Why Wrapper Chain Analysis Matters

Performance Impact

Each wrapper adds latency. Identify slow ad servers and optimize your chain for faster delivery.

Chain Validation

Ensure wrappers follow IAB guidelines and don't exceed recommended depth limits.

Error Detection

Spot redirect loops, broken chains, and server errors before they impact ad delivery.

Tracking Events Across Wrapper Chain

Every wrapper hop in the chain can have its own tracking pixels. We capture and display all of them.

Complete Tracking Visibility

Each wrapper in the chain can add its own impression pixels, tracking events (start, quartiles, complete), and click-through URLs. Our analyzer captures all tracking events from every hop, giving you complete visibility into which parties are tracking your ad delivery.

Aggregate Tracking Metrics

See total counts of impression trackers, video event trackers, and click tracking URLs across the entire wrapper chain. Quickly identify if tracking implementation is complete or if any critical pixels are missing at specific hops.

Per-Hop Tracking Analysis

Each wrapper hop displays its own tracking events separately, making it easy to audit which ad server or SSP is adding which tracking pixels. This is critical for diagnosing discrepancies in reporting between partners.
