The ad I most frequently get on YouTube - we’re talking three times per video, every other video - is for a shingles vaccine targeted at adults over 60.
No amount of spaced repetition is going to make me, an adult decades under the age of 60, talk to my doctor about that shingles vaccine. This cannot possibly be a truly cost-efficient ad platform.
