Yesterday was looking kinda grim but I had a late night surprisingly large click dump.
I know what's causing my sawtooths (such as they are - sawteeth?) It's mobile. My mobile traffic has an entirely different dynamic than my desktop traffic, and on my biggest day of the year so far (last Saturday) it actually crossed over to 53.9% of my traffic, making it the majority.
My mobile traffic has a much smaller CTR and a much higher EPC than desktop.
My mobile clicks tend to happen much more at night rather than during the day.
If the mobile clicks are down, my day ain't great.
I'm pretty sure that some amount of my mobile traffic is not *in addition to* my regular traffic, but instead of. And that makes a difference.
That said, I'm still way up over last year, mainly because traffic as a whole is way up, and EPCs are way up too.
It's certainly a roller coaster we ride.
