The use of Advanced Segments on Google Analytics can be very valuable in giving us a deeper and more accurate picture of performance. Segments allow us to run a control group analysis in which we can isolate different groups of users and compare them to show us where we should be allocating future investments and strategy.
In measuring social’s impact on consideration and conversion, Google Analytics defaults to last-touch attribution, which provides a very narrow view and gives minimal credit to the channel. However, we can create segments that measure the behavior of social media users and compare them to users who do not touch social in order to gain valuable insight as to how each marketing channel impacts our KPI. You can do this type of control group analysis for any group of users by creating Custom Segments.
