SUMMARY
Fixing Broken Tag Infrastructure for a $15B+ Agency — and Delivering Measurable Campaign Gains
Atidiv partnered with one of the largest agencies in the digital media space — generating $15B+ in annual revenue, with 10,000+ employees across 100+ countries — to take over end-to-end tag management via Tealium IQ. The agency had onboarded a global client using Tealium IQ but was experiencing data integrity issues that were undermining tracking accuracy and campaign performance. Within 15 days of onboarding, Atidiv fixed tags across 600+ pages and implemented third-party tags for 40+ partners. By 60 days, Atidiv had expanded support to 3 new verticals — delivering a 25% decrease in CAC, 35% improvement in conversion rate for retargeting, and a 20% increase in CTR.

CHALLENGE
Data Not Passing Through Correctly — Tag Integrity at Risk Across a Global Client
The agency had onboarded a global client using Tealium IQ for tag management, but the data was not passing through correctly due to several interconnected issues. Inaccurate tracking was degrading campaign performance and creating blind spots across the reporting stack.
- Mismatch in event triggers for tag execution, causing inconsistency in tag firing across pages.
- Inaccurate information being passed through events, leading to corrupted data entering downstream platforms.
- Key data points missing in the tags, leading to incomplete tracking and gaps in audience and conversion data.
SOLUTION
Rapid Tag Remediation, Partner Implementation, and Scaled Vertical Expansion
Atidiv deployed a structured, phased approach — moving from immediate remediation to broader vertical expansion — ensuring the client had accurate, complete tracking from the ground up.
15 Days Post-Onboarding
- Fixed tags on 600+ pages and implemented third-party tags for 40+ partners across all pages — ensuring clean, consistent data flow from day one.
60 Days Post-Onboarding
- Onboarded 3 new verticals, providing comprehensive tag management support to the agency with Tealium IQ across an expanded client base.
OUTCOME
Accurate Tracking Unlocked — CAC Down 25%, Conversions Up 35%, CTR Up 20%
By resolving the underlying tag integrity issues and expanding coverage across pages, partners, and verticals, Atidiv restored confidence in the data layer and drove direct, measurable improvements in campaign performance.
| 25% | Decrease in CAC for segmented audiences after fixing the tags |
