Writes paid ad copy across channels using two frameworks baked together:

1. Eugene Schwartz's Awareness Levels (Breakthrough Advertising) - determines what to say based on where the buyer is in their journey
2. Robert Cialdini's 6 Principles of Persuasion (Influence) - determines how to say it to trigger action

The result: every ad set has a distinct angle grounded in buyer psychology, not guesswork.

The two frameworks

Framework 1: Schwartz's 5 Awareness Levels

The biggest mistake in ad copy: writing the same message regardless of where the audience is in their journey. Schwartz's levels fix this.

Level	Who they are	What they believe	What your copy must do
1. Most Unaware	Don't know they have the problem	"Everything is fine"	Tell a story. Don't mention the product. Introduce the problem through emotion or narrative.
2. Problem Aware	Know the pain, don't know solutions exist	"This sucks but that's just how it is"	Name the pain precisely. Agitate it. Show you understand. Introduce the idea that solutions exist.
3. Solution Aware	Know solutions exist, haven't chosen one	"I've been looking into options"	Educate on the category. Show why your approach is right. Don't lead with your brand name yet.
4. Product Aware	Know your product, not convinced yet	"I've heard of them. Not sure if they're right for me"	Features, proof, objection handling. This is where testimonials and case studies earn their place.
5. Most Aware	Ready to buy, need a reason to act now	"I know what I want"	Just the offer. Pricing, urgency, the specific CTA. No education needed.

Rule: Retargeting audiences are typically Level 4-5. Cold audiences are Level 1-3. Never run a Level 5 ad to a cold audience - it will fail.

How to diagnose the level when the user does not know. Ask these three, in order, and stop at the first "no":

1. Has this audience ever visited the site or engaged with the brand? No -> Level 1-3.
2. Do they already use a product in this category (a competitor, a spreadsheet, an internal tool)? No -> Level 1-2. Yes -> Level 3+.
3. Have they hit a pricing, demo or trial page? Yes -> Level 4-5.

If the user cannot answer question 1 from their own analytics or ad platform audience definitions, do not guess the level. Write [NEEDS INPUT: audience source and prior engagement] and produce Level 2-3 copy, which is the only range that is safe when the audience is unknown, because it names a pain without assuming familiarity.

Framework 1b: Schwartz's 5 Stages of Market Sophistication

The second model in Breakthrough Advertising, and the one most ad writers skip. Awareness is about the buyer. Sophistication is about the market: how many claims like yours they have already heard. Two audiences at the same awareness level need different copy if their markets are at different sophistication stages.

Stage	State of the market	What the headline must do	What fails here
1. First	You are the first to make this claim	State the claim plainly. "Get X."	Cleverness. Nobody needs convincing yet.
2. Second	Competitors are making the same claim	Enlarge the claim. Bigger, faster, more specific version.	Repeating the stage-1 claim verbatim.
3. Third	The claim is worn out, nobody believes it	Lead with the mechanism. How it works, not what it does.	Another superlative.
4. Fourth	Competitors are all selling mechanisms	Elaborate the mechanism. Make yours more complete or easier.	A bare mechanism claim.
5. Fifth	The market is exhausted and cynical	Shift to identification: who this is for, what it says about them.	Any product claim at all.

Decision rule: count how many competitors in knowledge/markets/positioning.md make the same headline promise. Zero to one competitor, write stage 1-2 copy. Two to four, go to the mechanism (stage 3). Five or more, or the user says "everyone says that", go to identification (stage 5). If knowledge/markets/positioning.md has no competitor list, ask, and if the user cannot say, default to stage 3 - the mechanism is the safest claim because it is checkable.

Schwartz's own summary of the interaction is worth holding onto: awareness decides what you may say first, sophistication decides how hard you have to work to be believed.

Framework 2: Cialdini's 6 Principles

Each ad variant tests a different persuasion lever. Use all 6 across a campaign, measure which performs for this audience.

Principle	How to apply in ads
1. Social Proof	Numbers, named customers, "X companies use this", peer validation
2. Authority	Awards, publications, expertise, specific credentials
3. Scarcity	Limited spots, pricing ends, cohort-based intake
4. Reciprocity	Free resource, tool, audit, or insight in the ad itself
5. Commitment	Start small ("free trial", "book a 15-min call") before asking for big commitment
6. Liking	Human, relatable, founder voice, shared identity ("built for people like you")

Later editions of Influence add a seventh principle, Unity (shared identity, "one of us"). Treat it as an optional seventh variant, not a replacement for Liking.

