You might want to post a links page so webmasters can trade links with you…that will get your site listed in the search engines much faster.
Though I am not a veteran casino affiliate webmaster, I would also suggest decreasing the size of your site explanation and page title on your homepage, and putting a casino banner of some kind in its place.
People generally decide whether or not to surf a website within 4-7 seconds of viewing the homepage, so I would hit them with a banner or two to get their attention.
