What is a key reason to cross-promote a Discord server on other platforms?

A key reason to cross-promote a Discord server on other platforms is to expand its reach and attract new members who may not be active on Discord itself. Cross-promotion involves promoting the Discord server on platforms where the target audience is already present, such as social media sites, websites, email newsletters, and online forums. By advertising the server's existence and benefits on these external platforms, you can tap into new pools of potential members who are interested in the server's topic but unaware of its existence on Discord. For example, a gaming community might cross-promote its Discord server on its YouTube channel or Twitch stream, inviting viewers to join the server for more interactive discussions and community events. This broader reach can significantly accelerate server growth and build a more diverse and engaged community.
