AI Facebook Ad Spy Tool Explained: Automate Ad Analysis

Introduction

The AI Facebook Ad Spy Tool is a powerful automated workflow built in n8n that scrapes, analyzes, and archives Facebook ads for competitive intelligence. This tool leverages Facebook’s Ad Library API, advanced AI models (like Google Gemini and OpenAI GPT-4), and Google Sheets for storage to deliver comprehensive insights about active advertisements. If you’re running an ad agency or conducting market research, this workflow can streamline how you gather, analyze, and repurpose ad strategies from competitors.

How the Workflow Works

1. Execution Trigger

The process starts when you manually execute the workflow. This triggers a sequence that first scrapes Facebook Ads through the Run Ad Library Scraper node.

2. Scraping Facebook Ads

The scraper utilizes the Facebook Ads Library API to retrieve active ads based on specific search keywords, period filters, and media types. In the example setup, it scans for ads containing the exact phrase “ai automation” in the US within the last 7 days, fetching up to 200 ads including their active statuses and detailed ad info.

3. Filtering Popular Ads

After scraping, ads are filtered by the Filter For Likes node, which only passes ads from pages with over 1000 likes. This filter ensures you analyze ads from more credible or established advertisers.

4. Categorizing Ads by Content Type

The filtered ads are sent through a Switch node, categorizing them into three main types: Video Ads, Image Ads, and Text Ads. Each category follows a tailored analysis workflow optimized for its media type.

5. Video Ads Processing

1. Video URLs are downloaded locally using the Download Video node.
2. Videos are uploaded to Google Drive for easy accessibility.
3. A Gemini API upload session is initiated, then the video is redownloaded and uploaded to the Gemini AI platform.
4. After a brief wait, Gemini analyzes the video and generates detailed descriptions.
5. The workflow sends the video metadata along with the generated description to OpenAI’s GPT-4.1 language model for a comprehensive summary and ad copy rewrite focused on strategic intelligence.
6. The enriched data is appended to a Google Sheet to build your ad intel database.
7. The workflow includes waiting nodes to handle API rate limits and ensure smooth processing.

6. Image Ads Processing

1. Images are analyzed by GPT-4o for extremely comprehensive object and context recognition.
2. Along with the original ad details, the GPT output is sent through GPT-4.1 to summarize and rewrite the ad copy.
3. The final output is stored to Google Sheets.
4. Waiting nodes handle pacing between API calls.

7. Text Ads Processing

1. Text ads are directly sent to GPT-4.1 for summary and rewriting.
2. Results are saved to the Google Sheet database.
3. Includes wait times to avoid rate limiting.

Customizing the Workflow

• Filter Thresholds: Adjust the minimum likes threshold in the “Filter For Likes” node to control which ads pass the filter.
