I have recently inherited responsibility for an old site and its GA profile. When looking at the Source/Medium I can see the regular referrals such as Twitter and Google. But there are some referrers that I don't understand. Maybe they are custom codes set up by the previous administrator.
Here are some of the results for Source / Medium reports:
- 1 / more
- 2 / 21024
- 2 / 51018
Where can I look to find out more about these referrers in my GA account?
