Provide your customers with testimonials from other customers just like them.

Overcome customer reluctance by demonstrating how well your product has worked for other customers with similar problems. When using text, audio or video testimonials, a complete name and company name along with the city is most convincing.

ALWAYS offer a guarantee.

By this I mean a STRONG guarantee. Something that shows your prospects you have complete faith in your product. A good guarantee period is at least 90 days and a one-year guarantee is a true winner.

ALWAYS issue a call to action.

Tell your readers clearly and precisely what you want them to do. Do Not be timid. Tell them more than once. If you don’t, you run the risk of them not doing anything.
