We live in an over-communicated society.
Heck, when I began in advertising and marketing, adding an outbound phone call to a direct mail campaign was considered "Integrated Marketing."
The fact is, we are exposed to thousands upon thousands of media impressions each and every day. As such, as consumers, we CRAVE simplicity. If you can simply explain what you are selling (which, by the way, is what advertising and marketing is), and how your product/service will benefit me, then wrap in a compelling reason -- the correct messaging and/or offer, I will likely take the next step in your sales process. But please make sure to explain to me what you want me to do -- call, respond to the email, visit the website, like us, etc...
Precise copy is the key, but we also must consider how we can graphically simplify our message so it is easier to digest and get the point across immediately. Here is an example of what I mean: http://www.a2591.com/2011/03/more-minimalist-effect-in-maximalist.html
Most of these everyday products are, perhaps, better served today as stripped-down versions.
That's why the combination of video and the internet/social media is so hot right now. A great video story teller creates the impression we want, quickly and memorably. We don't mind watching the quick story. However, don't confuse this with just entertainment. Typically, entertaining does not translate into more sales.
So have you simplified your advertising and marketing? Have you reaped the benefits?