Which principle to reach for first, by awareness level:

Awareness level	Try first	Try second	Avoid
1-2 Unaware / Problem Aware	Liking, Reciprocity	Social Proof	Scarcity - there is no desire yet to make scarce
3 Solution Aware	Authority, Reciprocity	Social Proof	Commitment - they have not picked a category winner
4 Product Aware	Social Proof, Authority	Commitment	Reciprocity - a free guide now reads as a stall
5 Most Aware	Scarcity, Commitment	Social Proof	Liking - they do not need warming, they need the offer

Cialdini's own constraint, and it is not optional: every principle only works when the underlying fact is true. Scarcity that is not scarce, social proof that is not proof, and authority that is not earned all convert once and then poison the account. If the fact behind a principle is not in knowledge/services/ or knowledge/company.md, do not use that principle for the variant. Pick a different one.

Channels this skill handles

These are starting defaults recorded at authoring time, not current published specs. Every one of these limits has changed at least once since the platforms launched, several are display-truncation points rather than hard ceilings, and a few differ by placement and by market. Verify in the ad platform's own current documentation before shipping, and where this account's own ad library shows what actually rendered, that wins over the table.

Channel	Format	Key limits (verify before shipping)
LinkedIn Sponsored Content	Single image, carousel, video	150 char intro, 70 char headline
LinkedIn Message Ads	InMail	60 char subject, 500 word body
Google Search	Responsive	15 headlines (30 char each), 4 descriptions (90 char each)
Google Display	Responsive display	5 short headlines, 5 long, 5 descriptions
Meta feed	Image, carousel, video	125 char primary text, 40 char headline
Meta Reels/Stories	Vertical video	15-30 sec script
YouTube pre-roll	Skippable	5-sec hook + 30-sec full script

Inputs needed

• Channel(s)
• Campaign objective: awareness, demand gen, retargeting, conversion
• Audience: persona from knowledge/icp/personas.md + warm/cold/retargeting
• Offer: ebook, demo, trial, webinar, content download
• Landing page URL or topic
• Awareness level of this audience: ask if not clear (cold = Level 1-3, retargeting = Level 4-5)
• Number of variants: default 3 per channel minimum for testing

Process

Step 1: Load context

Read knowledge/brand/voice.md, the relevant persona, knowledge/markets/positioning.md, and the relevant service file.

Step 1b: Triage the brief before writing a single line

Paid media makes bad inputs expensive rather than merely wrong. Run these checks and say what you found. The first three are stop conditions.

Check	Warning sign	Action
Offer matches awareness	Cold audience pointed at a demo booking	Stop. Tell the user the ad will spend for clicks that do not convert, and propose a lower-commitment offer for the cold set.
Landing page matches the ad	The page sells the product, the ad promises a guide	Stop. Message-match failure is the single most common cause of a high CTR with no conversions. Fix the page or change the offer.
Claims are sourced	A number the user cannot point to a source for	Stop. Write [NEEDS INPUT: source for <claim>] and do not write around it.
Audience size	Fewer than a few thousand matched people	Flag it. Below that, four variants will not separate from noise within a normal test window, so cut to two.
Variant count vs budget	More variants than the budget can give meaningful volume	Flag it. Split budget across too many variants and every result stays inconclusive. Recommend cutting to the two strongest hypotheses.
Regulated claim	Health, finance, legal, employment, housing, credit	Flag for legal review before publishing, and check the platform's restricted-category policy, which often bans targeting options as well as wording.

Step 2: Determine awareness level

Ask the user: "Is this audience cold (never heard of you), warm (visited your site, engaged with content), or retargeting (already showed buying intent)?"

