GA4 Setup Audit to Identify and Fix Configuration Issues
Trace every data problem back to its source and fix it there, before it compounds across every report in your stack.
Trace every data problem back to its source and fix it there, before it compounds across every report in your stack.



GAfix looks beyond surface settings to review how your entire GA4 setup is actually structured, so you’re not relying on defaults that may be misaligned underneath.
01
Validates GA4 enhanced measurement captures real user interactions accurately.
Missing auto-tracked interactions skew data
Misfires create false signals in reports
Silent gaps reduce trust in behavioral insights
Default tracking doesn’t always match real usage
Cleaner engagement metrics
More accurate content insights
Better funnel visibility
Stronger reporting confidence
Enhanced measurement configuration accuracy
Scroll, click, and download tracking
Event consistency across key pages
Auto-event coverage vs actual behavior
Engagement metrics feel inconsistent
Key actions missing from reports
Sudden drops in interaction data
Unsure what GA4 is auto-tracking
Pro tip : In most GA4 setup audits, enhanced measurement looks “on” but still misses key interactions. These GA4 setup issues quietly underreport engagement, GAfix surfaces what’s missing so you can fix gaps before they skew content and funnel decisions.
02
Ensures custom dimensions and metrics are structured, scoped, and usable.
Wrong scoping breaks reporting logic
Poor structure limits analysis depth
Hitting GA4 limits leads to data loss
Inconsistent naming fragments insights
Accurate segmentation and targeting
Reliable custom reporting
Clearer funnel analysis
Better decision-making inputs
Event vs user scope configuration
Parameter mapping and definitions
Naming conventions and structure
Usage limits and unused fields
Reports show inconsistent breakdowns
Segments don’t match expectations
Missing parameter-level insights
Confusion around dimension setup
Pro tip : A GA4 property audit often reveals mis-scoped or unused dimensions. These GA4 configuration issues don’t break reports, they weaken every insight, GAfix highlights structural gaps so your team can fix segmentation and reporting at the source.
03
Confirms GA4 maintains session continuity across domains without breaking journeys.
Session breaks distort attribution
Duplicate users inflate metrics
Funnels fragment across domains
Conversion paths become unreliable
Unified user journey tracking
Accurate conversion attribution
Cleaner funnel analysis
Better budget allocation decisions
Cross-domain linking setup
Session continuity across domains
Referral parameter handling
Journey stitching accuracy
Users duplicated across domains
Drop-offs during redirects
Conversions split across sessions
Traffic spikes after navigation
Pro tip : Many GA4 setup errors happen when sessions reset across domains. Attribution breaks silently, GAfix identifies where journeys are splitting so you can restore continuity and trust your conversion paths again.
04
Ensures internal and third-party domains don’t overwrite true traffic sources.
Session breaks distort attribution
Self-referrals break channel tracking
External tools distort traffic sources
Campaign credit gets reassigned
Accurate channel attribution
Cleaner source/medium data
Reliable campaign reporting
Smarter marketing decisions
Referral exclusion list setup
Self-referral detection issues
Third-party domain handling
Attribution path integrity
Payment providers show as referrals
Referral traffic spikes unexpectedly
Conversions tied to wrong channels
Source data feels unreliable
Pro tip : Referral spikes are often attribution leaks, not growth. These GA4 configuration issues reassign conversion credit, GAfix pinpoints the source so you can correct exclusions and keep budgets aligned with real performance.
05
Validates GA4 connects web and app data into one consistent user journey.
Web and app data stay disconnected
Journeys break across devices
Events become inconsistent
Lifetime value gets underreported
Complete lifecycle visibility
Accurate cross-device attribution
Better retention insights
Stronger product decisions
Web and app stream integration
Event consistency across platforms
User journey stitching logic
Platform-level data alignment
Web and app data don’t align
App behavior missing in GA4
Users counted multiple times
Incomplete lifecycle insights
Pro tip : When web and app data aren’t connected, journeys split without warning. Most GA4 setup issues here go unnoticed, GAfix exposes these gaps so your team can unify tracking and make decisions on complete lifecycle data.
06
Checks User-ID implementation to unify logged-in users across devices.
Same user counted multiple times
Cross-device journeys stay fragmented
Retention metrics become unreliable
Poor setup risks data compliance issues
True user-level visibility
Accurate lifecycle analysis
Better retention tracking
Reliable LTV measurement
User-ID implementation logic
ID consistency across sessions
Anonymization and compliance setup
Cross-device tracking accuracy
User counts feel inflated
Journeys break across devices
Retention data looks off
Logged-in users tracked inconsistently
Pro tip : A GA4 property audit often shows users counted multiple times across devices. These GA4 setup errors distort retention and LTV, GAfix flags identity gaps so you can fix tracking and rely on accurate user-level insights.
