I worked for years in tech, and adjacent to marketers and sales people.
I know from direct experience that people want relevant advertisements for things that will solve a problem in their lives.
Going back to my example, I would very much appreciate an advertisement for a cigar store that will either give me a discount, introduce a new product to me, or deliver my product on my schedule.
I also make and buy mechanical toys, and I’ve had an interest in them for decades. I would really appreciate an ad that highlights a new collection of mechanical puzzles.
But instead I get badgered by Google ads for things that are nuisances and of no relevance to my life.
Instead of sharpening service for the professional barber clippers I own, because Google knows I cut my own hair, I get advertisements for Manscaped.
I steadfastly maintain there is an opportunity to advertise to people in a helpful way, but Google doesn’t do it.
