I would start by increasing the right padding in your content area. In FF the text is going right to the red border. Font size is kinda small. Put a space between your paragraphs (use
tags) to make it easier to follow. Make headers stand out a bit more.
These are just some things you can do on your website that might help. I would also check your traffic sources. If all your traffic is interested in sports betting then its not targeted well enough for online casinos.
BTW you have meta keywords and description in the middle of your source code. That goes up in the
area.
