i guess bruh. i've done some facebook ads + dropshipping before. gonna just do the standard single interest ad groups, so if quiz is about cars then 1 adset with interest toyota, next adset honda, etc
as for the rest of the settings: ad budget campaign, optimize for landing page views, traffic objective, english(all), automatic placements, start with lowest cost bidding then maaaaybe transition to bid caps
will use funny/meme gifs as the creative, ad text saying what my quiz is about, a compelling headline, and i guess that's it
not sure what else could do to get those low CPCs. is this similar to your set up?
