We’ve been running a session timeout configuration of 7 hours and 55 minutes on our website for 24 days now. Below is the proportion of sessions with landing pages (not set) for the 24 days before the session timeout change was made.
Looking at the 24 days since the change, landing page (not set) sessions decreased from 11.27% to 2.87% – a huge difference overall.
There are still some sessions with landing page (not set) coming through, but we never expected this solution to completely remove this issue because user behaviour isn’t always going to fit the parameters chosen to solve this problem – in this case session timeout.
Also, internet (and web analytics) can provide weird and wild metrics that make no sense occasionally!
