# How to Research Competitor Ad Creatives with ChatGPT

ChatGPT discovers competitor ads and presents them with strategic analysis. It categorizes creatives by format, messaging theme, and platform, explains why certain ad approaches likely perform well, and can generate creative brief suggestions inspired by the most effective competitor ads for your marketing team.

## Setup

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

## Steps

1. Add ToolRouter to ChatGPT using the MCP JSON configuration
2. Start a conversation: "Find all ads that competitor.com is running on Facebook and Google"
3. ChatGPT uses ToolRouter's Ad Library Search to fetch and present the ad creatives
4. Request analysis: "What are the top themes and calls to action in these ads?"
5. Ask for recommendations on how to differentiate your own ads

## Example Prompt

```
Search for ads by Mailchimp on Facebook and Google. What messaging do they use most? How can I differentiate?
```

## Tips

- ChatGPT is great at summarizing messaging themes across large ad sets
- Ask it to categorize ads by funnel stage: awareness, consideration, conversion
- Use the analysis to brief your creative team on competitor positioning
