adwords is not a forgiving medium, anyone who says you can get into adwords right away making money after reading adwords for beginniners, intermediate or advanced with super secret technicques either have super unique experiences or are just flat out lying.

white hat adwords is difficult, i'm sure no one will even dare say adwords is easy find 10c keyword copy ad and have money roll in, and try to back that up.

if your going to do white hat adwords, there really is no advice other than to know the adwords system, then know how to optimize it, then after that, a whole new section on seeing what convert and what doesn't and then finding the right "thing" to advertise.

you can make just as much money sending traffic to a website that has no physical products whatsoever, just as you can send ppl to a specific blue purple i*pod or something.

really imo adwords is trial by fire and trial by error, the more money you loose the better you'll get cuz you'll either try your damn hardest to make it work or just give up. i would actually suggest(if you really want to get into adwords) read more and keep on optimizing.
