Every good Creative Director should know a little something about advertising theory, "How do these ads work, anyway?"

AdCracker does not claim to have "The Answer." What we do know is that there are two basic elements to consider:

1) The audience.
And that can include personalities as wide ranging as Mr. Ni Ching, a mechanical engineer in Zuhai, China, to Mark Cuban, co-owner of the Palms Hotel in Las Vegas and the Dallas Mavericks NBA team.

Mr. Ni Ching skeptically scrutinizes even the smallest purchase. Mr. Cuban sat down and ordered a multi-million dollar business jet with a couple of clicks on the Internet. One way to understand how people approach purchase decisions is > involvement theory.

2) The communication.
That's the stuff you create.

And when the time comes to put pencil to paper, fingers to keyboard - to actually create your campaign or ad - it can be helpful to consider, "OK, what's the primary reaction I want from the target audience?"

You won't need to do this with every ad. But for new clients, new campaigns, or new ways of thinking, it can be clever to go back to basics.

What you will discover is that there are three primary responses your ads can trigger. Three basic things an advertising campaign can get people to do:

> To feel, to experience an emotion

> To think, to understand, perhaps remember

> Take action, do something

Generally speaking,

- Getting people to think and feel certain things about a company, its products and services, that’s the goal of branding, of brand-building.

The ultimate objective, of course, is to influence purchase behavior. But to do so by first getting viewers to like the product or understand the service or feel a relationship with the company.

- Getting people to do something, and do it soon - to clip and mail a coupon, click on a Web site, pick up the phone and place an order - that’s what direct marketing and direct response advertising are about.

In real life, of course, it’s not that simple. When someone sees an ad, they can react in a variety of ways, most commonly with indifference.

And if they do respond at all, then thinking, feeling, and acting can blend together in different ways with different people. The human mind is infinitely complex.

But this is not a course in social psychology.

Simply put, marketing communications focus on three primary reactions. So it can help to understand how you can make people think, feel and act.

Notes:

Truth Be Told: There is no scientific evidence supporting "subliminal persuasion," the notion that stimuli below the threshold of conscious awareness can influence behavior.

And when you look at the spectrum of forces that do influence purchase behavior - from genetics to parents and peers - you'll find advertising way down at the weak end of that spectrum.
