Copyblogger is an expert when it comes to using the power of making list posts. He has done wonders with them, and so have many other bloggers, all thanks to the fact that none of us have any attention span.
Simply put, lists work because they conform to the idea of “Left-Brain Marketing”. Everyone has two sides of the brain, and each part controls a specific way of thinking. The left brain is analytical, and prefers a step-by-step approach (i.e. lists) while the right brain prefers to see the big picture first and then deal with the details later.
Television commercials take the right brain approach with highly-produced images and expensive repetition. On the other hand, the left brain list format has been a successful approach for many decades with direct marketers, magazine publishers, late-night comedians and more recently with Internet content producers and social media marketers.
Many social media users want to know exactly what they’re in for, and the list format caters specifically to that need. It lets them know up front in the headline what to expect and what the time commitment will be.
If you want to gain some attention to your blog, set up a few list posts about pretty much anything, and you will most likely see some decent return. I, for one, hate the longer 101 items lists, but give me a dozen points on being more productive, and I will probably read it.
