Customer opinion sites collect and present customer opinions on a variety of products and services. These sites can provide a surprisingly easy  way to build up a regular monthly income with little effort.

How do they work?
You write an opinion on a product and, if your opinion is subsequently read, you receive a payment. In addition, most of these sites operate a reward scheme for particularly valued reviews or opinions. There are often opportunities for other rewards, such as filling in gaps in product reviews.

Making the Most out of Paid Opinion Sites
The key to all of these sites is understanding the community aspect. If you read a review you can rate it for its usefulness and leave a comment with a link back to your own reviews. After a few weeks, you'll notice regular names appearing and be able to develop a rapport with these people. Building this circle of friends is useful since they will read all your reviews (and you would return the favour) which ensures a reasonable number of reads for each of your opinions.

A real bonus in this line of work is that you, because you retain ownership of the opinion you write, the same opinion can be posted to a number of sites to increase your earnings.
