Blocking Methods

1robots.txt

High for cooperative crawlers

Add a Disallow rule for Gemini-Deep-Research's user-agent string in your robots.txt file. This is the standard, cooperative method that well-behaved crawlers respect.

2Server-side UA filtering

High

Configure your web server (nginx, Apache, Cloudflare) to reject requests matching Gemini-Deep-Research's user-agent patterns. This blocks at the network level before your application processes the request.

3Switch Journey Workflows

Highest — granular, real-time control

Create a custom journey in Switch that detects Gemini-Deep-Research and routes it to a block action, challenge, redirect, or modified content — without touching your server configuration.
