Hi there,
My 1st thought are it’s very light on content so a lot of blank space on the home page. I like basic sites but perhaps adding some more content and trying to sell each promotion your putting there would be a good start.
It may also be a good idea to have a text link to “Claim The Bonus” and one to “read the review” the review is where you need a more indepth write up about each casino again with the purpose of selling it to the reader before showing them where to go to get it.
p.s do a spell check
