One of the main aims of an effective product review is to give the prospects an inside view of the product and explain how and if it delivers on its promises. But perhaps more than anything else, people are looking for a clear explanation of what the product does and has to offer. Your conversion rates will reflect the amount of work and preparation you have done before you ever begin writing; so take that to heart.
What you will be doing with your product review is preselling to your market, and that does not mean you are doing any kind of hard selling. It would be very helpful to read about how to presell in your copy, and that is really part of the function of a review. The majority of reviews we see only talk about the good things and rarely about anything negative, and that detracts from the objective nature. Those are just several basic yet powerful aspects of reviews you should always have.
An effective way to write a product review is to take your prospect from the problem to the solution there and then. The only time you can get your self in a bind with this approach is if you fail to adequately substantiate anything you claim. What you will also be doing is giving the reader something to think about in a new way, and then they will read that the product you are reviewing can solve it. There will be other products that will provide a solution to the problem, and so you have to find out why your product is unique, if it is.
There is definitely a process involved with putting a high quality review together, and that is something you have to seek out and learn. We have not seen any direct info products about writing product reviews, but we have seen articles on the process.
