thats probably the worse CTR i have ever seen. you can certainly do better but we need to see your site to advice
Thats a very poor CTR. I hate anything less than 1% and so should you. At that rate 1 affiliate sale of a moderately priced product every 2 years, could earn you more. Plus you get to have the link open in a new window that way so your site stays live with your visitor. Not knocking adsense though, I love it.
VERY low CTR. But if you improve it you might earn some bucks because that click payed nicely, $079 must be considered really good!
