Hi... Last day I got $0.03/click and someday I got $1.35/click from adsense. Question is: Are there difirent income betwen pay keyword and free keyword? How about you...?
I'm new to the whole Google Adsense scene myself, but if I had to guess they would have different results yes, but really don't know for sure as I am still learning as I go myself.
Free keywords will always pay lower than keywords that have value. It's quite simple really: advertisers that are actually selling something can afford to bid higher for those keywords. Cryo.
