# How to Find Successful Ad Formats with ChatGPT

ChatGPT identifies successful ad formats and provides creative strategy recommendations. It analyzes which formats — video, carousel, static image, collection — dominate in your category, explains the likely performance drivers, and can generate creative specifications for each format tailored to your brand and objectives.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Search Facebook ads for 'SaaS tools' and tell me which ad formats appear most"
3. ChatGPT presents a breakdown of formats with examples
4. Request: "Get all ads from Notion on Facebook and analyze their format strategy"
5. Ask for recommendations on which formats to prioritize for your own campaigns

## Example Prompt

```
Find Facebook ads for "SaaS tools". Which ad formats are most popular? Then analyze Notion's specific ad format mix.
```

## Tips

- ChatGPT provides clear format breakdowns that are easy to share with creative teams
- Ask for pros and cons of each format for your specific use case
- Request creative briefs for the top-performing formats identified
