Hi Jane,
Both Stephen’s and Trevor’s headlines are great readership sells. I like them both.
I do think you can strengthen your “missing ingredient of success” strategy by tying a specific example into the headline, or deck copy. For instance,
One Simple Idea Quadruples London Lawyer’s
Sales-Revenue in just 3 months!
“I knew I was losing sales – but never imagined it was so many! If only I’d been doing [named below] years ago – I’d be hundreds of thousands of pounds richer!”
– John D. Litigator, London
Obviously, this approach only works IF you have a particularly strong testimonial/case study.
Technical considerations: Conditioning terms like “could”, “should”, “may” all weaken headlines. These “conditioners” have their place in copy – to soften potential negatives for instance – but I feel
should be avoided in headlines.
Re: Question Headlines: A yes/no question allows the prospect to say “no” and stop reading. Because the headline’s primary purpose is to sell the reader on reading the ad, I tend to avoid them.
You’ll notice I’m sure, Stephen’s classic swipe is NOT a yes/no question. Rather it is a “pointing” question. It works so well because readers are drawn into the copy to see what “this mistake” is. It doesn’t matter if they are making it or not – they’ll want to see what you’re referring to -- even if it’s only for the satisfaction of knowing they are not making the mistake.
Hope that’s in some way helpful.
Cheers!
John
