Long sales copy can be very effective and certainly has its place. Briefly outline your offer near the beginning, then come back to it in more detail later on in the copy. Break your copy into short sections. Professional writers often keep their paragraphs to two or three sentences. Most readers are in a big hurry.
Long paragraphs look intimidating and hard to read.
For instance, use a headline and subheadings to proclaim your most important points. Detail your product or service's features with bullets, linking each feature with the benefit it will give a customer. You can also use Bold and Underline to create emphasis. Most people read in a big hurry and don't take time to put all the emphasis in the right places. They may skip over the most exciting, crucial part of your offer.
