Advertisers can currently select article, mobile app, or video as their content type when creating or editing a piece of content within a boost.
Article: This default content type indicates that the landing page of the content is in article form. If the LP does not direct to a video or an app, article should be selected.
Video: If the landing page brings users to a video, video should be selected as the content type. If a publisher has enabled video content on their site, the campaign will appear with a play button. If a publisher has not enabled video content, the campaign will still show, but will not be accompanied by the play button.
Mobile App: This content type should be selected for all mobile apps.
