I have a few websites that are getting regular traffic. I'd like to monetize them by selling ad space but I have no idea how much to charge! Site 1 in the last month: 2,925 unique visitors. bounce rate of less than 1%. avg time spent 1:51. Site 2 in the last month: 949 unique visitors. bounce rate 75%. avg time spent 1:00. Site 3 in the last month: 389 unique visitors. bounce rate less than 1%. avg time spent 1:04. Any suggestions? In general how do you decide what a space is worth? Is is only based on traffic or should bounce rate be considered too? I don't have any ads up at the moment so I'm open to any size or space. thanks!
