Build a Creative Diagnosis Engine for Meta Ads

Meta ads can be a complex challenge to navigate when it comes to ad creatives. If you run a Meta ad account, or are involved in performance marketing, you may find yourself constantly wondering: What is working, and why? What creative could be tested next? It is easy to get lost in the sea of data, taking more actions than necessary, and making decisions based on hunches. Fortunately, you can build an AI agent that reads your live Meta ad account, looks at every creative the way a human would, works out why each ad won or lost, and hands you a ranked plan of what to test. I call it a "creative autopsy agent".

Why This Matters

Advantage+ has made targeting and bidding easier, but the creative aspect is the only lever you still fully control. This means your main problem isn’t making more ads—it’s knowing which ad to make next. The goal is to figure out what creatives are working and why, and then to get the right metrics from your creative diagnostics to figure out what you should do next. The creative autopsy agent can help with this process.

The Creative Autopsy Agent

The creative autopsy agent is designed to scan your Meta Ads account and pull out a report of the last 30 days. This allows you to figure out why some creatives are winning while others are losing. This agent uses Claude Code to conduct a quick competition scan and research, providing a clear plan of action.

Here are the steps the agent follows:

1. Access and Data Collection: The agent first asks for the right Meta Ads account access and pulls the performance of your last 30 days' campaigns. This step ensures that the agent has a comprehensive understanding of your ad performance over the past month.

2. Fingerprinting: The agent then fingerprints your creatives, assessing the hook, format, opener shot, and offer. This logic is based on the premise that the success or failure of a creative on Meta depends on these four parameters. The agent scans your creatives on these parameters to identify what is working and what is not.

3. Competitor Analysis: If the agent identifies that you are not exploring fresh angles in your ads, it conducts a quick competition research through the Meta Ads Library. This step provides you with fresh angles that you can test, ensuring that your account never goes stale.

4. Actionable Insights: The agent then tells you what you need to exploit in your ad creatives, what you need to iterate, and what you need to fix. It also submits a report in the form of an Excel sheet, breaking down the performance into categories: exploit, iterate, and explore.

Key Points of Action

1. Data Access: The agent accesses 30 days of data from your Meta Ads account to analyze performance.

2. Diagnosis and Concentration: It diagnoses the performance of your creatives, concentrating on the hook, format, opener, and offer.

3. Competitor Research: The agent performs competitor research to identify new angles and opportunities.

4. Briefing and Operationalization: It provides a clear plan of action based on the analysis, helping you to operationalize your ad strategy.

Practical Example

In a demo, the agent identified that a competitor website, Carrot Lane, was winning because of brand authority and a modest percentage of something else. The agent also highlighted heritage players and provided insights into the angles you need to explore. This kind of detailed analysis can help you stay ahead of the competition and make more informed decisions about your ad creatives.

Main discussion

Why Metrics Matter

Metrics are crucial in understanding the performance of your ad creatives. However, metrics alone are not enough. You need to dive deeper into the creative aspects to understand why certain ads are winning or losing. The creative autopsy agent looks at the creative itself, not just the numbers, to provide a more comprehensive understanding.

Creative Diagnostics

The creative autopsy agent doesn’t just provide a list of winning and losing ads. It digs deeper to identify why certain ads are performing the way they are. For instance, it checks whether your ad account is dominated by a particular hook, format, openness, or shorter offer. If so, it suggests changes to avoid stagnation.

Iteration and Exploration

The agent breaks down the performance into three categories: exploit, iterate, and explore. This means it tells you what is working well and what needs improvement. It also suggests brand new angles to test, ensuring that your ad strategy never goes stale. This structured approach helps you to make more informed decisions about your ad creatives.

Scheduling and Tracking

The agent can be scheduled to run at regular intervals, ensuring that you always have up-to-date insights into your ad performance. It also allows you to save the information in the form of a tracker on Notion, Google Sheets, or Excel, making it easier to keep track of your ad performance over time.
