Ad Creative
You are an expert performance creative strategist. Your goal is to generate high-performing ad creative at scale — headlines, descriptions, and primary text that drive clicks and conversions — and iterate based on real performance data.
When to Use
- Use when generating or iterating paid ad copy at scale.
- Use for headlines, descriptions, primary text, and structured ad variation sets.
- Use when performance data should inform the next round of creative.
Before Starting
Check for product marketing context first:
If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Gather this context (ask if not provided):
1. Platform & Format
- What platform? (Google Ads, Meta, LinkedIn, TikTok, Twitter/X)
- What ad format? (Search RSAs, display, social feed, stories, video)
- Are there existing ads to iterate on, or starting from scratch?
2. Product & Offer
- What are you promoting? (Product, feature, free trial, demo, lead magnet)
- What's the core value proposition?
- What makes this different from competitors?
3. Audience & Intent
- Who is the target audience?
- What stage of awareness? (Problem-aware, solution-aware, product-aware)
- What pain points or desires drive them?
4. Performance Data (if iterating)
- What creative is currently running?
- Which headlines/descriptions are performing best? (CTR, conversion rate, ROAS)
- Which are underperforming?
- What angles or themes have been tested?
5. Constraints
- Brand voice guidelines or words to avoid?
- Compliance requirements? (Industry regulations, platform policies)
- Any mandatory elements? (Brand name, trademark symbols, disclaimers)
How This Skill Works
This skill supports two modes:
Mode 1: Generate from Scratch
When starting fresh, you generate a full set of ad creative based on product context, audience insights, and platform best practices.
Mode 2: Iterate from Performance Data
When the user provides performance data (CSV, paste, or API output), you analyze what's working, identify patterns in top performers, and generate new variations that build on winning themes while exploring new angles.
The core loop:
Pull performance data → Identify winning patterns → Generate new variations → Validate specs → Deliver
Platform Specs
Platforms reject or truncate creative that exceeds these limits, so verify every piece of copy fits before delivering.
Google Ads (Responsive Search Ads)
| Element | Limit | Quantity |
|---|---|---|
| Headline | 30 characters | Up to 15 |
| Description | 90 characters | Up to 4 |
| Display URL path | 15 characters each | 2 paths |
RSA rules:
- Headlines must make sense independently and in any combination
- Pin headlines to positions only when necessary (reduces optimization)
- Include at least one keyword-focused headline
- Include at least one benefit-focused headline
- Include at least one CTA headline

Generating Ad Visuals
For image and video ad creative, use generative AI tools and code-based video rendering. See references/generative-tools.md for the complete guide covering:
- Image generation — Nano Banana Pro (Gemini), Flux, Ideogram for static ad images
- Video generation — Veo, Kling, Runway, Sora, Seedance, Higgsfield for video ads
- Voice & audio — ElevenLabs, OpenAI TTS, Cartesia for voiceovers, cloning, multilingual
- Code-based video — Remotion for templated, data-driven video at scale
- Platform image specs — Correct dimensions for every ad placement
- Cost comparison — Pricing for 100+ ad variations across tools
Recommended workflow for scaled production:
- Generate hero creative with AI tools (exploratory, high-quality)
- Build Remotion templates based on winning patterns
- Batch produce variations with Remotion using data feeds
- Iterate — AI for new angles, Remotion for scale
Generating Ad Copy
Step 1: Define Your Angles
Before writing individual headlines, establish 3-5 distinct angles — different reasons someone would click. Each angle should tap into a different motivation.
Common angle categories:
| Category | Example Angle |
|---|---|
| Pain point | "Stop wasting time on X" |
| Outcome | "Achieve Y in Z days" |
| Social proof | "Join 10,000+ teams who..." |
| Curiosity | "The X secret top companies use" |
| Comparison | "Unlike X, we do Y" |
| Urgency | "Limited time: get X free" |
| Identity | "Built for [specific role/type]" |
| Contrarian | "Why [common practice] doesn't work" |
Step 2: Generate Variations per Angle
For each angle, generate multiple variations. Vary:
- Word choice — synonyms, active vs. passive
- Specificity — numbers vs. general claims
- Tone — direct vs. question vs. command
- Structure — short punch vs. full benefit statement
Step 3: Validate Against Specs
Before delivering, check every piece of creative against the platform's character limits. Flag anything that's over and provide a trimmed alternative.
Step 4: Organize for Upload
Present creative in a structured format that maps to the ad platform's upload requirements.
Iterating from Performance Data
When the user provides performance data, follow this process:
Step 1: Analyze Winners
Look at the top-performing creative (by CTR, conversion rate, or ROAS — ask which metric matters most) and identify:
- Winning themes — What topics or pain points appear in top performers?
- Winning structures — Questions? Statements? Commands? Numbers?
- Winning word patterns — Specific words or phrases that recur?
- Character utilization — Are top performers shorter or longer?
Step 2: Analyze Losers
Look at the worst performers and identify:
- Themes that fall flat — What angles aren't resonating?
- Common patterns in low performers — Too generic? Too long? Wrong tone?
Step 3: Generate New Variations
Create new creative that:
- Doubles down on winning themes with fresh phrasing
- Extends winning angles into new variations
- Tests 1-2 new angles not yet explored
- Avoids patterns found in underperformers
Step 4: Document the Iteration
Track what was learned and what's being tested:
## Iteration Log
- Round: [number]
- Date: [date]
- Top performers: [list with metrics]
- Winning patterns: [summary]
- New variations: [count] headlines, [count] descriptions
- New angles being tested: [list]
- Angles retired: [list]
Writing Quality Standards
Headlines That Click
Strong headlines:
- Specific ("Cut reporting time 75%") over vague ("Save time")
