Yesterday 12 was slow but got better right before midnight.
Today looks slow, slower.
The only clicks we notice are the ones in the Adsense report, no metrics on lost/invalid clicks or whatever, but there is a growing ad blindness. I'm running an experiment and it's confirming this, so let's play with ad positions and variations.
Anyway ADSENSE is way slow. Been running speed tests and using G Insight and guess what, the part it tells me to be the slower one is G Adsense scripts. Really slow.
