What's the best way to monetize French and Swiss traffic?

[Datalife]

I got a domain that gets French and Swiss traffic. What's the best way to monetize them? Should I set up a French language website or an English one (with option for French translation)? Anyone with experiences?

Thanks for any ideas

You need to research out the potential keywords in google.fr search results and optimize them for better search results, also submission of the website in french directories could help you in getting french traffic.
