# Tutorial | Selecting ad placements to test-drive Demand Hub
## Demand Hub is most effective in contexts that feature engaging, interesting content capable of keeping visitors on for extended periods.
Demand Hub is an ad format that helps publishers maximize their inventory ECPM through engaging animated ad templates. To get the most out of Demand Hub, it's recommended to test it on ad placements that meet the following criteria:
- High-quality, long-form content that keeps users on the page for an extended period of time.
- Ad placements that have an exposition time of at least 15 seconds.
- Above-the-fold ad slots that have high visibility and engagement.
- Sticky mobile and desktop ad slots, which have been found to increase bid values by up to 30% compared to billboards.
By following these guidelines and testing Demand Hub on appropriate ad slots, you can increase the likelihood of greatly increasing your inventory ECPM through Demand Hub.
### Step 1. Select one domain to get started
(In case you manage multiple properties)
When selecting an initial domain to test Demand Hub, it's important to choose a property that allows it to work at its full potential so you can later take an informed decision to scale.
Demand Hub typically performs well on sites with content that is engaging, unique, and keeps visitors for a long period of time. Typically websites that contain quality, long-form content with high average time on page.
For example:
- News websites: news and stories in tech, events, politics, sports, entertainment, and other topics.
- Digital magazines: long-form articles (music, lifestyle,...).
- Review websites: editorially written reviews and ratings (tourism, tech, music gear,...)
- Educational websites: educational resources, such as online courses, tutorials, and quizzes.
- Blogs: regular content, often in the form of articles or posts
You should avoid :
- Sites relying heavily on user-generated content such as forums, classified ads, etc...
- Sites with low average session duration
- Sites receiving a large portion of traffic from outside of US, Canada, France, UK, Germany and Spain.
> Please note that Demand Hub may under-perform in geographies outside of the US, Canada, and Western Europe. It's recommended to filter out ad requests from those geographies to optimize the performance of Demand Hub.
### Step 2. Define an initial set of placements
As for the selection of the domain, we recommend that your initial selection of ad placements allows Demand Hub to work at its full potential so you can evaluate results properly and be able to make an informed decision to scale.
When selecting ad placements, it's recommended to opt for **anchor/sticky ad placements**, as well as **in-content** placements within long-form content that keep users engaged for an extended period of time. This type of placements tends to have a higher time in the user's viewport, and lead to better ad performance.
Demand Hub is **compatible with standard IAB sizes**. To get started with Demand Hub on your inventory, we recommend testing it on a variety of domains, devices, and formats.
> Here's an example of an initial setup:
> \- Mobile\_Sticky\_Bottom (320x50)
> \- Desktop\_Sticky\_Sidebar (300x600)
> \- Content\_2 (300x250)
For ad placement selection, we recommend opting for:
- ad placements that have an **exposition time of at least 10 seconds** (15 seconds recommended) to allow for animations within the ad template, leading to better bid values and monetization.
- ad placements within **long-form content** (articles, editorial reviews,...)
- ad placements with a **variety of sizes**
- a **mix of desktop and mobile** placements
- In case you have auto-refresh implemented, refresh rate shouldn't be inferior to 20 seconds for Demand Hub to drive satisfactory results.
Note that Demand Hub is not compatible with AMP placements
### Step 3. Implementation
Once you have selected an initial domain and ad placements, you can implement Demand Hub.See here for [Demand Hub integration guide](https://knowledge-base.optidigital.com/knowledge/how-can-opti-engage-be-integrated-into-my-ad-stack?hsLang=en)
> Before going live you should make sure that
>
> \- ad requests are only coming from the agreed-upon domains and geographies
> \- the ads.txt file is updated before sending bid requests to Demand Hub.
> \- you added "Opti Digital" in your Consent Management Platform
### Step 4. Monitor results
Once live, Demand Hub now takes part in Prebid auctions, competing against other bidders in your programmatic stack.
In your adserver analytics, Demand Hub will appear as 'optidigital' in your programmatic ad stack. Performance may take **2 to 5 days** for the initial ramp-up and **approximately 2 weeks** for it to reach its full potential We recommend checking your ad server analytics and the Opti Digital reporting dashboard daily during this period. Key metrics to monitor include eCPM, fill rate, and viewability.
We also provide daily reporting on Demand Hub performance.
Once you are satisfied with the integration and its performance, you can gradually scale it to the rest of your inventory. By doing so, you can potentially see even better results and maximize the benefits of using Demand Hub.
### Step 5. Scale-up
After evaluating Demand Hub's performance and confirming satisfactory results, you can scale it up gradually to additional placements and domains. Consider the following steps:
- Add Demand Hub to new high-quality ad placements that meet the criteria defined in Step 2.
- Expand to additional domains that match the site profile described in Step 1.
- Contact your Opti Digital account manager to discuss a tailored scale-up plan.
