Why should I add topics?

Reddit uses community topics to surface your community and content to the right users (and not to less relevant users).

Example, Reddit may recommend your community to users who have shown interest in the community topics you’ve added.

What is a primary topic, why do I have to select a primary topic?

Think of the primary topic as a highest level general category for your community. You can add up to 24 additional subtopics (including free form) once you’ve added a primary.

Why can’t I write my own primary topics?

What primary topic should I pick if none of them fit for my community?

“None of these topics”
