You should.

What’s a peek-a-boo headline? Let’s brush up on what peek-a-boo is, first. You, no doubt, know the game of entertaining a baby by covering your face and (in a really high-pitched, silly voice) saying “Peek…peek…peek-a-boo!” and then revealing your face on the word “boo.”

Think about what happens next: What baby doesn’t stop what he or she is doing (yes, including the one wailing in the seat in front of you on the plane), stare, laugh, giggle, and then–this is important–looks for more.

That’s what a peek-a-boo headline does to a reader. The headline stops the reader in his or her tracks. It startles the reader, in a good way. The reader then looks for “more” by reading what follows next (e.g. the blog post, the ad, the email, etc.).

My post from the other day–Apples, Peaches & George Clooney Naked–is one example. And every time I work on copy, that’s my goal: to create a peek-a-boo headline.

Of course, what follows AFTER the headline is almost as important. I say “almost,” only because you could have the most brilliant body copy on the planet, but if that headline doesn’t get the reader craving what comes next, then it won’t matter.
