Questions
Frequently asked questions
Everything you need to know about prebid monitoring and header bidding analytics.
What is Prebid Monitor and how does it work?
Prebid Monitor is a real-time header bidding analytics platform that monitors prebid.js auctions across 60+ publisher websites. Using advanced browser automation with stealth technology, the system visits publisher sites in parallel batches, intercepts prebid.js auction events, and captures every bid response, CPM, latency metric, and demand partner participation data. This competitive intelligence is then processed and presented through an interactive dashboard for programmatic advertising professionals.
Which demand partners and SSPs does Prebid Monitor track?
Prebid Monitor currently tracks 26+ unique demand partners and SSPs including Criteo, Index Exchange (ix), Ozone, MediaNet, Yahoo Ads, Teads, AppNexus, Rubicon Project, PubMatic, OpenX, Sovrn, TripleLift, GumGum, Amazon TAM, Sharethrough, 33Across, Kargo, Yieldmo, and more. Our coverage is continuously expanding as we detect new bidders participating in header bidding auctions across monitored publishers.
How is this different from prebid analytics adapters like AsterioBid or PubWise?
Traditional prebid analytics adapters require code installation on your own website and only show you your own auction data. Prebid Monitor provides competitive intelligence by monitoring external publisher websites, giving ad tech companies, SSPs, and programmatic teams a market-wide view of header bidding activity, demand partner coverage, pricing trends, and bidder performance across the open web — without requiring publisher cooperation or integration.
What header bidding metrics and KPIs are tracked?
The dashboard provides comprehensive prebid analytics including: sites monitored, total scan volume, average winning CPMs, total bids captured, unique active bidder count, average bid response latency, per-bidder win rates, CPM trend charts over time, demand partner performance rankings, per-publisher drill-down analytics, ad unit level data, timeout tracking, floor price monitoring, and historical trend comparisons across 7-day and all-time windows.
Who should use Prebid Monitor?
Prebid Monitor is built for programmatic advertising professionals including SSP business development teams evaluating market coverage, ad tech companies analyzing competitive positioning, yield optimization specialists benchmarking publisher performance, publisher monetization teams comparing their header bidding setup against peers, and anyone who needs real-time competitive intelligence on header bidding activity across the programmatic advertising ecosystem.
How often is header bidding data updated?
Prebid Monitor runs continuous scan cycles across the monitored publisher network, processing sites in parallel batches of 10 with smart polling technology. Data is updated in the dashboard after each scan cycle completes, providing near real-time visibility into header bidding auction activity. The system operates 24/7 with automated health monitoring and smart pause functionality for sites experiencing issues.
