Do you seriously think that ? My experience is so dissociated that I think it unbelievable. I don't remember ever seeing an ad for a small business on the web, even less discovered one through them.
I discovered most small businesses that I use through word of month, seeing them while traveling or active search through google or google maps. The ones that I may have discovered through ad where through local physical add such as any box fliers or fliers/posters in other local businesses.
in order for to see small business ads you really have to have your browser fully exposed in order to be targeted - small business are local and feeding ads for a massage parlour in sam diego to me 3,000 miles away is not a good allocation of marketing money. I am 50 and have never, not once discovered a small business through an online ad
