The problem is there are some services you don’t even know exist that could be much better than how you’re currently solving a problem. Think prevention vs treatment of a problem.
For a concrete example:
I learned about a dog groomer that comes to your house this way. Maybe it should have been obvious there would be some that made house calls but searching Google maps for groomers tends to return the ones with locations that you drive to.
Dog hates the car. Problem solved with a thing I didn’t know existed.
Like, the SlapChop is a good counter example I think. The commercial demos the item, makes it looks useful, uses hot sales tactics, a bunch of people think "it's just 20 bucks, and chopping stuff sucks", buy one, and now we've got a bunch of SlapChops in the landfill because in practice they're finicky and more annoying to use than just a knife.
To me, it seems like by volume commercials mostly fall into trying to convince you you want/need something that's ultimately not that useful vs inform, and the vast majority of actual useful things I've found via actively searching, or via word-of-mouth / seeing it at a friend's house.
In my personal life I pretty much never see ads and I like it that way, but thanks for giving me something to think about.
