closest download site. I would do the same. Use something like Round Robin to split your downloads up. Or use a cloud based host to do it for you.
As far as SEO goes, it shouldn't matter. Google will do its own DNS and caching.

Sub Domain Usage
I see that the gap uses gap.com, oldnavy.gap.com and bananarepublic.gap.com. Wouldn't a better approach for SEO to have oldnavy.com, bananarepublic.com and gap.com all separate? Is there any benefit to using the approach of store1.parentcompany.com, store2.parentcompany.com etc? What are the pros and cons to each?

Choosing root domain for a subdomain
We own two root domains in the .edu space. According to Open Site Explorer, one has a domain authority of 76, while the other has a DA of 94. We operate a collection of degree microsites as subdomains of the lower-ranking root domain, e.g. www.degreename.domain76.edu. All other things being equal, would these sites benefit if we migrated them to www.degreename.domain94.edu? The question seems to hinge on whether subdomains inherit any of the root domain's authority, and the answers I have seen to that question are "sometimes" and "maybe". Lastly, as an alternative, would we realize greater SEO improvements by moving the degrees to a directory structure under domain94, i.e. www.domain94.edu/degrees/degree-name? Thank you for your help!

How to See Image Metadata?
We sell 1000s of audiobooks and get our cover images and descriptions from the publisher’s sites. When I download a cover image such as this one (http://www.audiobooksonline.com/media/Alex-Cross-Run-James-Patterson.jpg)
Intermediate & Advanced SEO | | lbohen
I always rename and re-size it before installing at our Web store. Would this process result in any publisher’s metadata in the image we use at our Web store and/or anything else Google would not like?
Is there an online utility that would allow me to see metadata in our images?0 -
Is having all your media hosted on a sub-domain bad?
I just realized yesterday while doing some audit work on our site (which is still relatively new) that all of our audio assets are stored on a separate sub-domain. We are an eCommerce site that sells audio books, and every product page has a sample audio file to listen to. But all those files are stored on a sub-domain of the main site. "cdn-media.oursite.com". First, I understand that media(our audio files) has some inherent SEO value if hosted correctly. Is that true? And if so, how important would you think it is? Secondly, assuming that it does have value, are we losing that value by having them hosted on a sub-domain? I have read things that say sub-domains are bad, and I have read things that say that Google at least has been treating sub-domains as sub-folders, but I can't find anything definitive one way or the other. On another note, another thing I saw is that people are linking to the sound files directly in various places, and those links are going to the sub-domain, not the main domain. There aren't even pages on the sub-domain, just the files, so those links deliver a "visitor" to a page that is completely blank except for a tiny little audio player. Not sure what to do about that, but that can't be good one way or the other right? How big of a problem is this really? Is it worth me going to our IT dept. and trying to change it? It sounds like it would be a pretty big deal to change, so I'll need a few voices to back me up if that's the case.

Consolidate 150 domains to 1
Hi! Just as the questions tell we are looking at a project where we might have to consolidate 150 different domains into 1 (of course with a corresponding page on the new domain). We aim at preserving as much of the linkjuice as possible from each domain. Any advice on doing this propely? I, of course, see a risk of opening the new domain and just redirecting (301) the old domains to the specific page on the new domain but is there any right or wrong way of doing this? I might add that each domain has a more or less unique linkprofiles in terms om linking domains, number of linking domains and such. Our dear friend Cutts has some information on this topic, http://www.youtube.com/watch?v=l7M22teF3Ho but he only talks about 4 domains - which of course seem like a bit more natural occurring phenomenon. But what about 150 of them? Anyone got any advice? Is this as much of a no-go that I feel it is? Thanks! Edit: There domains are all owned by the same entitiy, share the same GWT and such.

Large Scale Domain Forwarding
I recently purchased a domain from a domainer who owns and parks many, many exact match domains in my niche. He gets a lot of type in traffic via these domains and is willing to forward them to my domain to help get my site started with traffic. We were planning on forwarding a few dozen domains at the most. I'd like to make sure I'm not raising any red flags with google for forwarding so many domains to a new site. I found this article, which says Panda made some changes with regards to what I'm trying to do here. Not sure if they guy is right though. http://domainate.wordpress.com/2011/10/20/how-google-panda-affected-domain-forwarding-and-what-to-do-about-it/

How to move website to new domain?
We have a website that has run under the same domain name for the past 10 years. We have built up a decent amount of SEO "mojo" (and traffic) over time, however, the original domain name no longer applies to the business model. A little over 1 year ago we started using a new brand name for the website and created a landing page for that domain name. Everything on that landing page links over to pages on the original domain name (to preserve the SEO value that we have built up over the years). We would like to move all (or most) of the pages/content to the new domain name. Would using 301 redirects be the safest, most effective way of doing this? I have heard of other people doing it this way, and often they will see their traffic drop for a few weeks before it eventually comes back. Anyone else had experience with this? What worked? What didn't? Thanks!

Penalty for using expired domain?
I was wondering if anyone has any experience using dropped/expired domains with old "clean" backlinks for new sites. Is there be a penalty for doing this (with good intent)? Worth a reconsideration request?
