Ad Library Teardown Agent Skill

Ad Library Teardown

Overview

Analyze public ads to understand a competitor's messaging, offers, creative strategy, and testing angles. The output should be a practical teardown marketers can use to write better ads or decide what to test.

When to Use

Use this skill when the user asks to:

• analyze a competitor's active ads
• search Meta/Facebook, Google, or LinkedIn ad libraries
• extract ad hooks, CTAs, claims, offers, and landing page angles
• compare ad messaging across competitors
• summarize video ad transcripts
• generate ad test ideas from competitor ads

Data Sources

| Ad library | Search/list endpoint | Detail endpoint | Transcript endpoint |

|---|---|---|---|

| Meta/Facebook | /v1/facebook/adLibrary/search/ads, /v1/facebook/adLibrary/company/ads, /v1/facebook/adLibrary/search/companies | /v1/facebook/adLibrary/ad | /v1/facebook/adLibrary/ad/transcript |

| Google | /v1/google/adLibrary/advertisers/search, /v1/google/company/ads | /v1/google/ad | n/a |

| LinkedIn | /v1/linkedin/ads/search | /v1/linkedin/ad | n/a |

Workflow

• Find the advertiser
• Use company search endpoints when the user provides only a brand name.
• Use domain/advertiser/page IDs when available.

• Fetch active ads
• Prefer active ads unless the user asks for historical analysis.
• Capture platform, advertiser/page, ad ID, start date, creative type, text, headline, CTA, destination URL, and source URL.

• Fetch details for representative ads
• Enrich the ads with detail endpoints.
• For video Meta ads, fetch transcripts when available.

• Cluster messaging

Group ads by:

• pain point
• persona
• offer
• proof/social proof
• feature/benefit
• objection handled
• comparison/alternative angle
• urgency/discount

• Extract swipeable elements
• hooks
• headlines
• primary text patterns
• CTAs
• claims
• offers
• visual/creative concepts

• Recommend tests

Suggest tests based on repeated patterns and gaps, not random ideas.

Common Pitfalls

• Do not claim an ad is winning just because it is active. Say it is active or repeated; performance is not public unless the endpoint returns it.
• Do not ignore repeated ads. Repetition is often a useful signal.
• Do not invent spend, conversion rate, or targeting unless public data includes it.
• Do not skip video transcripts when the user asks for hooks or messaging from video ads.
