SmartSwitch optimises a Buyer’s BidStream by analyzing bid request parameters such as Country, Device, Native, and others. Using these parameters and overlaying the data on impressions that were won/bid on, SmartSwitch is able to detect a Buyer’s specific buying pattern and optimise the type of bidstream traffic it receives. For more information on the parameters used, see the SmartSwitch Fields section.
SmartSwitch also uses u-Predict models to estimate the probability of a bid request sent to a Buyer receiving a winning bid. To learn more, see the u-Predict site.
By combining the traffic that matches both criteria: desired traffic with higher win probability, a Buyer receives a much higher quality of traffic as defined by their own buying preferences.
SmartSwitch and QPS¶
Listening to the the full BidSwitch bidstream would overwhelm most Buyers and result in overloading a Buyer’s servers. As well as incurring increased costs just to be able to listen to more traffic, without SmartSwitch Buyers would also listen to a lot more random traffic thus reducing the quality.
The goal of SmartSwitch is to ensure that the best bids reach a Buyer within its QPS settings. For more information about QPS, see the QPS Overview and Controls section. Use the following table and charts to understand the benefits of SmartSwitch.
SmartSwitch Buyer Benefits¶
Random inventory is sent to the Buyer based on a subset of the total bidstream.
Optimised inventory is sent to the Buyer, which closely aligns with their buying pattern.
Lower relative levels of desired inventory available to the Buyer versus the amount of traffic to which it listens.
Increased levels of desired inventory sent to the Buyer within their listening capacity.
Lower bid/win ratio due to inventory not matching the Buyer’s bidding parameters as closely as possible.
Higher bid/win ratio because traffic matches the Buyer’s bidding strategy.
Lower Buyer ROI on servers and other infrastructure costs.
Better ROI due to increased efficiency of infrastructure usage.
Machine learning quickly responds to any changes in a Buyer’s buying pattern, and realigns bids sent to match the Buyers wishes.
Any new inventory will be immediately routed to a Buyer if considered optimal.
SmartSwitch BidStream Optimisation
SmartSwitch Supplier Benefits¶
Routes traffic to Buyers most interested in the inventory type you’re selling.
Increases the amount of interested Buyers potentially bidding on each impression, and with an increased number of bidders, theoretically a higher clearing price.
Screens all Bid Requests and returns a No Bid Reason should some traffic be flagged as potentially fraudulent, enabling Suppliers to clean up their network of possible bad actors, see the Supplier No Bid Reason section for more details.
QPS Overview and Controls¶
QPS (Queries Per second) in BidSwitch refers to the maximum absolute limit placed on traffic received from a Supplier or sent to a Buyer per data centre. Your total QPS volume is split between two traffic types.
Deals : for private deal traffic or other traffic sources that require special consideration to ensure they reach your trading partner.
Open Auction : normal RTB open auction traffic.
Each of these has its own QPS value which partitions your total volume, and each value can be adjusted to the Buyer’s requirements within the constraints of the overall QPS capacity.
To view or request an adjustment to your QPS settings, on the myBidSwitch UI go to thepage.
To request a new limit for either type of QPS, select Request New Limit for the relevant Data Centre.
The QPS settings do not set the actual amount of traffic that BidSwitch sends to a Buyer. It is the maximum traffic that a Buyer could receive, and BidSwitch will not send more than the maximum QPS value.
It is highly recommended that you set the maximum QPS value in accordance with the real capacity of your servers. Otherwise, if you start buying in large volumes, BidSwitch will start sending the maximum amount of QPS which could overload your servers.
For open auction traffic, Buyers receive two types of traffic from BidSwitch: targeted and learning traffic.
The learning traffic is sent to detect changes in buying preferences. If a Buyer starts buying more from a specific traffic segment, then BidSwitch sends more traffic from that segment. This also works vice-versa, if a Buyer stops buying from a particular traffic segment, BidSwitch sends less traffic of that type.
Influencing Traffic Volumes¶
The real influence on traffic volumes sent to a Buyer is the amount and type of traffic that the Buyer buys. The more traffic that a Buyer buys in a particular segment, the more of that traffic will be sent to focus bidding on what is desired.

Projections are extrapolated based on past data, and past performance is no guarantee of future performance.
SmartSwitch for Private Deals¶
SmartSwitch for Private Deals allows Buyers to filter their Deals Traffic using SmartSwitch. This feature works the same as when it filters Open Auction traffic.
Overall Private Deals QPS levels are set per Data Centre and can be found on thepage
Private deals are those with
pmp.private_auctionbid request field set to
1, see the Private Marketplace Object section for more details.
Open Auction and Private Deals QPS volumes can be controlled within a Targeting Group settings.
SmartSwitch for Private Deals can be turned OFF/ON within the same section.
SmartSwitch shapes the Private Deals traffic being sent to your bidder to align with your active buying preferences and it will fill the available QPS with the most actively bought inventory. Buyers are free to turn-off SmartSwitch For Deals within Targeting Groups, in such cases no filtering is applied to the traffic and any limitations are due to random cutoff when QPS limits are reached.
To configure Targeting Groups to use Private Deals QPS and SmartSwitch for Deals, open thesection for the specific targeting group you wish to edit.
If SmartSwitch for Private Deals is not enabled on your account, the UI will just present a greyed-out button. Please speak with your account manager to have it enabled on your account.
