A unique review is a review of a product or service that has never been done before. The advantage of doing this is that you will be the first to write about your experience and the first to review it, thereby increasing your visibility in search engines.
This will help you increase traffic to your website because people are searching for information on new products and services every day.
How can I do this?
You can start by researching similar products or services in the market and see what problems they solve, what benefits they offer, etc. Once you have identified those things then create a list of questions that should be answered by anyone who wants to purchase such products or services. Write down all those questions on paper and decide which ones need to be asked during the interview process when someone purchases such products or services from you. Then send out an email with these questions to potential customers who want answers on these topics, asking them if they would like an exclusive review from you as well as some details about their experience with the product or service (price paid, time taken for delivery etc.). If there are any specific points that need more elaboration then include them too!
I hope it helps!
