What is Zoom?
ZoomBot generates link previews when URLs are shared in Zoom Chat during meetings or in persistent chat channels. As remote work and virtual meetings have become standard, Zoom's chat functionality has grown in importance for sharing resources and collaboration. The bot extracts metadata to create previews that help meeting participants quickly understand shared content without leaving the Zoom interface. This functionality enhances collaboration by providing context for shared links directly within the communication platform.

How to Control Zoom
Block Completely
To prevent Zoom from accessing your entire website, add this to your robots.txt file:
# Block Zoom
User-agent: ZoomBot
Disallow: /

To restrict access to certain parts of your site while allowing others:
User-agent: ZoomBot
Disallow: /admin/
Disallow: /private/
Disallow: /wp-admin/
Allow: /public/
Set Crawl Delay
To slow down the crawl rate (note: not all bots respect this directive):
User-agent: ZoomBot
Crawl-delay: 10
