Hi all! Im starting a community website and was thinking how to estimate income, roughly. 1) Facebook revenue per registered user - estimate per estimate, I guess. (i know I probably cant get the same amount on site spend as FB - but still...) 2) monthly page impressions = the google adsense income X amount would generate. I know this is very roughly estimated, but id still like to put my start up costs into perspective. Any other ideas on how to estimate this? And any ideas on the numbers?? /E
