How would I know the day it starts?
- Feder reads your page views and sessions from Google Analytics each day and compares each day with your own history.
- Feder does not sort traffic by channel, so it does not flag Unassigned traffic itself. It tells you when visits go quiet or move outside your usual range.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See what Feder reads from Google Analytics, which feeds Visits. Feder only reads. It never changes anything in Google Analytics.
