If you wanted to gain insight into the traffic to your retail website, which dimension would you look at to determine whether it was coming from “organic search,” “referral,” or other places?
Explanation:
Channel Groupings are rule-based groupings of your traffic sources. Throughout Analytics reports, you can see your data organized according to the Default Channel Grouping, a grouping of the most common sources of traffic, like Paid Search and Direct. This allows you to quickly check the performance of each of your traffic channels.
The channels in the Default Channel Grouping meet the needs of most Analytics users, but if you have specific analysis requirements and want to label your traffic in other ways, you can:
· Create a Custom Channel Grouping (user level).
· Create a new Channel Grouping (view level).
· Edit the Default Channel Grouping (view level).
