On average, five times as many people read the headline as read the body copy. When you have written your headline, you have spent eighty cents out of your dollar.
—David Ogilvy
In an ad, the headline determines everything.
It is why some copywriters are known to spend 50% of their time on just the headline.
Producing an attention-grabbing headline is perhaps the most essential part of writing copy. It’s also fun to create one.
The same concept applies to magazines, blogs, business articles, book chapters, and so on: The title is where your focus should be. You should begin and end every piece with the question: “Would this make me want to read on?”
If not, don't publish until you've got an attention-grabbing headline. Concentrate on this, and you'll get more readers, more stories, and of course, lots of love.4
