As you all know I joined NB a week ago and since then I've made a few small changes to my AdSense based on what I've read here. Those changes are: Added a link list, added AdSense to my sidebar, added the Break out of Frame plugin, and changed link colours.
In five days I've doubled my AdSense income however looking at the AdSense reports it seems my CTR and eCPM have halved. Clicks haven't doubled yet earnings have and I am really confused. Why has this happened? In particular I would like to ask if anyone else has ever noticed increased earnings and lower CTR, is this normal?
