What it does
A good headline gets the reader in. Then the copy has three jobs: make the want sharper, make the claims believable, and show why the promise could be true. Most copy does the first badly and skips the other two. This workflow follows the order set out in a summary of Eugene Schwartz's Breakthrough Advertising. First it builds the want from several sides, using only moves your facts can back. Then it scores your claims for how readily a doubtful reader accepts them and rebuilds the order as a ladder of small steps. Next it adds a short cause-and-effect passage that explains how the product gets its result. Last it pairs each claim with proof and flags the ones that outrun it. The source is a third-party summary, so treat its detail as second-hand.
