By the end of the year? I'll wait for one or two more weeks and if it doesn't go back to relatively normal levels, I'll be ready for changes.
I already replaced some AdSense units with Chitika units (most my domains approved for Gold). Surprisingly, Chitika ads are very well targeted and eCPM is good. I think I can get way better results if I move Chitika ads to prime locations and remove AdSense.
I will try improving my eBay affiliate earnings.
I'll find some direct advertisers.
