Web Analytics Google Analytics 1 — Questions and Answers
Question 1: In GA4, which metric measures the percentage of sessions where users engaged with your site for more than 10 seconds, had a conversion event, or viewed 2+ pages?
- Bounce Rate
- Engagement Rate (Correct answer)
- Session Duration Rate
- Active User Rate
Correct answer: Engagement Rate
Engagement Rate in GA4 is the percentage of sessions classified as 'engaged sessions' — those lasting over 10 seconds, containing a conversion event, or including 2 or more page/screen views. It replaced the traditional bounce rate as the primary session quality metric.
Question 2: What is the GA4 'data stream' concept used for?
- Streaming real-time data to BigQuery
- Connecting a data source (web, iOS, Android) to a GA4 property (Correct answer)
- Filtering bot traffic from reports
- Importing cost data from Google Ads
Correct answer: Connecting a data source (web, iOS, Android) to a GA4 property
A data stream in GA4 is a pipeline that connects a specific platform — a website, iOS app, or Android app — to a GA4 property. Each property can have multiple data streams, allowing unified cross-platform measurement.
Question 3: Which GA4 feature allows you to group users based on shared attributes and then apply those groups retroactively to historical data?
- Custom Dimensions
- Audience Triggers
- User-scoped Segments (Correct answer)
- Predictive Metrics
Correct answer: User-scoped Segments
User-scoped segments in GA4 Explorations evaluate all sessions and events for a user once that user meets the segment criteria, effectively applying the segment across their historical activity within the lookback window.
Question 4: In GA4, what is the default attribution model used in standard reports?
- Last Click (non-direct)
- Linear
- Data-Driven (Correct answer)
- First Click
Correct answer: Data-Driven
GA4 uses Data-Driven Attribution (DDA) as the default model for standard reports. DDA uses machine learning to assign fractional credit to touchpoints based on how each channel actually contributes to conversions, rather than applying fixed rules.
Question 5: What does the GA4 'session_start' event do?
- Fires every time a user views a new page
- Triggers when a user completes a purchase
- Automatically fires when a new session begins and assigns a session ID (Correct answer)
- Marks the beginning of a new user lifecycle
Correct answer: Automatically fires when a new session begins and assigns a session ID
The 'session_start' event is automatically collected by GA4 whenever a new session begins. It generates a unique session ID (ga_session_id) used to group all subsequent events within that session together in reporting.
Question 6: In GA4 Explorations, what is the purpose of the 'Funnel Exploration' technique?
- To visualize the geographic path users take before converting
- To show the sequence of steps users take toward a goal and where they drop off (Correct answer)
- To compare two audience segments across all dimensions simultaneously
- To display a cohort of users grouped by their first-visit date
Correct answer: To show the sequence of steps users take toward a goal and where they drop off
Funnel Exploration in GA4 lets you define a sequence of steps (events or page views) representing a user journey and visualizes completion and drop-off rates at each step, helping identify where users abandon a conversion flow.
