Here I've including a step by step blueprint that you can follow.

1.Create Hope
Tons of people out there are looking for "hope" every day. People buys diet ebooks are hoping that they will be as slimming as the super models or people buy how-to-beat Google ebooks are hoping they might get their advertisement to the top rank in Google. People buys because they "hope" this decision will make them happy. So invoking HOPE is the most crucial aspect that internet marketer use to make their Website sells like crazy.

2. Sense of Urgency
The second attribute is to deliver the message of a sense of URGENCY. This is important when you try to sell to a potential customer. For example ?purchase before tonight we'll slash the price to half? or ?order now as the price is going back up by end of today?. But honestly, most of the time if you revisit the site again tomorrow, it would still say the same thing. However if your product/service is good, this will work very well as in a way this kind of speed up the decision making process for the potential prospect.

3. Appear as an Authority
Due to the overloaded scams out there, people would prefer to deal with the expert referring to the subject and trustworthy. I mean if you are the basketball player, would you listen to Michael Jordan or me?

4. Causing Fear
Create fear to your visitors by make them think that they will have more problems if they don't purchase your product/service. For example for an anti-aging product, you could show a photo of an old lady with thousands of wrinkles on the face on your site and say can this be you?!

At last, I'm sure you'll have a good result if you can combine all the above attributes into your sales letter.
