Here’s some great info from Perry Belcher back on March 8, 2011

A few years ago I read an article by David Frey called the 12 step foolproof sales letter formula. This formula has literally made me millions of dollars over the last few years.  Many thanks go to David, a brilliant marketer from San Antonio Texas.  Over the past few years I’ve added a few points today this formula, and I like to share this with you now.
I kind of feel like I’m painting a mustache on the Mona Lisa by doing this, everybody asked how you write sales letters, and video sales letter so well. This is the exact formula to follow.

Here goes.

21 part sales letter formula
1. Call out to your audience
2. Get their attention
3. Backup the big promise headline with an quick explanation (SUB)
4. Identify the problem
5. Provide the solution
6. Show pain of and cost of development
7. Explain ease-of-use
8. Show speed to results
9. Future cast
10. Show your credentials
11. Detail the benefits
12. Get social proof
13. Make your offer
14. Add bonuses
15. Build up your value
16. Reveal your price (pop by button)
17. Inject scarcity (if any)
18. Give guarantee
19. Call to action
20. Give a warning
21. Close with a reminder

I also added my part copy test that I asked myself when I finished any new sales piece. You really should do this the day after you finish your sales letter or video sales letter, after you have had a chance to read or reread it out loud.

By the way that one tip is really important. You should always read every completed sales piece you ever write including e-mails out loud preferably to another human being. It will probably improve your copy at least 100%

Eight-part copy test
1. Did you grab your readers by the throat your readers with your headline?
2. Did you clearly explain that you understand the problem?
3. Did you show them so much proof that they can’t possibly doubt what you had to say?
4. Did you show features and benefits to your offer that included the word so in each line?
5. Did you ensure your prospects that your product will be very very easy to use?
6. Did you ensure to your prospects that your product would work very quickly to solve the problem?
7. Did you clearly explain the pain of the experience by not accepting your offer?
8. Did you demonstrate incredible value in your offer so much so that your prospect would feel stupid by not buying your product?
