Operating in the Dark

The client saw a sharp drop in Enhanced Conversions, which began hurting ad performance. Our assessment pointed to Google Tag Manager configuration issues that were limiting coverage. The tracking showed sporadic spikes but mostly near-zero coverage, signalling a tagging/configuration problem that needed immediate attention.
