What criteria cannot be used to create a custom segment? The simple answer is ad type. When studying for the Google Analytics Individual Qualification (GAIQ) exam, many people experience difficulty differentiating how custom segments are formed. To clarify, ad type cannot be used as a criterion while forming a new segment because the Google Analytics segment building tool does not recognize it as a valid building block. The details provided in the paragraph below will make it much easier to identify these differences.
What is the Concept of the Custom Segment?
Custom segment allows separating the group of people or sessions from total data, so that analysis happens for particular users who came from certain cities, spent more than five sessions on the website, or bought some of the goods after visiting a specific page.
By means of segments, people can check how this group compares with total traffic, which is a great way to notice something that is unseen with common numbers.
The 3 Building Blocks Considered Valid for Creating a Segment
Legitimately constructing filters from three main components is how the segment constructor has the ability to create segments:
Dimensions
characteristics of the information you have, such as the source of traffic, location, device type, or browser. These specify the identity of the visitor or their origin.
Metrics — numerical indicators, for example, session, page views, bounce rate, or the duration spent on a website. These define numerical results.
Measuring user behavior
an outline of actions, for example, “The people viewed their homepage, put some items in their cart, and ran away from the checkout stage.” This means that it is possible to create a segment on the basis of various paths.
What you need to do is choose a dimension or a metric, use comparison operators, and set a value to develop your filter.
The Reason Why Ad Type Cannot Be Used
Ad type is the name given to the format that an ad falls under like a text ad, display ad or video ad. Here, ad type refers to the advertisement creative and not like a certain aspect of measuring user activities.
Segments are based on the information that sheds light on user interactions with the website – including where the users came from, what the users did, how long they stayed, and whether they converted. One step back from all that is ad type. It is connected with the characteristics of the advertising campaign, not related to the user’s session or behavior, and thus cannot be treated like a segment building element.
A Simple Way to Memorize It for the GAIQ Test
If a criterion asks “how does the user behave” or “what particular aspect can describe this session,” one can be sure it is a dimension or metric. In case an ad type is about the creative of the ad only, and does not deal with user actions, it cannot be used in segment creation.
This is a common GAIQ exam question, and the multiple-choice options typically look like this:
- Ad type
- Dimensions
- Metrics
- Sequences of user actions
Since dimensions, metrics, and sequences are the three actual building blocks of the segment builder, ad type is the one that doesn’t belong.

For the official breakdown of how segments and their filters work, Google’s own documentation is the most reliable source — you can find it in the Google Analytics Help Center’s guide to segments.
Frequently Asked Questions
What criteria cannot be used to create a custom segment?
Ad type. Custom segments are built from dimensions, metrics, and sequences of user actions — ad type describes the ad creative itself, not user behavior or session data.
What criteria can be used to create a custom segment?
Dimensions (attributes like location or device), metrics (measurements like sessions or bounce rate), and sequences of user actions (a specific order of events).
Why is ad type excluded from segment building?
Because it describes a property of the advertisement rather than a measurable attribute of the user’s session or behavior, which is what the segment builder is designed to filter on.
Is this a real Google Analytics exam question?
Yes, it’s a commonly referenced question from the Google Analytics Individual Qualification (GAIQ) certification exam.
Final Thoughts
What criteria cannot be used to create a custom segment? Ad type — because segments are built from dimensions, metrics, and sequences of user actions, all of which describe user behavior or session data rather than the format of an advertisement. Keeping that distinction clear is useful both for passing the GAIQ exam and for actually building segments that reflect real user behavior.
