Hello, I have set up a campaign a few days back for a CPA offer by offering a max 0.25$ CPC. It has now run for 2 days and I have a CTR of almost 5%. I have been paying about 0.2$ per click overall and $10 CPM. I would like to, now, switch it to CPM to pay even less per click. How much should I set the max CPM now? 3,5,7$? Will I still get impressions at such a low rate? How does this moving to CPM from CPC now that you have determined your CTR go exactly in your opinions? Any input would be appreciated! Thanks!
