62% Reduction in Wasted Ad Spend via GTM Audit
The Challenge
A hotel group was spending €30k/month on Google Ads but had severe tracking issues: duplicate conversions, misfiring tags, and audiences built on junk data. Their campaigns were optimizing towards ghost conversions.
The Solution
Full GTM container audit revealed 14 duplicate tags and 3 conflicting conversion actions. Rebuilt the container from scratch with proper QA documentation. Fixed attribution, cleaned up conversion actions, and rebuilt Smart Bidding audiences.
The Result
Wasted ad spend dropped by 62% within the first month. With clean data, campaigns shifted budget to highest-performing channels automatically.
