An example of a hit-scope Phone Number Database dimension is 'page URL'. This is sent along with every interaction, because each interaction could be on a different page. The value of the 'traffic source' dimension is only known at the beginning of a session. Still you want to link all interactions during the session to Phone Number Database this traffic source. This is possible because there is only one traffic source per session and we can therefore use the scope session. The same goes for a dimension with scope user. A user has Phone Number Database only one place of residence. That means that if we find out what his place of residence is somewhere during his customer journey, we can link all interactions to that specific place of residence.

Scoping by segments Segments Phone Number Database use scope to make selections of users and sessions. You make these selections because you do not want to analyze the entire data set, but only part of it: the segment. Basically Phone Number Database you say: I want to do an analysis of all sessions or users that meet a certain condition. Let's say we want to use segments in the example above. Then, depending on Phone Number Database which experiment we want to analyze, we look for a segment that satisfies the condition that a session or user has been in contact with a certain experiment.

If we choose the scope 'session' and want to analyze experiment 1, then during the segmentation session #1 is matched and the Phone Number Database interactions 1 to 3 fall into the segment. You can immediately see that this is not correct. We do not want to relate interaction #1 to the experiment. We can give another example Phone Number Database by choosing the scope 'user' and experiment 2. With this selection, user is matched and all 7 interactions fall within the segment. This while interactions 1 to 4 preceded the Phone Number Database experiment. Again, it is clear that this selection is incorrect. It mainly goes wrong here, because the wrong scope is chosen. The choice of user or session does not match the experiment.
