I'm currently designing a picture/file upload website and was wondering what the best means of income would be... CPM or PPC? thanks for any insight!
Methods other than PPC seem to be either a good deal (from the customer perspective) one month and too much another. If you avoid click fraud and make sure that traffic that is clicking is quality you can charge a premium for PPC. -SS
Why not try running both at the same time? Based on my own experiences and others though, the click-through rate on upload sites are quite low. Try experimenting yourself, though, as that's the only real way to find the best option.
