Benchmark Data Vanishing[ Edited ]
November 2016 - last edited November 2016
I noticed that a lot of benchmark data seems to be missing, starting in October. There is a sharp decline in the number of web properties in many of the Shopping sub-categories, and in the case of the "Custom and Personalized Items" categories for sites larger than 100 sessions/day, no data at all beyond the 7th.
Was there a change in Google regarding how website data is collected or displayed? Did a lot of users suddenly switch benchmarking off? I noticed that even in generic categories there is a huge drop from September to October. In "Shopping" specifically, 100-499 sized properties decreased to the tune of 44,000 fewer from Sept-Oct.
