Do not try to make your headline so short that it fails to express your idea properly. It's more important to say what you want to say - even if it takes 20 words to do than make it short and fail to express your idea.
John CaplesEvery single element in an advertisement - headline, subhead, photo, and copy - must be put there not because it looks good, not because it sounds good, but because testing has shown that it works best!
