# How to Map Keywords to Clusters with ChatGPT

ChatGPT organizes keywords into semantic clusters and explains the topical authority strategy behind each grouping. It suggests pillar and cluster content structures, recommends internal linking patterns, and can generate a visual content hub plan that shows how individual pieces connect to build comprehensive topic coverage.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Group my keyword list into topic clusters"
3. ChatGPT organizes keywords into semantically related groups
4. Request: "Design a pillar page and supporting content plan for each cluster"
5. Get a complete content architecture with page hierarchies and linking plans

## Example Prompt

```
Cluster these 50 keywords about "project management" into topics. Create a pillar-and-cluster content plan for each group.
```

## Tips

- ChatGPT presents clusters in a clear format that is easy to share with content teams
- Ask for content briefs for the pillar page of each cluster
- Request URL structure recommendations based on the cluster hierarchy
