One site two languages - what to do with urls?

[J_Sinclair]

Hi,

We are working with a client who has a Spanish site which is in English and Spanish, what is the best url structure to go for?

www.domain.es and en.domain.es

or www.domain.es and www.domain.es/en

or none of the above?

Personally I use the folder structure ie. www.domain.es and www.domain.es/en.

I would agree with Dean just to explain that the reason www.domain.es/en is better than en.domain.es is because the /en keeps the authority in your site rather than separating to a sub domain which sort of helps you a bit.
