Viewing Prebid Bidders and Demand Seats

Demand → Prebid is where you see which bidders are available, which you've configured seats on, and where you click through to edit a specific seat.

The page is not a column-based list — it's a card layout with two sections: bidders you've already configured seats for, and bidders available to add.

How to view​

  1. In Ad Manager (main) mode, confirm the right domain is selected.
  2. Go to Demand → Prebid.

The page header reads Prebid Demand Seats.

Page structure​

Header actions​

Upper-right of the page:

  • Tag IDs dropdown (shown if you have tag-ID import permission):
    • Upload All — bulk-import tag IDs from a CSV
    • Download All — export all current tag IDs
    • Download Template — a blank CSV template

Filter box​

Just below the page header:

  • Search input — filters bidder and seat cards by name as you type
  • State dropdown — active vs. archived seats (active by default)

Demand Seats section​

Cards for bidders you've configured seats on. Each card shows:

  • Bidder name (card title)
  • Seat label (if the bidder has a single seat) or enabled/disabled counts (if multiple seats — e.g. "3 enabled · 1 disabled")
  • Status badges: Enabled (green) / Disabled / Archived / S2S (server-to-server, if applicable)
  • Action button:
    • A + to add another seat if the bidder currently has one seat
    • A numbered button to open a modal with all seats for that bidder if there are multiple

Clicking a single-seat bidder card navigates to that seat's detail page. Clicking a multi-seat bidder card opens the Demand Seats modal, where you pick which seat to open.

Available Bidders section​

Cards for bidders that exist in Anima but don't have a seat configured on your account yet. Click a card (or its + button) to add a new seat.

Opening a seat​

A seat is your account's configuration for one bidder — credentials, tag IDs, and related settings.

From the Demand Seats section, open a bidder card (or pick a seat from the modal). The seat detail page is tabbed:

  • Seat — credentials and per-seat settings
  • Tag IDs — ad-slot ↔ tag-ID mappings
  • History — audit trail (existing seats only)

Debugging bidder activity​

Demand → Prebid doesn't display live bid metrics — no CPM, win rate, or bid rate on the cards.

To see whether a bidder is actually bidding on your traffic:

  • Dashboard → Monetization — break down by bidder for impressions, CPM, and win rate
  • Browser console on a page with the wrapper installed:
    • pbjs.getBidResponses() — current-page bid responses keyed by ad unit
    • pbjs.getAllWinningBids() — bids that rendered

See Wrapper Debugging for the full console-side signal list.
