Yes, I know that highly targeted searched are much more interesting. But I do maintain, search engine traffic in this sector is very low in term of quantities. 
I have other sites in other sectors and it is relatively “easy” (when you are an experienced webmaster and constantly work on your sites) to score 500-1000 unique visitors a day from Google. I am very far from this with my online gambling sites.
And lots who quit the business… Too much online casinos increases the cost per player and lower the lifetime value of a player.
Yes, very good remark. It’s one of the most competitive.
And one question I always think about… Think when USA *will* legalize the industry… What will happen when major Las Vegas brands such as Caesars etc… will enter the market? The brand awareness can be a powerful key driver, and players will land to gaming sites without SEs AND affiliates…
I am sure the future holds lots of market consolidation such as what we are seeing with Belle Rock and Fortune Lounge. That’s the only way most single online casinos will survive. We will see new groups created from companies merging.
But we still don’t have the answer: Where are the billions?
