Please notice that this is a "Web-only" feature We recommend that you talk to the different Bidders and ask how they prefer the DPO to work, and if it is to be activated at all; as some of them prefer to get 100% of the traffic, and then do the optimisation on their end, towards the Exchanges and DSPs. ### DPO Control on different levels: If you would like to limit the traffic for one or more of your bidders, you can do so on several levels in the system: * Global * Publisher * Website * Placement And it is all handled through the "Prebid parameters" on one of these levels: ![2025-03-18 15\_25\_24-Account settings](/files/72fbdc50b730db164610dfc35807d302c26e6948) In the **Generic Prebid Config Data >** **Demand Path Optimization > Enable**, you will find the options to set criteria for when to call and not to call a particular Bidder/SSP. ![](/files/b399f00c5221fa0848d2d53ddd42cc1fe01980cb) #### Performance Filter Additinal filter can be applied based on Fill Rate and Ad Unit eCPM. You can configure to check per country if preferred. ![](/files/feccc531a51229de062d8aaafed5af42252869e2) One of the most common criteria is to block out specific countries (or include specific countries if the Bidder is more regional). ### Include/Exclude traffic based on GEO Here you can set Include/Exclude traffic from specific countries: ![](/files/5870b18e7bb2ccb02be2f75995757e11c715ae1f) ### How do I know which countries to block for a particular Bidder? A good starting point for evaluating DPO, is to pull a report based on Bidder - per country, and then one of the metrics you find important. One of these could be **Revenue**, if you are interested in only having the Bidders that brings the most value for each geo, but you could also think about things like **Adunit eCPM** (how well the traffic is monetised), or maybe even **fill rate %** - as some GEOs might have low value bids, but maybe of them. Breaking down a report makes it possible to see which countries are performing for each bidder, and then make your decision based on that. > Please notice this might effect your revenue negatively, as you potentially allow less traffic to be bought; but less calls should lower the impact on the environment. ## Related articles * [Edit Bidder settings | Pass schain node or First party data to bidders](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/15ffabb77b540c7069ce428c6445ca7e060a6aef) * [How to Activate/Deactivate Prebid/Header bidding on specific placements (Only for web)](/hb-manager/auction-behavior-and-optimization/how-to-activate-deactivate-prebid-header-bidding-on-specific-placements-only-for-web.md) * [Customizing Bidder Logos](/hb-manager/setup/customizing-bidder-logos.md) * [Adding Amazon UAM/TAM to your Prebid setup](/hb-manager/integrations-and-connections/adding-amazon-uam-tam-to-your-prebid-setup.md) * [Mapping Adserver and SSP placement IDs to Relevant Yield Placements](/hb-manager/setup/mapping-adserver-and-ssp-placement-ids-to-relevant-yield-placements.md) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.relevant-digital.com/hb-manager/auction-behavior-and-optimization/bidder-specific-demand-path-optimisation-dpo-setup.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
