How does native work?

Unlike standard display ads, native ads are assembled using an image, headline, description, and brand logo. They are created to match the unique look and feel of each publisher. The look and feel of the ads vary across publishers, and not all publishers include all the aforementioned ad components; for example, some exclude the logo or description.

You can be more specific about which native format you want to traffic, with the options being InFeed or All Native Formats (including InFeed).
