Understanding GA4 Property Creation

When setting up a new Google Analytics 4 property, which of the following is required to start collecting data?

A Linking the GA4 property to a Google Ads account

B Adding the GA4 tracking code (Measurement ID) to your website or app

C Creating a Universal Analytics property first

D Setting up conversion events manually before data collection

💡 Hint

Think about what connects your website or app to GA4 to send data.

To collect data in GA4, you must add the GA4 tracking code, identified by the Measurement ID, to your website or app. This code sends user interaction data to your GA4 property.

Linking to Google Ads is optional and done later for advertising insights. Universal Analytics is a previous version and not required. Conversion events can be set up after data starts flowing.

Default Data Streams in GA4

Which types of data streams can you create in a Google Analytics 4 property to collect data?

A Website, Mobile app, and Social media streams

B Website, Mobile app, and Email campaign streams

C Website, Mobile app, and Offline store streams

D Website, Mobile app, and Server streams

💡 Hint

Consider where GA4 can collect data from directly.

GA4 supports three types of data streams: Website (via web tracking), Mobile app (via SDKs), and Server streams (for server-side data collection).

Email campaigns, offline stores, and social media are not direct data stream types in GA4.

Configuring Enhanced Measurement in GA4

You want GA4 to automatically track page views, scrolls, outbound clicks, and video engagement without adding extra code. What should you do during setup?

A Enable Enhanced Measurement in the data stream settings

B Manually add event tags for each interaction in Google Tag Manager

C Create custom events in GA4 after data collection starts

D Link GA4 to Google Ads to enable automatic tracking

💡 Hint

Look for a built-in GA4 feature that tracks common interactions automatically.

Enhanced Measurement is a GA4 feature that automatically tracks common user interactions like page views, scrolls, outbound clicks, and video engagement without extra coding.

Manually adding tags or creating custom events is more work and not needed for these basics. Linking to Google Ads is unrelated to this feature.

🔍 Analysis

Analyzing GA4 Event Parameters

In GA4, you notice an event named purchase with parameters value, currency, and items. What is the best explanation of these parameters?

A <code>value</code> is the discount applied, <code>currency</code> is the country code, and <code>items</code> is the customer ID

B <code>value</code> is the number of items, <code>currency</code> is the payment method, and <code>items</code> is the shipping address

C <code>value</code> is the total purchase amount, <code>currency</code> is the currency code, and <code>items</code> lists the products bought

D <code>value</code> is the tax amount, <code>currency</code> is the store location, and <code>items</code> is the payment type

💡 Hint

Think about what information is important to describe a purchase event.

In GA4, the purchase event typically includes value as the total amount spent, currency as the currency code (like USD), and items as an array listing the products purchased.

Other options confuse these parameters with unrelated data.

Troubleshooting Missing Data in GA4

After setting up GA4 on your website, you notice no data appears in reports 24 hours later. Which is the most likely reason?

A The GA4 Measurement ID was not correctly added to the website's code

B The GA4 property was created but not linked to Google Ads

C Enhanced Measurement was disabled in the data stream settings

D The website has no visitors in the last 24 hours

💡 Hint

Consider what is essential for data to flow from the website to GA4.

If no data appears after 24 hours, the most common cause is that the GA4 Measurement ID tracking code was not properly added to the website, so no data is sent.

Linking to Google Ads is optional and does not affect basic data collection. It's unlikely the site had zero visitors. Enhanced Measurement being off only limits automatic event tracking but does not stop all data.
