Hi Mancar,
For the French version of your product do you have any landing page templates?

For people complaining that PPC doesn't work:
It is all about testing. You need to test, test, test. And then when you find something that works ... test more to optimize!
I spend 50k per month plus on PPC ads for my day job, and I know all about the frustrations of not making sales as fast as I would like to. But once you get into the mind of your prospective customer and start tweaking, you will see results.
Think about this: If PPC "didn't work" (like I see so many people claiming) would businesses spend MILLIONS every year on Adwords, Bing, Facebook ads etc? Of course not! PPC is amazing if done right ... you can drive traffic so quickly and there is so much optimisation that can be done.
But PPC isn't friendly to poor quality affiliate promotions. Direct linking, or even single-page lander linking can make money. But I guarantee you'll get better results if you build up a proper niche-targeted site about Sciata (or whatever product you're promoting).
