Rebuilding the header bidding setup of a high-traffic news publisher

The publisher ran a legacy Prebid configuration with an oversized bidder list, no floor strategy and a 3-second timeout that suppressed bid density on mobile. Reporting was assembled manually from six dashboards.

We restructured the wrapper, cut underperforming bidders, introduced dynamic floors with continuous A/B testing, tuned timeouts per device, and shipped a unified reporting pipeline reconciling ad server and SSP data daily.

Custom server-side VAST infrastructure for a video-heavy publisher network

Client-side VAST chains were producing high error rates and slow ad starts, and third-party tag limitations blocked the demand mix the client wanted to run.

We built a server-side VAST wrapper layer with response caching and macro handling, enabling clean multi-demand waterfalls, faster ad starts and full visibility into error codes per demand source.

Taking over ad operations for a mobile game studio

A growing game studio had no in-house ad ops. Mediation was set once and never revisited; new demand partners took months to onboard and eCPM trends went unmonitored.

Openbidx became the studio's outsourced ad ops team: continuous mediation optimization, structured demand partner onboarding, daily eCPM and ARPDAU monitoring with alerting, and monthly performance reviews with the leadership team.

Ad Manager restructuring and unified reporting for a multi-site publisher

Years of ad-hoc changes had left the client's Google Ad Manager with thousands of stale line items, inconsistent key-values and unreliable reporting that finance could not close the month on.

We redesigned the inventory structure, migrated to a clean naming and targeting taxonomy, archived legacy objects safely, and delivered automated revenue reports that reconcile with billing at under 2% discrepancy.
