all money is good right? but earnings will really depend on your niche...if only i had an interest in a high paying niche..with enough traffic, you could see some good earnings at 50c a click...
i income a relatively good amount per click from square ad unit, avg 0.25 and sometimes more then $1 per click but always very low from link unit and got only $1.53 from 27 clicks. so i removed link unit today from my site
50 cents per click is very good.. hope I got such a good CPC.. I get only around 2-3 cents per click on an average for all my sites
