Seth Godin has written a great post asking what you would sell to a prospect if you had one hour to do it.
My answer is (ideally) not one thing. I would want to spend that hour focused on building a relationship. If I were forced to answer this question by providing one thing, I would say selling myself as I think all sales are predicated on a person liking and trusting you.
Business Week: Jon's article on Advertising in 07' is on point. The three keys to approaching it are listed below but the article is great...Enjoy!
ONE: BIG MARKETERS HAVE TO RELAX about getting weird. Video ads that get the biggest online bang are those that elicit a simple three-word reaction: "What the hell?" I do not posit this approach as the be-all and end-all of Web creativity.
TWO: MARKETERS MUST BE PUT AT EASE in places where consumers run a little more free than they do in, say, a car showroom. Volvo has sponsored a kind of best-of feature called "What's Your Story?" on Microsoft's (MSFT )x MSN Spaces blog network since 2005.
THREE: MORE AND BETTER TARGETING. A marketer's fantasy about a site like MySpace isn't reaching its massive audience but identifying and targeting a few thousand highly influential or relevant members.
Seth Godin post's "The T-shirt Rule" suggesting you would buy it if you had an remarkable experience. The T-shirt, the snow-globe or the hat! It doesn't really matter if you loved the experience you want something to remember it by.
I would argue that it really depends on the price of the shirt. hehe
