The reason why I find this and this (and this) worth of my attention (and money), while I find this, this, and this (and this too) trite and unattractive, is not that the former are good and the latter are bad.
It’s that the former target a specific audience to which I apparently belong.
I don’t believe in good and bad marketing, but I do believe in effective and non-effective marketing. Know who you are selling to, know what you are selling, and make the match.
All the rest is non-effective.
