hello i am a tech freak cum programmer, running a simple Free Tweaks and tricks blog to optime internet speed. I changed my ads colors and size between posts two days ago and yesterday i earned $4 & today I earned (from my second blog in signatures) a sum of $5.76 from some (i hope 20-30 clicks). i can't tell the right no. of clicks b/c of not naming my ads, so which ad on which blog earned what cannot be determined. is that good going or just a result of change.
