Maybe I don’t know shit, but dozens of rankings for “insignificant keywords” will never produce $50k plus per month, that is just fantasy.
Dozens of decent secondary keywords may produce 5 figures per month but in the casino biz, even secondary terms can be tough to rank well for.
If anyone is in fact getting 500 players per month from secondary terms, then they have a hell of a lot of sites and are working hard for every dime they make as the maintenance would be a killer….
