My question relates to visitors that have only visited one page and taken no further action and where no heartbeattimer is used.
Here https://matomo.org/faq/how-to/faq_21824/ is written:
When your visitor views only one page in the website, the “Visit” duration will be set to a default of 10 seconds
and here https://matomo.org/faq/how-to/faq_21158/
when the visitor views only one page view, the “Time on Page” will be 0 seconds and the “Visit duration” will be 10 seconds.
and here is written:
when the visitor views only one page view, the "Visit duration" will be 0 second.
It seems to me that the third statement is correct (0 second).
Otherwise it would not be possible for such low values to appear here.
I think we might actually have changed that behavior somewhen in the past. But can't remember when or why. Maybe with introducing the HeatBeat 🤔 @tsteur can you remember?
But I think when not using HeatBeat
0s should be default.
I don't remember but looking at the code I can see there is a config
default_time_one_page_visit that is set to 0s by default. So as part of this issue we should correct the wrong documentation.
Seems that had been changed back in 2010. I have updated the mentioned pages above and also mentioned that changing
default_time_one_page_visit can be used to set another default visit duration
