Translation of your sites to foreign languages is definitely a great way of increasing traffic and revenue streams so long as you are offering a method for this international traffic to join your site.

We actually started the industries first adult translation company back when nobody was actually thinking about their international traffic and have worked for several of the industries top names including AEBN, Platinum Bucks, ARS, etc if you are serious about translating your sites I would be more than happy to discuss this with you further
