In our data, we often see it happen that the very first sessions of a domain_userid has as refr_medium ‘internal’. I want to know the reasons why this can happen.
Clearly, when cookies have been deleted with the website still open, and the user continues using the website, this will result in a first session of a domain_userid to have a refr_medium equal to ‘internal’.
Moreover, this could happen when data of the actual first page view does not enter the database, due to for example bad rows. Hence, only the second page view makes it to the database, it being internal.
Are there any other reasons why this may happen?
When a website has an internal redirect when entering the website, this also results in an internal session.
