Facebook ad library analyzer with AI summaries

Description

For automation builders and agency owners,

Your competitors’ best Facebook ads, analyzed weekly, automatically.

This is a production-ready n8n workflow that collects Facebook Ads Library ads, analyzes them with AI, and delivers a clean competitor-intelligence database to Google Sheets with no manual work.

Set it once. Let it run every week.

What this workflow does

• Scrapes Facebook Ad Library for a chosen keyword or niche
• Filters out low-signal advertisers automatically
• Analyzes video, image, and text ads using the correct AI model
• Produces structured summaries and rewritten copy
• Writes everything into Google Sheets

You get a growing database of competitor ads that your clients can actually use.

---

Why this matters

Manual ad research takes hours and rarely happens consistently.

Most tools ignore video ads entirely, even though that is where the biggest budgets and strongest hooks are.

Raw scraped data is not client-ready and requires manual cleanup.

This workflow removes all of that.

How the intelligence works

Video ads

• Downloads each video
• Uploads using a resumable Gemini flow that works in n8n
• Extracts hooks, narration, pacing, CTAs, and on-screen text

Image ads

• Sends the image directly to GPT-4o Vision
• Breaks down layout, visuals, hierarchy, and CTA placement

Text ads

• Analyzes messaging angle, offer, and positioning
• Produces structured summaries and rewritten ad copy

All formats are unified into one Google Sheet.

Final note

Ad Library data disappears when ads stop running.

The earlier you start collecting, the more valuable your dataset becomes over time.
