It just makes so much sense even though it seems so basic - change your format to suit your audience! Good psychology, of course, but it had never really occurred to me to work in that way until I read about all that psycho-blending stuff. I've started using it with some of my other projects and it REALLY has made a difference. (a lot more, as far as I can tell, than just blending ads in the usual way). Has anyone else looked into it? Does it work for you?
I worked at an ad agency for years - we ALWAYS made ads to 'suit' our audiences - the right look, colors - even the 'right' kind of copy...
