OK…..
So I checked out your website.
1. Site looks ok however almost plain and ugly “Nothing Personal, just being honest”
2. You need more unique content.
3. You for sure need to invest some money in SEO, Buy some links etc for keywords your going for. Do not go for basic keyword searches like online casino or casino because It’s not going to help You unless You have $250,000 to spend on it 
4. More Unique Content
You will do fine if You follow these steps.
