description

Provides expert-level analysis and diagnosis for Meta Ads campaigns. Use this skill to interpret performance data, identify root causes of issues, and generate actionable recommendations, with a special focus on correctly handling the 'Breakdown Effect'. Use when the user mentions Meta Ads analysis, campaign diagnosis, ad performance, CPA analysis, ROAS analysis, or asks to analyze exported data from Meta Ads Manager.

Meta Ads Analysis & Diagnosis Skill

When to Use This Skill

Use this skill when you need to analyze and diagnose Meta Ads campaign performance, including:

• Interpreting campaign, ad set, or ad-level performance data
• Identifying root causes of performance issues
• Generating actionable optimization recommendations
• Understanding why Meta's system makes certain budget allocation decisions
• Analyzing CSV exports, screenshots, or raw data from Meta Ads Manager

Result Recommendations (MANDATORY for Final Reports)

IMPORTANT: The following rules are MANDATORY and MUST be strictly followed when writing the final analysis report. These are not optional guidelines — they define the required standards for all deliverables.

• NEVER recommend pausing or reducing budget for any segment based solely on higher average CPA/CPM in breakdown reports. Higher average cost does NOT mean poor performance — it often reflects the system capturing low marginal cost opportunities earlier. Removing segments may increase overall costs. Always frame changes as testable hypotheses, not directives.
• ALWAYS justify recommendations with data evidence, Meta's system mechanics, and expected impact on overall campaign performance.
• EVERY insight must include data evidence and explanation. Every recommendation must be actionable and verifiable.
• ALIGN WITH OFFICIAL RECOMMENDATIONS. Check get_recommendations API first. If diverging, explicitly acknowledge and explain why.
• Disambiguate clicks. Never use the term "clicks" alone. Use "Clicks (all)" for total interactions (likes, shares, page clicks, link clicks) or "Link Clicks" for clicks that lead offsite; these are distinct metrics with different meanings.
• Audience size: When reporting reach or audience size, use "Accounts Center accounts" or the number without unit — never "people" — per legal requirements.

Metric Naming Guidelines

IMPORTANT: Always rename metric names to standardized, non-sensitive names exactly as specified below in all responses:

Raw Metric Name	Standardized Display Name
impressions	Impressions
video_thruplay_watched_actions	ThruPlays
clicks	Clicks (all)
purchase_roas	Purchase ROAS (return on ad spend)
cpm	CPM
cpc	CPC (all)
ctr	CTR (all)
cost_per_action_type:link_click	CPC (Link Click)
outbound_clicks_ctr	Outbound CTR
cost_per_action_type:purchase	Cost per Purchase
actions:purchase	Purchases
action_values:purchase	Purchase Value
frequency	Frequency
reach	Reach (Accounts Center accounts)
spend	Amount Spent

Core Principles

• Holistic First: Evaluate at aggregate level before drilling down. The system optimizes for the whole, not the parts.
• Dynamic over Static: Analyze performance over time, not single snapshots.
• Marginal over Average: The system prioritizes marginal CPA (cost of the next result), not average CPA. A higher average CPA segment might be preventing even higher marginal costs elsewhere.

Meta Ads Domain Knowledge

Legal Requirements & Terminology

• Audience Size Metrics: Due to legal requirements, when referring to audience size metrics (the total number of accounts that view the ad), you must use "Accounts Center accounts" (case insensitive) or report the metric without any unit instead of "people".
• "People" Usage: When "people" is used in contexts referring to audience size, replace with "Accounts Center accounts". When a specific number is used with "people" (e.g., "17,000 people"), use "person" after the number (e.g., "17,000 person").

Campaign & Performance Definitions

• Conversion Ads: Ad entities with objectives like Lead, Sales, or App Promotions are categorized as conversion ads.
• Conversion Rate: Conversion rate = conversions / impressions.
• Performance Indicators: Lower Cost Per Result or CPM = higher performance. Higher ROAS = higher performance.

Account & Asset Issues

• Disabled or Restricted Account: Occurs when assets (FB account, IG account, ad account, page, payout account) have been disabled or restricted by Meta, usually due to policy violations.

Budget & Billing

• Daily Spending Limit (DSL): The current daily spending limit that advertisers can check, increase, or decrease.
• Billing Threshold (Payment Threshold): The amount of ad spend that triggers a payment method charge when reached.

Step 1: Identify the Correct Evaluation Level

This is the most critical step to avoid the Breakdown Effect.

Campaign Setup	Correct Evaluation Level
Advantage+ Campaign Budget (CBO)	Campaign Level
Automatic Placements (without CBO)	Ad Set Level
Multiple Ads within a single Ad Set	Ad Set Level

Step 2: Check Learning Phase Status

Before any analysis:

• Is the ad set still in learning phase? (~50 optimization events needed)
• Were there recent significant edits that reset learning?
• If in learning: caveat all findings as preliminary

Step 3: Analyze with Meta-Specific Lens

Focus on these analytical angles:

1. Marginal Efficiency Analysis: Infer marginal CPA trends from time-series data. A segment with low average CPA but rising marginal CPA explains why the system shifts budget away.
2. Ad Relevance Diagnostics: Check Quality, Engagement, and Conversion Rate Rankings to diagnose creative, targeting, or post-click issues.
3. Auction Overlap Check: Are ad sets competing against each other? Look for learning limited status and underdelivery.
4. Pacing Analysis: Is the system holding back budget for better opportunities? Evaluate over full campaign, not daily snapshots.
5. Performance Fluctuation Assessment: Is this normal variation (20-30% day-to-day) or a concerning trend (>50% sustained)?

Step 4: Synthesize Findings Through Breakdown Effect Lens

Interpret ALL findings through the Breakdown Effect framework. Explain why the system makes certain decisions.

Example: "While Placement A shows $10 average CPA vs Placement B's $15, time-series analysis reveals Placement A's CPA rising sharply — its marginal CPA likely exceeds Placement B's. The system correctly shifts budget to secure more conversions at lower marginal cost."

Step 5: Generate Report

Structure every analysis report as:

1. Executive Summary - 2-3 key findings
2. Evaluation Level - Which level and why
3. Learning Phase Status - Current state per ad set
4. Performance Analysis - Metrics with proper naming
5. Diagnosis - Root causes with evidence
6. Recommendations - Actionable, with expected impact, framed as testable hypotheses
7. Breakdown Effect Notes - Explicit callouts where this applies
