# How to Discover Duplicate Content with Copilot

Copilot detects duplicate content issues and connects them to the templates, routing rules, or CMS configurations in your codebase that cause them. Fix canonical tags, add URL parameter handling, or adjust routing logic directly in your editor to resolve duplication at the source rather than page by page.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. Ask: "Crawl mysite.com and detect duplicate content"
3. Review duplicate page groups and their URLs
4. Ask Copilot to add canonical tags or redirect rules in your code
5. Re-crawl to verify duplicates are properly resolved

## Example Prompt

```
Find duplicate content on mysite.com and add canonical tags to my page templates to resolve them.
```

## Tips

- Copilot can add canonical link elements to your layout components
- Great for fixing URL parameter-generated duplicates with route normalization
- Check your dynamic routes for patterns that create unintended duplicate pages
