Migrating from Universal Analytics to GA4 is more than switching a tag. GA4 uses a completely different data model, and a sloppy migration means months of bad data. Adslytics maps your existing UA goals, events, and segments to their GA4 equivalents — and builds a clean, future-proof GA4 configuration that captures the same business insights your UA setup did.

Frequently Asked Questions

Yes — many sites still have misconfigured GA4 from rushed migrations and need a clean rebuild to get accurate data.
UA stopped collecting data in July 2023. Historical UA data remains in your UA property for export but cannot be moved into GA4.
The metrics are not directly comparable due to the different data models. We document the differences so you can interpret changes in your data correctly.
We reconfigure Google Ads conversion tracking to use GA4 key events, ensuring your campaigns continue to optimise correctly.
We map each UA goal to the equivalent GA4 conversion event and verify each one fires correctly in the new setup.
Typically 3–5 business days for a standard website migration.
Many UA custom reports have GA4 equivalents. We document the translation or rebuild them in GA4's Explore tool.
GA4 uses audiences and explorations rather than segments. We recreate your key UA segments as GA4 audiences or exploration filters.
If you use Looker Studio, Data Studio, or other BI tools connected to UA, those will need to be reconnected to GA4.
We migrate custom dimensions to GA4's user and event-scoped custom dimensions with equivalent data capture.
