Topic says it all, working on a site that will be for tourism. I have already started and was thinking how to monetize it the best without ads. Logical thought was offer people to book planes/trains/buses ext. and accommodation. This would be my first try in CPA and would like to get as much information before I do this to my site. Has anyone made some good income with this type of CPA? Any tips/ideas you would share? Maybe you can give me some ideas for other ways to monetize the site w/o adsense? Cheers!
