# Ad Locations _Boost your ad revenue by setting up Ad Locations for Chartboost on your mediation solutions._ ## Before You Begin For interstitial and rewarded placement types, Chartboost supports flat CPM. - Flat CPM means Chartboost guarantees to pay the exact amount of the specified CPM price, nothing more or less. For example, if you set up a $10 flat CPM for the interstitial inventory of your app in the US, Chartboost will pay $10 CPM. For banner placement type, Chartboost supports CPM floor. - CPM Floor means Chartboost guarantees to pay no less than the specified CPM price. For example, if you set up a $2 CPM floor for the banner inventory of your app in the US, Chartboost might pay $2.50 CPM, but not under $2 CPM. In addition to using the Chartboost platform to create and edit Ad Locations, you can also use the new Chartboost Publisher CPM Management API to achieve the same goal. If you are interested, please reach out to your Chartboost account manager or . ## Overview of Ad Locations From the navigation menu, go to **Monetization > Apps** and you will see an overview of all existing apps that have ad location setup (including those set up by your account manager at Chartboost). - This overview will provide the total number of ad locations, earnings, requests, impressions, and show rate for each app. - You can also filter by the specific app store. To edit the Ad locations and format type, click on the app you wish to make changes to. ## Create a New Ad Location You can add up to 100 unique location names per app and location type. 1. On your **Monetization > Apps** overview page, or within any app, click **+ Create new Ad Location**. 2. Select the **app** from the dropdown menu. 3. Select the **ad format** for this ad location (Interstitial, Rewarded, or Banner). 4. Create an **ad location name** for this ad location that helps you quickly identify it. 5. Select an **ad location type** (Fixed CPM or Bidding). 6. For **Fixed CPM**, set a **CPM rate** and select the **countries** to apply this CPM. 7. Click **Create** to complete. Please note the restrictions and permitted characters for the naming of ad locations. All ad location names are case-sensitive. - Maximum of 80 characters - Upper or lower case - Numbers 0-9 - Special characters allowed: $ & - _ , + / \ - Spaces are not allowed ## Ad Location Type ### Fixed CPM You can set up different countries with different flat CPM prices for the same location name. However, you can not set up different flat CPM prices for the same location name and the same country. For any countries not set up with flat CPM or CPM floor prices, Chartboost will automatically optimize for the publisher's best yield. - For example, you filled in Interstitial Location One, only selected the United States (no other countries selected), and specified a $20 flat CPM. In this case, if Chartboost receives ad requests from Interstitial Location One in Canada, Chartboost will match the best ads possible and serve dynamic eCPM, which is not guaranteed to be at $20 CPM. ### Bidding The **Bidding** ad location type is for publishers who wish to bid into the Chartboost Exchange using In-App Bidding, Chartboost’s Real Time Bidding solution.
