Never stop testing, and your advertising will never stop improving. Testing was used in advertising decades ago. The internet has made testing so easy that every online marketer can use it to improve advertising results. Google content experiment is a free tool for you to do split testing.
David OgilvyIt strikes me as bad manners for a magazine to accept one of my advertisements and then attack it editorially - like inviting a man to dinner then spitting in his eye.
David OgilvyYou aren't advertising to a standing army; you are advertising to a moving parade. Three million consumers get married every year.

An advertisement is just like a radar sweep, constantly hunting new prospects as they come into the market. Get a good radar and keep it sweeping.
