Was there a new algorithm? Sudden jump in sessions/visits even in previous month

I used to record the statistics per month manually by copy-paste from GA to my Excel. The statistics have always been in hundreds. Starting March, I was busy and stopped, thinking GA would remember it anyway. Just now, I went back to retro retrieve the numbers to be compared on my Excel. It shows a huge jump in Users, New Users, Search terms, etc.

 

Jan: 217

Feb: 325

Mar: 3335

Apr: 2865

etc

 

Good thing? I then went to check Feb numbers, it is now 3332. Not good.

My Excel's number of "August 2016" is 602, now GA is saying it's 2857!

 

I didn't change the filter, or segment, or dashboard, why is the number being calculated by GA different now?

Hi LL!

Thanks for sharing this out.

This rarely happened, though it never happen to me in my 5 years handling GA. Did you double check your date timeline?

Hi Jarric,

 

So this has happened before?

 

I tried to investigate what is wrong, don't know what's wrong. What I know now is:

- only one of my property is affected, that property is the main property of a domain that has four properties, the other domains are not affected as far as I know

- the last time I touched tag manager was 8 months ago, but if it was caused by tag manager, my other properties should be affected as well

- not caused by GA's dashboard, unlikely in the first place, but I remade it anyway. Import another dashboard from another property, same result

- Anti-spam filters, view segment: I redo/updated those as well
