To paraphrase the old saying:
People believe half of what they hear (or read) - and almost all of what they see. The same is true of what they remember.
My daughter just gave a presentation about "Helicopter Parents." These are parents who hover over their children, providing unnecessary assistance, even to the point of attending a job interview with them. (You wouldn't believe the stories...)
Her points were excellent - but the most memorable parts of the presentation were the visuals she found. They included:
• A smiling baby - duct-taped to a wall- along with her stuffed animal.
• Two young children peering out of a large pet carrier.
The same is obviously true of advertising and direct marketing. Great visuals can add a great deal to your effort - and make your work stand out and be remembered.
