Connecting Google Analytics (GA4)

Connecting GA4 overlays real traffic and conversion data on top of audits and rank tracking. We support GA4 only – Universal Analytics shut down in 2023.

Prerequisites

• You have at least Read & Analyze role on the GA4 property.
• GA4 is enabled (not legacy Universal Analytics).
• The Google account you authorize with can see the GA4 property in the GA4 UI.

Connection flow

1. Settings → Integrations → Google Analytics 4 → Connect.
2. OAuth window opens. Pick the Google account that owns the GA4 property.
3. Grant analytics.readonly + userinfo.email scopes.
4. A modal asks which GA4 property to use – pick from the dropdown.
5. Save. We backfill the last 28 days immediately.

Read-only – we cannot modify GA4 settings, add events, or change anything.

Data we pull

API quota

GA4 Data API has a per-property quota of 250,000 tokens/day and 10 concurrent requests. Initial backfills for very large properties (50M+ events/month) can hit quota; we retry with backoff and the initial sync usually completes within an hour.

Sync cadence

Incremental sync every 6 hours after the initial backfill. Data lag is typically 1-3 hours behind GA4. You can trigger an on-demand resync from Settings → Integrations → Google Analytics 4 → Manage.

Time zone behaviour

We use your SEMOptimiser workspace timezone for date bucketing. GA4 uses the property timezone configured in GA4 itself. If they differ, daily totals on adjacent days may not match. Set both to the same timezone for clean reconciliation.
