Use Numbers.
Numbers help to quantify what you're talking about. "Getting a Better Body"
is a fine headline, but "Getting a Better Body in 2 Weeks" is better, and "10
Steps to Get a Better Body in 2 Weeks" is better still. With numbers,
particularly those 10 and below, readers feel like they know what they're
getting into. An article on weight loss is still an article, and today's Internet
reader is fickle and wants information in a hurry. 10 tips, on the other hand,
sounds easy to scale and simple, and even the most-flighty reader can stick
around for a list of 10 items. Second, adding the "in 2 weeks" to the end
amplifies your claim and helps you stand out in a field of other articles about
similar subjects.
