CPM ads are coming. What to do?

[arikgub]

Recently I've been somewhat smart-priced and my average eCPM fell down to $5-6 level. My average CTR is firmly around 3%. My site is not MFA, the ads are not obtrusive and in my understanding the CTR of 3% is healthy. But what about eCPM, is it considered low?

Today I noticed that CPM ads started showing on my website. Is eCPM of $5 low enough for CPM ads to be more profitable than CPC?

Should I opt-out of CPM ads or let Google decide what the most profitable ads are?

Hello there. How does one tell if they have CPM ads?

Thanks for the help.

you will see zero clicks yet more than zero earnings for some pages/channels
