The Most Successful Ads I’ve Ever Done

Some of the most successful ads I have ever done have been newspaper ads with the headline:
Don’t buy [ product ] until you read this!!
The ad would go on to educate the reader about the value and benefit of my clients’ product. The ad would never denigrate the competition, it would simply clearly show the differences between their product and my client’s product.
It’s a simple, old, easy and effective technique.
