Problem Agitation Solution
This formula is great for pain aware prospects. It works so well because people want to avoid pain at all costs.
You start by describing the problem. You name the pain and make it tangible. Then you agitate that problem by highlighting the emotions that go with the problem and reminding them of how bad their situation is. Finally, you present the solution, your product.
Even though PAS has no action at the end, you should always have one.
Variations of this formula are:
PADS (Problem Agitation Discredit (where you discredit other solutions) Solution)
PASO (Problem Agitation Solution Outcome)
PASOP (Problem Agitation Solution Outcome Problem). It works especially well when writing email sequences.
