Hosted Prebid Server

Add demand partners without adding weight to your pages

Every bidder in the browser costs your readers requests, CPU and waiting time. Our hosted Prebid Server calls demand partners from the server instead, so one request from the page reaches many buyers, at the traffic levels of national news sites.

Why server-side bidding

Client-side header bidding has a ceiling. Past a handful of bidders, each new one slows the page and the auction more than it earns. Prebid Server lifts that ceiling, but running it yourself means operating a high-traffic service and keeping every bidder adapter and consent rule current.

  • Lighter pages

    One request from the browser replaces a request per bidder, which matters most on mid-range phones.

  • Configured per site

    Bidders, parameters, floors and traffic shares are set for each of your sites on our side.

  • Country rules

    Partners only receive requests from the countries where they actually have demand.

  • Responses you can trust

    We check the markup of every bid before rendering, so mislabelled video or native never prints raw code into a slot.

A hybrid auction: the right bidders on each side

Bidders that depend on browser cookies, or that answer fast from the browser, stay client-side. Bidders that add latency on the page, or match well server to server, move to Prebid Server. Both compete in the same auction.

  • Server-side requests get a slightly shorter timeout than the page, so their bids arrive in time
  • Moving a bidder between client and server doesn't touch your pages
  • Cookie syncing runs from the browser and server to server

Consent and supply chain, handled for every partner

Demand partners disagree about where consent and supply chain fields belong in a bid request, and a misplaced consent string can mean no bid. Our layer in front of Prebid Server fixes that in one place instead of in your page code.

  • GDPR, GPP and US Privacy signals placed where each partner expects them, on OpenRTB 2.5 and 2.6
  • A complete supply chain object on every request, with valuad.io as a node
  • Per-partner request adjustments maintained by us

How it works

  1. 1

    We pick the split

    We look at your traffic and decide which partners run in the browser and which run on the server.

  2. 2

    We configure your account

    Bidders, floors, traffic shares and country rules are set on our side for each of your sites.

  3. 3

    We keep it current

    Adapter changes, consent updates and partner requirements are handled without work on your pages.

Questions publishers ask

Do I need to host anything?

No. Valuad runs Prebid Server and the service in front of it. Your pages talk to it through our header bidding wrapper.

Can I use Valuad demand from my own Prebid setup?

Yes. Valuad has its own bidder adapter in Prebid.js, released in 2025. Publishers who run their own Prebid can add Valuad demand for banner inventory as a bidder.

Does Prebid Server handle video?

Yes. It can return VAST for a player tag URL, returns an empty VAST response when there are no bids, and caches winning VAST for instream video served through Google Ad Manager.

Does server-side bidding lower match rates?

It can for bidders that rely on browser cookies, which is why those usually stay client-side. Server-to-server cookie syncing narrows the gap for the rest.
