Hi,
Welcome to the forum. Most webmasters here do poker and casinos, so it will be interesting to hear from someone who has experience with sportsbooks. You’ll also find that a lot of webmasters dont do bingo due to poor returns. From my experience you can earn more promoting freebies and just about anything else than you can with bingo. My bingo site is earning me on average $0.01 a click that I send to the merchant.
