Thanks for the question - Fotomoto doesn't actually host or power your website, so you're free to install GA on your site to track the effectiveness of your campaigns.
We do provide some visibility in to sales & stats - for more on that see this article.
I hope that helps and kind regards,
Yes, but it would be nice to be able to have either:
1) The ability to designate a landing page after successful purchase on our own site, something to confirm to the buyer that FotoMoto and MySite are connected and all is well. This landing page can then be used in Google Analytics
2) The ability to attached a tracking GA code to the shopping cart itself.
Google Analytics isn't solely for the purpose of tracking web visits, etc from a hosting stand point. It provides a wide assortment of tools to be used in tracking online merchant activities (fail shopping carts is one example).
