Hi Kent,
I'm curious to find out how the offer has been working for you.
I'm the Affiliate Manager for Hostpapa and I did some research and found some stats that may help you.
Now please keep in mind that every case is different but here are the most recent averages (1 week) from our other affiliates - as of Feb 06 2008
And I rounded the numbers.
For a click to sales ratio its around 2%, and some are as high as 3%.
So you should be making 1-2 sales for 100 clicks.
Some other figures:
For a click through ratio it's at about 3%
For our Effective CPC it's around $1.50
Let me know what you think - IMO we can always make it better

Cheers,
Tim Michael
