Samsung DSP consists of connecting Buyers and Sellers.

On one hand, Buyers, i.e., advertisers, are looking for advertising space to broadcast their ad.

On the other hand, Sellers, i.e., publishers, are selling those spaces to generate revenue.

This document describes how to create a seller so that buyers can bid on their inventory for targeting.

Samsung DSP classifies sellers into 2 categories: AdGear and Non-AdGear. See the following links to create the seller based on the exchange you plan to use:

• Create a Seller for AdGear Exchange
• Create a Seller for Non-AdGear Exchange

Create a Seller for AdGear Exchange

1. Log in to Samsung DSP.
2. In the left pane, click on Admin Tools and select Sellers.
3. In the upper-right hand corner, click on +New Seller.
   
4. Enter the name of the seller (i.e., publisher).
5. Click on Select File to browse to the location where the logo is stored.
6. In the Exchange drop-down list, select AdGear. The following options become available:
   
   1. First Price: By default, all auctions are resolved as second-price auctions on AdGearX. However, it is possible to enable first-price for private marketplaces. This option has a direct impact on the stability of the private marketplace. This option is locked after the seller has been created.
   2. Enable Blacklist Filters: All incoming traffic is filtered against global IP and URL blacklists by default. However, the option allows you to bypass this filter for private marketplaces where fraudulent traffic isn't an issue. Disabling this filter may reduce the quality of incoming traffic from this seller on AdGearX.
   3. Data Providers Pixels: By default, third party cookie-matching pixels (e.g., Lotame) are piggybacked with every impression. Disabling this option will remove such pixels, at the cost of reduced cookie-matching for buyers leveraging these third-parties on the seller's inventory.

AdGear Exchange Settings

• Currency: Select the currency to be used for the auctions.
• Request CPM: Enter the recommended CPM or Floor price for this seller.
• Media Percent: Set the percentage of the revenue to deduct as Media fees.
• Media CPM: Set the amount that should be deducted as Media Fees for 1000 impressions.
