I'm making my old website multi-language. I'm designing it from scratch I was wondering which one is better seo wise. using different subdomains for each language or using subfolders:
http://www.example.com/en-us
or
http://en-us.example.com
Programming for subdomains is much easier than sub folders in my case but that's not much of an importance for me.
My Research:
I have read many many articles about it and some say there is absolutely no difference SEO wise, some say subdomains are much better because linking subdomains together generates more pagerank and you have separate indexing for each language and some say that subfolders are better. I have just got confused.
I would like to use some advice from webmasters that have experienced and tested both. I think real-time results are more valuable than reasoning, as there are good reasons for each of them but deciding without knowing which factor is important won't help much.
