Mine is just less than a month, and I have 4 ad units and I'm making atleast 100K a day from that 4 ad spaces. It's very nice compare to a-ads which I only got 10K sato per ad unit a day.
Very nice to hear that thing,I have 5 ads and getting 100k+ per slot a total of 500k satoshies per day with my site.
you must be getting atleast 5k unique visitors daily to get that amount. today i got 2.8K hits around 200K sats all in all..
