What goes into an advertising campaign?
A campaign has four parts: a clear objective, a defined audience, one big idea, and a media plan that delivers the idea to that audience at the right moment. Creative without the other three is just decoration.
The big idea is where most campaigns fail. Experienced teams ask the same smart questions as every competitor, get the same tasteful answers, and produce work that wins a local award and moves absolutely nothing.
We look for the idea that sounds a little dumb the first time someone says it out loud. Those are the ones that work. (John wrote about it: Dumb Questions: Where Great Marketing Campaigns Often Begin.)
