why are some clicks for financial keywords 10 cents and others $1.50?

[gdubz]

It seems like it should be a little more consistant. I have a auto loan name that gets 80-100 uniques a day and about 15 clicks a day. I earn from between $10.00 to $1.50 a day. Some days its all 10 cent clicks, some times its average .60 cent clicks. Its all U.S. traffic, so i dont see how it isnt more consistant.
Anybody know what's going on? Or where i can get a more consistant cost per click?

thanks

Are you sure the traffic is only coming from U.S.? Another reason for the inconstintant cpc could be that visitors are also clicking on "Recommended Links", which changes the keyword for the visitor and the cpc changes as well.

I parked it at namedrive for a day and it showed that it was 95 percent u.s.
you could be right about the recommended links though
