Discover inventory and publishers

Use the power of forecasting to find inventory

Use the Marketplace to find inventory across all Google partners for open auction buying and deal making. You can browse for inventory by sites and apps, by publisher, and narrow down the results by searching for specific criteria.

Marketplace uses the power of forecasting, which enables you to find inventory from Google partners using criteria that are automatically detected instead of publisher declared (for example, content vertical classification, viewability, sizes, formats, and so forth).You can use the marketplace to find matching site and apps that are eligible for open auction or deals, then export them for media planning or find matching publishers to reach out to directly through their contact information or the request for proposal (RFP) workflow. Learn more about requesting a proposal for publisher inventory.

  1. Sign in to Authorized Buyers.

  2. Click Marketplace.
  3. From the left menu, select Discovery.

View statistics across all inventory

The forecast widget gives an estimate of the number of impressions and unique users expected across all inventory over a 7-day period based on recent history, as well as breakdowns into individual metrics (user gender, geo, device, and so forth). The bid landscape chart shows the bidding activity for the sold inventory matching your search criteria. As you adjust the filters along the right, the statistics will change as well.
