hello stackers!
Hopefully those more experienced would be willing to give a hand here since I'm only asking for a general strategy here, not asking anyone to share any detailed "top secret"...
i want to start building a small database of swipe files for landers and ads. Just for example 10 categories for landers and 10 categories for ads, with each category representing a completely different layout/design.
but the problem is where and how do i get started? should i take traffic sources into consideration? e.g. should i build one database for mobile, one for ppv etc etc or maybe it doesn't matter and i can just put everything in one database?
and regarding the actual approach, would you just keep visiting big-volume sites and download anything that might interest you? or any systematic approach? i don't even know where to start! 
any help please? thanks a lot!
