when looking at the Channel Report (Reports → Acquisition → Channels), I can see the individual entries for the channels. When I sum up each channel, I’ll get a different summary than the one displayed at the top.
Top says: 70
Direct entry = 42; Campaign = 20; Search engine =5; Social =3; Website =1 → 42+20+5+3+1= 71
I’ve attached a screenshot for clarification.
Can please somebody explain to me why there’s a difference?
Here is how it works:
Let’s imagine there’s single visitor:
This visitor starts two sessions, one through campaign other through social
What we will see in reports is:
Visitors total: 1
Campaign: 1
Social: 1
It’s not a bug then, the visitors dimensions is a unique number of visitors, but one visitor can come to your website through multiple sources.
