Buying Native Inventory

Native ads seamlessly integrate advertising into a placement's context. In contrast with traditional HTML/JavaScript ads, native ads specify the ad content but not how to display it. This lets publishers control their user's experience by integrating advertising within their inventory, and it affords advertisers higher quality inventory to choose from.

Xandr provides access to a number of native supply sources. While you can set up individual profiles for each source, we recommend that you set up a single profile to reach all of them simultaneously. This type of setup allows for easier budgeting, reporting, performance-tracking, frequency capping, etc. This page describes the process of setting up a profile to serve across whichever native sellers you choose.

For specific information on individual sellers, see Native Inventory Seller Specifications.
