Yahoo Exchange Policies

Yahoo is committed to providing a transparent marketplace.

Fee Transparency

Yahoo does not charge any hidden fees or buy-side fees to buyers.

Buyers do not pay above their bid price.

Yahoo charges publishers a fee to make their inventory available through our marketplace.

Ad request transparency

Yahoo provides information on the following attributes in each bid request:

• Publisher ID
• Required video fields
• Placement and tag IDs
• Transparent floors (when consented to by the publisher)
• Transparent domains (when provided by the publisher)

Transparent change notification

Any material changes or modifications to the marketplace design that may alter performance for buyers are communicated in advance of going live within a reasonable timeframe.

Purposeful ad request duplication

We do not purposefully duplicate ad requests in our system, nor do we send ad requests for the same impression opportunity simultaneously with alternate floors EXCEPT for PMP/Deal ID opportunities that require different floors set for different priorities (outlined in Pre-Auction price floors section above).

We may send multiple ad requests for the same impression sequentially if the first request did not fill.

Non-purposeful ad request duplication

Header bidding supply often results in duplicate ad requests for the same ad impression opportunity across different Exchanges. Yahoo does not de-duplicate this supply, but complies with applicable industry standards (such as the inclusion and population of the transaction id [BidRequest.source.tid] or other mechanisms) to aid the decisioning for our buyers.

Location data modification

Yahoo does not make any material modifications to location data measurement between those values reported by the host device OS and those sent to the DSP.
