It’s a blogosphere favorite for good reason — “list” content works, in large part due to the attention-grabbing power of the headline.
What may be news to some bloggers is that the effectiveness of this type of headline and content is as old as the advertising hills. So you shouldn’t worry about it dying out anytime soon.
Any headline that lists a number of reasons, secrets, types, or ways will work because, once again, it makes a very specific promise of what’s in store for the reader. A nice quantifiable return on attention invested goes a long way toward prompting action, and as long as you deliver with quality content, you’ll have a satisfied reader.
