Search engines appearing in Referral traffic report
When looking through my referral traffic report I have noticed that there are search engines in this such as uk.search.yahoo.com and search.bt.
I access the referral traffic report by going into Acquisition > All Traffic > Referral
My questions are:
1) Does anyone know why they are classed as referral?
2) Is there a way to get rid of them from the report without creating a segment and created lots of excludes in the advanced filter?
