Hello everyone,
I live in Switzerland, the country of the four languages!

I am¬*building¬*my own consultancy site (Communication 2.0) and Internet Marketing) on Wordpress. ¬*I am wondering what is better for SEO:

-one wordpress site with a multiligual pluggin
-two wordpress sites with a different extension ¬*(exemple: french .fr and english.com)

Thanks for your help
