I am currently update my site which selling products mainly in US.
But we have some sub-domain which I have set up for the different currency.
after a few months running, I have found google hard to found the sub domain link, yahoo always showing the wrong link which always show my sub domain link, and MSN seems ok. As yahoo is a biggest concerns, I feel I may doing the things in a wrong way.
Now, I would like to change everything back to main domain. But I don’t want to showing the duplicate pages to violate the SE’s rules.
So there are some options
(I like this one, but I am not sure if SE’s consider this way may duplicate the same content, and when people search like “Porduct1”, which link will be rank at top ?)
(this way, may increase the number of page on SE’s, but the first one may ranking high)
(no change on the url, will redirect when they click on the different currency)
Just keep the sub-domain as the way it was, but may doing something to transfer the weight to main domain product page.
I am really appreciate anyone could share your experience.
Many thanks in advance.
