What is the difference between Universal Analytics and GA4?
Universal Analytics, the previous version of Google Analytics, was released in 2013. GA4 is the latest Google Analytics version, released in 2020, and offers several significant differences in terms of its event tracking, cross-device functionality, and machine learning capabilities.Data model: Universal Analytics uses a session-based data model, which tracks a series of user actions on a website as a single "session". GA4, on the other hand, uses an event-based data model, which tracks individual user actions, such as page views, clicks, and form submissions, as separate events. This allows GA4 to collect more detailed and granular data about user behaviour.Automatic event tracking: GA4 automatically tracks a wide range of events on your website without requiring manual configuration. This includes page views, clicks on buttons and links, form submissions, and other interactions. Universal Analytics, however, requires manual configuration to track events, which can be time-consuming and error-prone.Enhanced data collection: GA4 uses machine learning to collect and analyze data from various sources, including website interactions, app usage, and customer interactions across channels. This allows it to provide a more complete and accurate picture of customer behaviour and preferences. Universal Analytics is limited to tracking data from website interactions.Improved reporting and analysis: GA4 provides more detailed and customizable reports and new tools for analyzing customer behaviour and predicting future trends. It also includes new features such as "path analysis" and "funnels", which allow you to visualize and analyze the different steps users take on your website. Universal Analytics has more limited reporting and analysis capabilities.Improved integration with other Google products: GA4 is closely integrated with other Google products, such as Google Ads, Google Marketing Platform, and Google BigQuery, making it easier to analyze and optimize your marketing efforts across different channels. Universal Analytics has limited integration with other Google products.Data retention: GA4 includes new data retention controls that allow you to specify how long data is retained before it is automatically deleted. This can be useful for complying with data privacy regulations such as GDPR. Universal Analytics does not have this capability.

You will then need to update any custom tracking code, integrations, reports and other configurations that you have set up in UA to GA4. Once you have completed the migration, you can retire your Universal Analytics property and tracking code. Please see the checklist we have prepared to assist you in the migration
Will my existing data be lost if I migrate from Universal Analytics to GA4?
The historical data will be available in Universal Analytics after the end-of-life for at least 6 months, and you can still use that in read-only mode. UA captures no new data after it reaches the end of its life. We recommend you set up GA4 now along with UA to track the website analytics in GA4 and then take steps to migrate the custom configurations and reports to GA4. Once UA reaches the end of life, you can remove the UA tracking code from your website.You should also take steps to export existing data before Google shuts down UA completely. For the free version of Google Universal Analytics, the BigQuery connection is not available by default. You may need a 3rd party connector to back up your historical data. Matomo offers a GA Data Export plugin to move your data to Matomo.
We are using 360 Universal Analytics. Is there any difference?

We are a SME, and using UA as it is. Ie we did not made any customization, just using the default reports. Do we have to prepare for anything?
Users with default UA configuration have nothing to worry about; they can use the one-click creation of GA4 tags and set up the tracking code in their websites/apps.GA4 is a different product, and the user interface and reports have changed. There will be a learning curve to start using the new system.Please note that even if you migrate your UA to GA4, you still need to install the new GA4 tracking code in your website or tag manager and double-check the configuration to ensure that the data is being accurately tracked.

Will custom events created in GTM work in GA4?
Yes, Custom events created in Google Tag Manager (GTM) will work in Google Analytics 4 (GA4), as long as you've set up your configuration tag to send your data to GA4. GA4 allows you to use existing triggers that you've used for Universal Analytics (UA) to send events to GA4.
Is there a report available for session duration in GA4?
GA4 focuses less on the idea of sessions and more on engagements. While there may not be an out-of-the-box report for session duration in GA4, you can build custom reports in the Explore section by playing around with metrics and dimensions.
Is GA4 suitable to track multiple domains and subdomains?
Yes, absolutely. All of your tracking in GTM can be sent to the same data stream. It's good to just have one data stream, but if you have your domain and your subdomains, you can send that to the one data stream if you want.
What's the difference between data streams in GA4 and views in UA?
A data stream is the source of your data, while a view was more like a filtering of data that was already there. In GA4, we have comparisons, which are kind of like a segment you can apply. We don't go into much detail on comparisons in this session, but we will later on.
How can we evaluate user data for different platforms separately, web and app?
If a user's data is captured against a single user ID, GA4 provides differentiation. While we have that consolidated idea of user ID, in the data model, we'll still always have those dimensions attached, or the parameters attached, saying, web, app, page view, screen view, where you can separate, or segment, or filter for just the web session or just the app session.
Is there any mechanism to track invalid traffic?
GA4 automatically detects bot traffic, so that will be excluded by default. In internal traffic, there is a parameter you can attach to traffic called Traffic Type (traffic_type). So whatever you're using for tagging, GTM, for example, you can have a parameter attached to a user with Traffic Type Internal. That will be excluded.
Can we add additional parameters to the default page view event?
Yes, you can set up automatically collected parameters that you want on all of your page views and use properties if that applies as well. However, these parameters will only apply once to the page you're on, so they should be page-level values.
Can page path be an example of a high cardinality custom dimension?
No, the page path is automatically collected and not high cardinality. You do not need to create a custom dimension for page_path. A high cardinality dimension isn't automatically collected, like article ID, which would be a custom dimension you must tell GA4 to collect and recognize as custom.
Do I have to migrate to GA4? Is there any alternative options?
If you are looking for a privacy-first website analytics platform, you should give a try to Matomo or Plausible based on your business need.
Is it possible to create custom channel groups in Google Analytics 4?
