What Is GA4 Migration Guide?
The process of moving from Universal Analytics (UA) to Google Analytics 4 is called GA4 migration. It makes sure that data tracking continues without a hitch and that you get superior insights.

Why GA4 Migration Is Important for Marketers
GA4 isn’t simply an upgrade; it’s a whole new way of collecting and analysing data.
Marketers need to move to GA4 for these important reasons:

- A better grasp of how users move through your site
GA4 keeps track of consumers across devices and platforms, giving you a full picture of their journey as a customer.
- Measurement that protects privacy
GA4 is designed to work without needing a lot of cookies, which means it will still work with new rules in the future.GA4 Migration Guide
- Building smarter audiences
GA4 lets you construct more advanced audiences for remarketing and customisation.

- Relying Only on Default GA4 Setup

Why it’s wrong :- GA4 can’t effectively assess engagement or user intent without the right events.
- Forgetting to Mark Key Events as Conversions
Marketers need to do more than just keep track of events; they also need to say which ones are conversions. A lot of people forget this step.
Why it’s wrong :- GA4 can’t track leads, sales, or campaign success without conversions.
- Expecting Universal Analytics–Style Reports
Reporting in GA4 is not the same as in Universal Analytics. A lot of the time, marketers check for outdated UA reports and get puzzled or angry.
Why it’s a bad idea :- GA4 is more about exploring and user journeys than static reports.
- Ignoring Google Tag Manager (GTM)
Some marketers install GA4 directly on the website and skip Google Tag Manager.
Why it’s a mistake:–
Without GTM, managing events, tags, and future changes becomes complicated and time-consuming.
