Analyze Meta ads with Gemini and Google Sheets

Stop manually exporting CSVs and start automating your marketing insights.

This workflow is designed for Marketing Agencies, Freelancers, and Media Buyers who want to keep a daily pulse on their Meta (Facebook/Instagram) Ads performance without logging into Ads Manager.

It doesn't just scrape data; it uses Google Gemini AI to act as a virtual data analyst. It reviews your campaigns, identifies winning/losing creatives, and writes strategic suggestions for both your agency team and your clients.

🚀 What this workflow does

1. Extracts Data: Wakes up every morning (6:00 AM) to fetch yesterday's Ad and Campaign performance from the Facebook Graph API.
2. Cleans & Filters: Automatically ignores paused or zero-spend campaigns to keep your reports clean.
3. Structuring: Uses a Code node to group Ads intelligently under their respective Ad Sets and Campaigns.
4. AI Analysis: Sends the structured data to Google Gemini. The AI analyzes CTR, CPC, and Spend to identify the "Best Performing Ad" and "Worst Performing Ad" per Ad Set.
5. Reporting:
   • Saves raw Campaign Data to Google Sheets.
   • Saves raw Ad Data to Google Sheets.
   • Saves AI-Generated Insights (Client & Agency suggestions) to a dedicated sheet.
6. Error Handling: If anything breaks (e.g., API token expiry), it instantly sends you an alert via Gmail with the error details.

💡 Key Features

• Zero-Spend Filter: Keeps your spreadsheet tidy by excluding inactive ads.
• Hierarchical Data Processing: Groups data logically so the AI understands the context of your tests.
• Dual-Perspective Insights: The AI generates two types of advice:
  • For the Client: Simple, performance-based updates.
  • For the Agency: Technical optimization tips (e.g., "Pause Ad B, Scale Ad A").
• Robust Error Monitoring: Includes a dedicated error workflow to notify you of failures.

🛠️ Prerequisites

• Meta/Facebook Developer App: A System User Access Token with ads_read permission.
