The most important part of any sales letter is the headline, so you must make sure that your headline has these qualities:Does your headline talk directly to a specific group, and does it state a problem that they might be having? Your headline needs to have many different things in it to be the most effective.

Also your copy should include testimonials. Testimonials are the best way to create credibilty and trust and help you to sell your products. To get these tesimonials you are going to have to ask your customers. Ask them to let you know what specific benefits they gained from using your product. Don't forget to include their full information. The more details you can get from them the better. The best are video testimonials and there are many sites online that provide this service. All that is needed is for your customer to log in to the site and record their testimonial. They can practice with it until it is correct, so they can do it as many times as needed.

Do you have bullet points? Bullets are often the reason why someone purchases a product, this is because an effective bullet will get noticed.

What makes your offer so good - do you have a really good reason why? They will want to know exactly why you are offering them such a great offer and such a cheap price, so tell them honestly. Is it because of a new line of products just about to come out? No matter what the reason it's important to tell them.

Did you include a guarantee? Ordering your product doesn't need to be a risk, so take the risk out of their purchase and offer them a guarantee. Here is something important to remember, the bigger the guarantee the better, because it shows them that you stand behind your product.

Do you have a time limited offer? If not you should consider it as it will cause people to take action immediately rather than procrastinate and increase the risk of a lost sale.
