Session Duration suddenly dropped

We have experienced a constant Avg. Session Duration Since February of 1.20min .

 

But the odd thing is that from 1 day to another the Avg. session duration suddenly dropped unexpectedly.

We start thinking about spam, bots , everything , so we filter spam in our analytics we block bot from our website.. But the constant 1.20min is very weird .

 

What do you think??

Hi @adrian g - there are a couple of things to check aside from spam which I doubt is the reason.

 

1) has anything changed in GA implementation

2) has the site changed in any way

3) has the session duration in GA property admin been changed

 

The change itself is very radical so I suspect something changed system wise.

 

Other ideas would be to:

1) check the avg session distribution with segmenting sources / geo / devices

2) check other metrics to see corelation

 

Hope it helps!

 

Kind regards,

Thanks for the answer .

 

Yes there has been some changes but curious thing is that this changes began 3 weeks after the day the the session dropped:

 

1) has anything changed in GA implementation

We've migrated to GTM

2) has the site changed in any way

Not in FrontEnd , but we finally add an SSL Certificate

3) has the session duration in GA property admin been changed

The configuration from sessions is the default 

 

Session timeout
H 0 M 30

Campaign timeout
M 6 D 0 H 0 M 0

but we noticed that USER ID is activated. That this is something new for us.

 

Thank you
