Active Users report numbers do not add up
I'd need help understanding how does the Active Users report in Audience works. In the specific I have 2 questions:
- Are the numbers of visitors counted unique or include returning visitors also?
- Also I do not understand how 7, 14, 30 days active users are counted because my figures don't add up. According the image I uploaded GA tells me that in the last 7 days I had 53747 visitors so i started to count them to see if it is right and it isn't (probabily I am doing some miscalculations):
Jan 31 = 8923 visitors
Jan 30 = 7991
Jan 29 = 8182
Jan 28 = 9239
Jan 27 = 9027
Jan 26 = 7584
Jan 25 = 6931
Total 57877 which is 4130 more than what GA tells me.
Where am I mistaking?
Re: Active Users report numbers do not add up
Now keep in mind GA does sampling so depending on how much data you have depends on the actual numbers that will be displayed, also it is not uncommon in GA because of this sampling and processing time of up to 48 hours for totals to change for the same time period from day to day. If you do a report today with a specific time frame and do that same report tomorrow it could come up with slightly different totals.
