10 rules for writing effective ad headlines that can increase sales volume by 10x (adapted from the late, great David Ogilvy).

These rules apply equally to #PPC ads, @facebook ads and landing page headlines. A better headline can result in 10x more sales. Rule 1: Flag down your target customer in the headline. If you're selling to mothers, use the word "mothers" in your headline. Conversely, don't exclude anyone who may be a prospect for your product. If you're selling to both men and women, don't exclude men by calling out women.
