Overview
If the organic traffic or new user numbers in your Search Atlas reports do not match what you see in Google Analytics 4 (GA4), you are not alone. This is one of the most common integration questions our team receives. Discrepancies are almost always caused by differences in how each platform filters, attributes, or processes the same underlying data — not a broken connection. This article walks you through the most common root causes and general guidance to help you reconcile the numbers.
Common Root Causes
- Date range and timezone mismatches: GA4 applies your account timezone to all reports. If Search Atlas is displaying data in a different timezone, daily totals can shift — especially for sessions near midnight. Confirm both platforms are set to the same date range and timezone before comparing figures.
- Organic traffic definition differences: GA4 classifies sessions as organic based on its own channel grouping rules. If your GA4 property has custom channel groups or modified default channel definitions, the organic segment visible in GA4 may differ from what Search Atlas displays.
- New user attribution: GA4's definition of a "new user" depends on when GA4 first registers a Client ID. If a user clears cookies or switches devices, GA4 may count them as new again. Filters applied within GA4 can also affect these counts. Search Atlas reflects the data as received from GA4, so any GA4-side configuration affects both views.
- Filters and data streams: GA4 properties can have internal traffic filters, developer traffic filters, or cross-domain tracking configured. If these filters are applied inconsistently — or were added or changed after your Search Atlas integration was set up — the data visible in Search Atlas may not match your GA4 dashboard view.
- Connected property mismatch: If your GA4 account uses multiple properties, ensure Search Atlas is connected to the same property you are comparing against in GA4. Comparing data from different property levels will always produce different numbers.
Steps to Investigate
- Verify which GA4 property is connected. Check your integration settings to confirm the correct GA4 property is linked to your Search Atlas project, and that it matches the property you are reviewing in the GA4 interface.
- Align your date ranges and timezone settings. Make sure both GA4 and Search Atlas are showing the same date range. Check your GA4 property timezone setting and confirm it aligns with what Search Atlas is using.
- Review your GA4 channel groupings and filters. In GA4, check whether any custom channel groups, internal traffic filters, or cross-domain tracking rules have been configured. Changes to these settings on the GA4 side will affect the data Search Atlas receives.
