Any Shopify App Developers That Have Found Success with PPC in the Marketplace?

Hey guys!

Pretty much what the title says. Working on growing a newish Shopify App right now and am wondering best way to approach PPC (I see it as a means of getting initial traction, which then can be used to generate reviews, which will then help to move us up the ranking organically).

Not a PPC expert though and feel a bit overwhelmed in tackling/putting $ behind campaigns. Wondering if anyone here has had success with it or has any resources they could share for campaign setup/management/optimization?

Thanks so much!
