i think it's safe to say that the incentives are not exactly aligned.

if i was google, i would make sure that the ctr was as high as possible while the conversion rate was just enough to be worth it.

there are a lot of fine-grained controls missing from the adwords backend which waste money. for example, you cannot segment iphones from android, or forcibly exclude ie11 because you have chosen not to support it any more and the site falls apart on it. you cannot prevent ads from showing to visitors who've already come and bounced. they keep expanding how much "modified broad" sucks in by making the matching looser - with little notice. and that's just the tip of the iceberg.

lots of things that can easily save you money do not exist in their backend. imo these are not oversights but are left out intentionally.

Do you have any recommended reading for things you can do to easily save you money before spending your first cent on ads?

ok, i guess there is a way to target to specific mobile devices:
