With all due respect, you’re kinda asking the wrong question, Dante and JackTen.
If you really want to put together a website that is important to the online gambling industry (like Casinomeister.com, for example) then that is one thing. If you are looking to maximize your return for the time you invest, then that’s quite another.
Personally, I try to minimize the amount of time I spend on my gambling based sites..I’m not really interested in casino gambling at all and bingo only holds a very marginal interest for me. Thus, I don’t want to spend a lot of time creating content, updating promotions or any of that stuff. I do have a stronger interest in sports (well, soccer) betting and thus am prepared to expend more effort in that direction but I only have 4 gambling based sites.
All I try to do is ensure that they bring in significantly more than I either spend on marketing or on updating/creating content etc. At the end of the day, it’s all about the revenue.
