Yes. Up for me, over the last few months. After the last attack on MFA sites, I think that I somehow "graduated" into a higher "perceived quality" bracket, which resulted in higher ad payout. My secret? I graphed my EPC vs. CPM, and I found a direct correlation. Poorly performing pages get AdSense removed, and something else added. Do not allow poorly performing pages to drag you down. Strive to improve your overall CTR, and your overall EPC will go up automatically. At least, that has been my experience. Give it a try.
