About This 4-Part Automation Series

As a media buyer, I built this system to automate the heavy lifting of analyzing ad data and brainstorming new creative ideas. This template is the first foundational part of that larger system.

✅ Part 1 (This Template): Pulling Ad Data & Getting Quick Insights Automatically pulls data into a Google Sheet and uses an LLM to categorize ad performance.

✅ Part 2: Finding the Source Files for the Best Ads Fetches the image or video files for top-performing ads.

✅ Part 3: Using AI to Understand Why an Ad Works Sends your best ads to Google Gemini for structured notes on hooks, transcripts, and visuals.

✅ Part 4: Getting the AI to Suggest New Creative Ideas Uses all the insights to generate fresh ad concepts, scripts, and creative briefs.

What This Template (Part 1) Does

Secure Token Management Automatically retrieves and refreshes your Facebook long-term access token.

Fetch Ad Data Pulls the last 28 days of ad-level performance data from your Facebook Ads account.

Process & Clean Parses raw data, standardizes key e-commerce metrics (like ROAS), and filters for sales-focused campaigns.

Benchmark Calculation Aggregates all data to create an overall performance benchmark (e.g., average Cost Per Purchase).

AI Analysis A “Senior Media Buyer” AI persona evaluates each ad against the benchmark and categorizes it as “HELL YES,” “YES,” or “MAYBE,” with justifications.

Output to Google Sheets Updates your Google Sheet with both raw performance data and AI-generated insights.

How to Set It Up

Credentials

Connect your Google Gemini and Google Sheets accounts in the respective nodes.

The template uses NocoDB for token management. Configure the “Getting Long-Term Token” and “Updating Token” nodes — or replace them with your preferred credential storage method.

Update Your IDs

In the “Getting Data For the Past 28 Days…” HTTP Request node, replace act_XXXXXX in the URL with your Facebook Ad Account ID.

In both Google Sheets nodes (“Sending Raw Data…” and “Updating Ad Insights…”), update the Document ID with your target Google Sheet’s ID.
