Google Analytics Not Working? Common Errors & Fixes

Empty GA4 reports usually mean the tag is not installed, not published or has no trigger. Check the tag, publish GTM, then confirm with DebugView.

The Realtime report covers only the last 30 minutes and is empty without active users. Visit your site and verify the tag with DebugView.

(not set) means Analytics has no value for a dimension. Find which dimension is affected and fix the tag or event that should populate it.

Google says landing page shows (not set) when a session has no page_view event. Make sure page_view fires and is not delayed by consent or redirects.

Thresholds hide small-count rows to protect users. They are system-defined and cannot be changed; widen the date range or avoid demographic dimensions.

Only a few events are key events automatically. Mark your event as a key event and check the name matches exactly.

Standard properties keep event-level data 2 or 14 months; set it to 14 months. Only 360 offers longer, up to 50 months.

Google documents a 10 million event sampling limit per query on standard properties and 1 billion on 360. Shorten ranges or export to BigQuery.

Visitors who decline analytics storage are not fully tracked. Load Google tags before the banner so behavioral modeling can work once volume prerequisites are met.
