# How to Build Audience Segments with Claude

Claude builds personas through an iterative dialogue in your terminal that produces nuanced, specific results. Start with your product and market context, then refine each persona through follow-up questions that sharpen demographics, pain points, behavioral patterns, and buying triggers. The conversational depth means you can challenge assumptions, explore edge cases, and push beyond generic templates until each persona feels like a real person your team can design for, not a placeholder demographic summary.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Build audience segments for [your product] using persona-generator"
3. Claude generates distinct segments with demographics, interests, and messaging angles
4. Ask Claude to prioritize segments by estimated market size and conversion likelihood

## Example Prompt

```
Build 4 distinct audience segments for our online fitness coaching platform. Include targeting parameters I can use directly in Meta Ads and Google Ads.
```

## Tips

- Specify your ad platforms so segments include platform-specific targeting suggestions
- Ask for negative audience definitions too -- knowing who to exclude saves budget
