I’m really not concerned about the car I don’t have, the quality of my floor mop, or the latest prescription pharmaceutical that my primary care doctor is too stupid to even spell.
I really feel for the small companies. But outside extremely industry specific mediums, they just can’t afford to advertise much. They have to be known from reputation and search engine results.
So, while I see the point you are trying to make, by volume, the bulk of advertising is utter crap.
My feed on social apps and youtube is very frequently filled with small businesses near me.
