1) Sleep on it test :Let your copy sit for at least a day. Don’t be surprised that you’ll feel that your letter need some works the day after. Rewrite your sales letter at least 3 times.

2) Reading aloud test : All the bumbs and rough spots jump out at you when you’re reading aloud. Better yet : have someone else read it for you. As they’re reading take a copy of the ad and make notes on it. If the reader is having trouble, you know that’s an area to edit. Remember to use short sentences.

3) Sneaky opinion test : print your letter and remove your reference, take it to people in your target market and tell them I found this on the web. If they ask "do you do this ? " " How can I get this done ?" (they want the product) it’s a good sales letter. If they say "did you write this ?" or "this is really good", your letter isn’t that good and people are simply being nice to you.
