Overview

Header Bidding, done properly

A well-built header bidding wrapper is the highest-leverage revenue project a publisher can undertake. We design, deploy, and manage Prebid.js and server-side (Prebid Server / TAM) setups tuned for your traffic profile — balancing bidder density against latency, enforcing timeout discipline, and continuously pruning underperforming partners. The result is more competition on every impression without hurting Core Web Vitals.

  • +15–30% programmatic uplift over waterfall setups
  • Sub-1000ms auction budgets
  • No Core Web Vitals regression

Ongoing analysis of bid rates, win rates, timeouts, and revenue per bidder.

Identity & consent integration

UID2, first-party IDs, and CMP integration configured for maximum addressability, compliantly.

FAQ

Header Bidding — common questions

Client-side or server-side — which is better?

Usually both. Client-side auctions win on identity match rates; server-side wins on speed and scale. We benchmark bidder-by-bidder and place each where it earns the most.

Will header bidding slow down my site?

Not when built correctly. We enforce strict timeout budgets, lazy auction initiation, and asynchronous loading so revenue never comes at the cost of user experience.

How many bidders should we run?

Density helps until it doesn't. Most sites peak between 8 and 15 well-chosen bidders; we prune continuously based on net contribution.
