Apart from the SEO related options that are available as part of a Story- Sections, Tags and Collections can all have SEO metadata associated with them.

For Sections

1. From the Admin menu, select SEO Metadata.
2. From the dropdown menu select the Section for which you want to specify SEO metadata.
3. Provide appropriate inputs in the page-title, meta-title, description, and keywords boxes.

For Collections

Collections inherit SEO metadata from the Stories that are included in a Collection. Collections also inherit metadata from the Sections that those stories are part of. You do not have to explicitly specify SEO metadata for Collections.
