[Q&A](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#qa) # How does Demand Hub work? ## Demand Hub is able to gather and process multiple demand sources in real-time, in order to increase monetization opportunities for the publisher. Besides a cutting-edge user experience with engaging banner templates, Demand Hub uniqueness relies on the **aggregation and transformation of multiple demand sources** in real-time, increasing monetization opportunities for the publisher. This is how it works: for each impression request received from the publisher's website, Demand Hub fetches **user IDs** and creates an **auction** that contains **multiple sub-impressions** based on the estimated exposition time in the specific context (publisher, page and ad unit). Those sub-impressions correspond to the different **"slides''** in the dynamic banner template.  Demand Hub then processes **Bid responses** from top demand sources, and winners with the highest bid values, increasing the competitiveness of the auction and ultimately leading to higher monetization for the publisher. Furthermore, Demand Hub is able to **transform sizes and demand formats** (native, video and display) in real-time to match the **ad unit target format**, increasing the chances that the ad will be displayed and ultimately a high fill rate. This feature is unique on the market as of today. This is **a powerful solution for premium sites** that rely on high-quality content and high average time on page, where users spend a lot of time reading and engaging with the content.   Get [more information about Demand Hub and check the demo](https://www.optidigital.com/en/opti-engage/) - [Ad Manager Hub](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#main-content) - [Overview](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#overview) - [Getting Started & Onboarding](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#getting-started-onboarding) - [Advanced Tag Capabilities](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#advanced-tag-capabilities) - [Ad Formats & Experiences](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#ad-formats-experiences) - [Demand & Header Bidding](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#demand-header-bidding) - [Yield & Pricing Optimization](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#yield-pricing-optimization) - [A/B Testing & Optimization](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#a-b-testing-optimization) - [Insights & Analytics](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#insights-analytics) - [Audience & Targeting](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#audience-targeting) - [FAQs](https://knowledge-base.optidigital.com/knowledge/ad-manager-hub?hsLang=en#faqs) - [Demand Hub](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#main-content) - [Overview](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#overview) - [Getting Started & Onboarding](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#getting-started-onboarding) - [User Experience](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#user-experience) - [Invoicing and payments](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#invoicing-and-payments) - [Q&A](https://knowledge-base.optidigital.com/knowledge/demand-hub?hsLang=en#qa) - [Insights Hub](https://knowledge-base.optidigital.com/knowledge/insights-hub?hsLang=en#main-content) - [Overview](https://knowledge-base.optidigital.com/knowledge/insights-hub?hsLang=en#overview) - [Getting Started & Onboarding](https://knowledge-base.optidigital.com/knowledge/insights-hub?hsLang=en#getting-started-onboarding) - [Pre-Built Analytics Dashboards](https://knowledge-base.optidigital.com/knowledge/insights-hub?hsLang=en#pre-built-analytics-dashboards) - [Custom Reporting](https://knowledge-base.optidigital.com/knowledge/insights-hub?hsLang=en#custom-reporting) - [Ad Experience Hub](https://knowledge-base.optidigital.com/knowledge/ad-experience-hub?hsLang=en#main-content) - [Overview](https://knowledge-base.optidigital.com/knowledge/ad-experience-hub?hsLang=en#overview) - [Getting Started & On Boarding](https://knowledge-base.optidigital.com/knowledge/ad-experience-hub?hsLang=en#getting-started-on-boarding) - [Ad Formats & Experiences](https://knowledge-base.optidigital.com/knowledge/ad-experience-hub?hsLang=en#ad-formats-experiences) - [Yield Hub](https://knowledge-base.optidigital.com/knowledge/yield-hub?hsLang=en#main-content) - [Overview](https://knowledge-base.optidigital.com/knowledge/yield-hub?hsLang=en#overview) - [Getting Started & Onboarding](https://knowledge-base.optidigital.com/knowledge/yield-hub?hsLang=en#getting-started-onboarding) - [FAQ](https://knowledge-base.optidigital.com/knowledge/yield-hub?hsLang=en#faq) - [Release Notes](https://knowledge-base.optidigital.com/knowledge/release-notes?hsLang=en#main-content) - [2026](https://knowledge-base.optidigital.com/knowledge/release-notes?hsLang=en#2026) [![Chill listening crop-3](https://knowledge-base.optidigital.com/hs-fs/hubfs/Logo%20-%20BG%20White%20(1).png?width=64&height=24&name=Logo%20-%20BG%20White%20(1).png "Chill listening crop-3")](https://www.optidigital.com) Help Center Copyright © 2026, Opti Digital
