For Publishers

By knowing how feeds are parsed and following a few guidelines you can make your content shine for users.

Feed Metadata

The title and images included in the RSS, Atom, or JSON source is preferred. The application will periodically check the feed homepage to attempt to fill in gaps. For example, if an appropriate banner image is not found in the feed, it will look for a social image on the homepage to use instead.

Images

The application looks for images first in feed entry metadata then entry description/summary content.

In any case, providing an accurate image width and height will greatly improve how images are displayed in the application. When width and height is provided images will be displayed at the maximum possible size. Otherwise, images are constrained to a 16:9 frame.

Description/Summary Content

Summary content is limited to a subset of HTML and style attributes are filtered.
