👉 Struggling to match GA4 sessions with your ad platform clicks?
💡 Blame GA4 attribution.
Here’s the catch: GA4’s default session source rewrites attribution, so paid traffic often gets credited to organic or direct.
If you want like-for-like with your ad platform, use manual UTM session source.
Rule of thumb:
Manual = accuracy for reconciling paid traffic
Default = insights for multi-channel journeys
