Contrary to what many think, it is not hard to create a good ad. There are many great ads that may appear very different on the surface, but ultimately all follow a simple rule: less is more.
In any advertisement, the timeframe you have to make an impression on your audience is limited to seconds. For billboard and print ads, this may be as little as 3-5 seconds; for radio and television, 30 seconds is usually standard. This limited time and space may encourage the notion that the ad or commercial must be full to the brim with information. This is misleading, and merely creates a cluttered, schizophrenic ad that becomes lost among similar amateur efforts. It is far more effective to develop a concise, coherent ad that appeals well to its audience.
