The PR News Blog has a nice post on the difference between branding and awareness...
"Often people mistake branding with awareness. Awareness is fleeting. Like a fireplace -- there's fire as long as you're feeding it logs. Branding is the ability to leave the family room and still feel the glow of the fire within."
I also liked their advice on making sure your brand possesses the four tenets of branding: intellectual, intuitive, emotional, value-based.
A good article to keep in mind when discussing awareness and branding campaigns with clients.
