it\s not as simple as it sounds.
Yopu might have a great name that is very valuable as just a 'name' but with no traffic, so that wouldnt bring you much daily.
But on average, as to give you an idea, for the majority of names, expect .05 to .15 cents per click. My average is .10 per click.
Multiply by the number of clikcs your visitor are expected to make and you got a number daily.
There is no average % of visitors that do click, it varies from 0 up to 50%!
I guess it depends on the quality of the traffic. I have 1 name that brings in about 50 daily, and for 2 months NOT 1 single click, even though I optimized the wording (as they use google adsense).
Yet on the other hand 1 brings me good traffic with about a steady 40% PPC.
