Google AdWords conversion tracking
I want to sell my book (print and e-book) with Lulu by advertising it with AdWords (and also probably Facebook).
Sadly, as it seems, Lulu does not provide AdWords conversion tracking.
Does it make sense to consider all clicks from my landing page which lead to Lulu as sales? Or contrary are there many users which click the links with text like "Purchase for $10" but do not purchase?
