What's the list is based on?
Who paid you the most?
I mean lol, you should at-least mention what's the whole rating is based on, have you tried those websites by yourself?
The fact that you are doing a review is nice, but I think that if you want people to rely on this information and to actually put their money into those sites, you should atleast provide them with some details about the authenticity of the sites.
These sites are located in the ranking by popularity, by data Alexa Rank (
https://www.alexa.com). Alexa Rank is fairly accurate and makes it possible to evaluate the popularity of sites according to their places in the world's Internet traffic. In other words: the more that one or another site is more visited, and therefore more popular among the players themselves, the higher it is in the ranking in relation to its competitors.
Here is an example for the 1st site:
