Hey,
All right here it comes.
– the top logo with the aces is too big. It steals the focus and it wastes your advertising space. Also on mobile devices it will take up everything above the fold which isn’t good at all.
– that twitter widget is taking a key spot, where you would want a top 10 list of casino brands or perhaps another advertisement.
– lack of call to action words. For example I have opened the bet365 mobile casino review and there’s not a single link with anchor text in it. In fact all there is a picture with a link, that me as a visitor may or may not see that it has a link. People will most likely look for a button that tells me to register/visit/sign up or a similar link.
– Good articles, but perhaps for conversion purposes you might want recommend a casino where someone can enjoy those games, after they have read the rules and etc.
– that 468×60 banner on some of the articles is flash and stays on top of your menus, therefore making the navigation quite difficult.
That’s just some of the things for a start. Fix those and you will see a good % of visitor retention and time on site.
