At the scale of a McDonalds ad campaign that seems easy to measure: go to the nearest Target parking lot and ask as many people as you can two questions: "are you vegetarian" and "did you see {description of ad here}". Then compare how which percentage of vegetarians saw the ad compared to the percentage of non-vegetarians saw the ad. There are even companies specialized in market research that will do this in a more representative and statistically rigorous way

Google has no incentive to do so. McDonalds does, but its somewhat costly to scale against ALL the ads they push.

		For pay-per-click ads, if the vegetarians won't click, that's a lost opportunity to show a veggieburger ad Google would have made money from. Google has a lot of incentive to optimize this, and it's a lot of why they (and Meta) spent so much money on AI research that eventually brought us modern AI.
