Remember this routine from George Carlin? He mentions nearly every hucksterism known to mankind. My colleague, Tom Wanek, has taken all of Carlin's phrases plus hundreds more and created a cool and free tool that allows you to paste in your ad copy to see how you rate. (Hint: the more your ads sound like ads, the more they blend into the background of the thousands of other ads your audience is subjected to each day.)
The key is to stand out by NOT sounding like every other ad. It's not easy. Here the link to the Ad-Speak Calculator.
