[Bookings](https://site.passendo.com/passendo-ad-server?hsLang=en#bookings) # Priority Level This setting determines the delivery priority of bookings, where *10* represents the highest priority and *80* the lowest. The system selects and serves bookings on a placement based on these priority levels, starting with bookings assigned priority *10*, then *20*, *30*, and so on. If two bookings target the same placement, one with priority *10* and the other with priority *50* (let's say), Passendo will first attempt to serve the higher-priority campaign (in this case, the one with priority *10*), provided that its budget, impression cap per user, and targeting conditions allow. A lower-priority booking (such as the one with priority *50*) will only be considered afterward, even if its *force switch* is toggled to "yes." Activating the *force switch* means that the booking will attempt mandatory delivery on all eligible impressions, subject to its set budget, priority level, and targeting constraints. However, priority remains the dominant rule; being "forced" does not override it. The system continues to select and serve bookings by priority level first: *10*, then *20*, *30*, and so forth. When multiple bookings across different campaigns share the same priority level, the system uses the *eCPM* value to determine which booking is served first. Pacing, frequency capping, geolocation targeting, and other campaign parameters may also influence that decision. That said, if more campaigns have the same priority and only one of them is "forced," the forced campaign will be shown on all impressions, as long as delivery constraints (budget, targeting, etc.) permit. Depending on the publisher’s ad-serving strategy, multiple priority levels may be used simultaneously, each reserved for a specific purpose. **Example Setup:** - **10** – Reserved for *sponsorship* (SOV) campaigns. This highest-priority tier is used for exclusive placements, ensuring ads are first served in eligible impressions. - **20–30** –These are used for *direct-sold* campaigns, either on CPC or CPM basis. These bookings can auto-optimize based on eCPM. - **40–60** – Allocated to demand coming from the *Passendo Exchange*. Notably, **priority 50** serves as a balance point, ideal for campaigns optimized by Passendo’s algorithm for performance (e.g., revenue or CTR). - **70** – Typically used for *house* campaigns, potentially optimized on eCPM or at least on targeting and frequency controls. - **80** – Reserved for *1x1 fallback* placements. - [Emperor](https://site.passendo.com/emperor?hsLang=en#main-content) - [Account configuration](https://site.passendo.com/emperor?hsLang=en#account-configuration) - [Managing your inventory (SUPPLY)](https://site.passendo.com/emperor?hsLang=en#managing-your-inventory-supply) - [Managing your ads (DEMAND)](https://site.passendo.com/emperor?hsLang=en#managing-your-ads-demand) - [Reporting](https://site.passendo.com/emperor?hsLang=en#reporting) - [Passendo Ad Server](https://site.passendo.com/passendo-ad-server?hsLang=en#main-content) - [Onboarding your media](https://site.passendo.com/passendo-ad-server?hsLang=en#onboarding-your-media) - [Exchange](https://site.passendo.com/passendo-ad-server?hsLang=en#exchange) - [Quick guides](https://site.passendo.com/passendo-ad-server?hsLang=en#quick-guides) - [Bookings](https://site.passendo.com/passendo-ad-server?hsLang=en#bookings) - [Campaigns](https://site.passendo.com/passendo-ad-server?hsLang=en#campaigns) - [Creatives](https://site.passendo.com/passendo-ad-server?hsLang=en#creatives) - [Advertisers](https://site.passendo.com/passendo-ad-server?hsLang=en#advertisers) - [Default HubSpot Blog](https://site.passendo.com/blog) [![passendo logo](https://site.passendo.com/hs-fs/hubfs/Passendo_Primary_Logo-1.png?width=568&height=110&name=Passendo_Primary_Logo-1.png "passendo logo")](http://www.passendo.com) Passendo Help Center Copyright © 2026, Passendo
