On your publication's homepage, you can use links as a blogroll, to direct readers to other places to find you on the web, or to highlight popular posts, among other uses.
To add a link to your Substack's homepage, go to your publication's Settings page and click on "Edit" next to "Homepage links".
You can title and add any link you wish, including your own Substack or other publications you own.
When assigning a group, think of this as a category or genre by which to organize your homepage links.
Tip: You can edit your homepage links section by deleting a link and adding another.
