We just read a great piece by Jesse Nichols on advanced segment logic and thought it might be a good idea, as part of our “Back To Basics” series, to expand on that a little.
Advanced segments are essential in filtering your data so you can dive deep and get clean insights. However, you might have to blow the dust off your old symbolic logic text books, cause this stuff can be confusing. Getting the logic wrong could mess up your data analysis and reports.
Hopefully, the diagrams we made here will help you remember your “and’s” AND “or’s”. Or, I guess it would be your “and’s” OR “or’s”…(Anyway, whatever…)
When creating Google Analytics advanced segments, you can “include” or “exclude” dimensions.
We’ll go through the following:
For non-exclusive dimensions (dimensions that can overlap, like place and kind), the following is a visual representation of how it will work. (We’ll go through exclusive dimensions – dimensions that don’t overlap, like two different places).
Let’s break this down in terms of the potential Google Analytics dimensions we’ll be looking at.
Let’s say:
Include “this” AND Include “that” (This and That). You’re looking for traffic that is U.S. and paid. You might translate “Include U.S. Traffic and Include paid traffic” into normal English, “I want U.S. traffic and paid traffic”. The latter implies you want both, which is where the confusion happens. In actuality, you are looking for where they overlap. Thus, in our diagram, you are looking for the dark grey color.
Include “this” OR “Include “that” (This or That). Translating this into English would sound like “I want U.S. or paid traffic”, which sounds exclusive – “I want either U.S. or paid traffic”, which sounds misleading. You will be pulling up “either or” as well as the overlap. If the condition hits either case (which includes if it hit’s both), it will be included. In our diagram, this corresponds to the dark and light grey.
Exclude “this” AND Exclude “that” (Not This and Not That). “Not U.S. and Not paid traffic”. A little tricky. In traditional symbolic logic, “And” means both conditions need to be satisfied. You would think then that this is an overlap. Actually, you’re not getting rid of the overlap, you’re getting rid of both cases. That means anything that is from the U.S. will be eliminated as well as all paid traffic will be eliminated . Thus everything that is grey will be gone. You will only be looking at the orange universe.
Exclude “this” OR Exclude “that” (Not This or Not That). “Not U.S. or Not paid traffic”. To me, this is the most confusing one. Again, traditionally, you’re thinking “OR”, which is both data sets. That’s not correct.
To understand this one, let’s look at “include ‘this’ or include ‘that’ “ for a second. The logic behind this implies: The data set either has to have “this” or has to have “that”.
Along the same lines, for “exclude”, if we take that italicized part of the previous sentence and insert “NOT”, you get this:
The data set has to NOT have ‘this’ or NOT have ‘that’.
Meaning, if the data set doesn’t have one of them or is missing one of them, it checks out.
Let’s go through each color area we have and compare it to that last logical sentence.
Conclusion? This advanced segment eliminates the dark grey overlap! So here, you are looking at the orange universe and the light grey. In other words, you are filtering out U.S. Paid traffic.
What happens when you have dimensions that are mutually exclusive? For example, U.S. traffic and Canada traffic? (Another example of sets that don’t overlap is if U.S. has no paid traffic). Things become a little different.
Include “this” AND Include “that” (This and That). It’s impossible that one visit will fall under both locations (unless you have the power to teleport or go warp speed, in which case, you’d have to also be surfing the net during that time). Thus, you’ll get nothing from this segment, as they never overlap!
Include “this” OR Include “that” (This or That). This would be either U.S. or Canada traffic. Thus, you’ll get both (light) grey colors from this segment.
Exclude “this” AND Exclude “that” (Not This and Not That). Similar to non-exclusive dimensions or sets, you’re just getting rid of both. Thus, in our diagram, you’re left with the orange universe. Anything that is not either one.
Exclude “this” OR Exclude “that” (Not This or Not That). “Not U.S. or Not Canada traffic”. If we look at the non-exclusive diagram, you are getting rid of the dark grey overlap. Since there is no dark grey overlap in this diagram, you’re not really getting rid of anything. Thus, this is a moot segment when dimensions are mutually exclusive.
To analytics ninjas, the obvious segment you would want to create to analyze “U.S. paid traffic” is “Include U.S. and Include Paid Traffic”. When filtering for mutually exclusive dimensions like U.S. and Canada, “Include” and “OR” would be the way to go. Of course, there are a bunch of different combinations that will create different logic, but hopefully, these diagrams will help remind everyone of the basics to build on.
