I've been investigating a usage spike in our Google Analytics system and have just noticed a change in the historical data.
Last week our the number of users on our site for March 23, 2017 was reported at 13,335. Today that number is 13,985. How can this happen? How can 630 users come to our site for a past day? Additionally the data from last week also dropped 177 users (26,648 vs. 26,825)
Here are screenshots of the analytics reporting (newest first):
I'm currently investigating how our user usage is increasing but our server logs show no drastic change (aside from Google bots, 2017 google bot count 2k, 2018 bot count 100k (both numbers for the day in question)). The Google bot count make me think Google is altering the way they count themselves.