Map to Schwartz levels:

• Cold → Levels 1-3 (depending on category awareness)
• Warm → Levels 3-4
• Retargeting → Levels 4-5

Step 3: Build the variant matrix

For each channel, produce variants that cross awareness levels with Cialdini principles:

Awareness Level: [X]
Cialdini Principle: [Y]
Hypothesis: Why this combination should work for this audience

Minimum variant set for a cold LinkedIn campaign targeting Level 2-3:

Variant A: Level 2 (Problem Aware) × Social Proof
Variant B: Level 2 (Problem Aware) × Reciprocity
Variant C: Level 3 (Solution Aware) × Authority
Variant D: Level 3 (Solution Aware) × Liking

Minimum variant set for retargeting (Level 4-5):

Variant A: Level 4 (Product Aware) × Social Proof (testimonial-led)
Variant B: Level 4 (Product Aware) × Scarcity (limited time offer)
Variant C: Level 5 (Most Aware) × Commitment (clear CTA, specific offer)

Step 4: Write per channel

LinkedIn Sponsored Content:

Variant A: [Awareness Level 2 × Social Proof]
  Hypothesis: Cold audience experiencing the problem responds to peer validation
  Intro (≤150 char): <name the pain in their exact words - NO mention of product>
  Headline (≤70 char): <peer proof + outcome>
  Description (≤100 char): <supporting social proof line>
  CTA button: [Learn More | Download | Register]
  Visual brief: <real customer / real result, not product UI>

Variant B: [Awareness Level 2 × Reciprocity]
  Hypothesis: Giving value before asking earns trust at this awareness level
  Intro (≤150 char): <useful insight or stat they can act on immediately>
  Headline (≤70 char): <free resource or guide that solves part of the problem>
  CTA button: [Download | Get free guide]
  Visual brief: <guide cover or data visual>

Variant C: [Awareness Level 3 × Authority]
  Hypothesis: Solution-aware audience needs to be educated on why this approach wins
  Intro (≤150 char): <category framing - "most teams do X. here's why it fails">
  Headline (≤70 char): <our approach + credibility signal>
  CTA button: [See how it works | Watch demo]
  Visual brief: <process diagram or before/after>

Google Search Ads (responsive):

Note: Google Search is typically Level 3-5 (they're searching for a solution)

Headlines (15, each ≤30 char) - mix across principles:
  [Social Proof]: "240+ Teams Use Threadline"
  [Authority]: "[Authority claim from knowledge/services/ - never invented]"
  [Scarcity]: "Free Trial Ends Friday"
  [Commitment]: "Start Free in 5 Minutes"
  [Outcome-led]: "Activate Users in 6 Days"
  [Problem-led]: "Onboarding Killing Trials?"
  ... (fill to 15 mixing approaches)

Descriptions (4, each ≤90 char):
  1. [Social proof + CTA]: "Trusted by [named customers from knowledge/company.md] and [N] teams. Start your free trial today."
  2. [Reciprocity]: "Free onboarding audit included with every trial. See where users drop off in 24 hours."
  3. [Authority + outcome]: "Ship your first onboarding flow in [N] days. [Third-party rating only if it genuinely exists]."
  4. [Scarcity + commitment]: "14-day trial, no card needed. Pricing increases 15-05-2026."

Display path: /<keyword>/<benefit>

Meta feed:

Variant A: [Level 2 × Liking] - relatable human story
  Primary text (≤125 char): <founder/customer voice, problem narrative, first person>
  Headline (≤40 char): <outcome promise>
  Description (≤30 char): <social proof or urgency>
  CTA: [Learn More]
  Visual brief: <authentic human image - real person, not stock>

Variant B: [Level 4 × Scarcity] - retargeting
  Primary text (≤125 char): <they've seen you before - cut to the offer>
  Headline (≤40 char): <specific offer + deadline>
  CTA: [Sign Up | Get Started]
  Visual brief: <product result / dashboard>

Step 5: Voice checks

• Match knowledge/brand/voice.md
• Specific numbers ("47% faster", "6 days", "240 customers")
• Active voice, present tense
• No: "revolutionary", "best-in-class", "synergy", "leverage"
• No claims not documented in knowledge/services/

Step 6: Self-check

Each item is checkable by reading the output file. If you cannot point at the line that satisfies it, it fails.

• Every variant block carries an explicit Awareness Level: N and Cialdini Principle: <name> line
• The variant matrix table has no duplicated (level, principle) pair
• Every variant names a market sophistication stage, and the stage matches the competitor count used to pick it
• In every Level 1-3 variant, the brand and product name do not appear in the first line of copy. Search the file for the brand name and check each hit's position
• Every Level 5 variant contains a specific offer term (price, deadline, trial length, or a named CTA destination)
• Every character-limited field carries its own measured count in the output, written as (N chars), and every one was checked against the platform's current published spec today, not against the table in this skill. Several of these limits are display-truncation points rather than hard ceilings, so never amputate correct copy to hit a number you did not verify
• Every variant has a Hypothesis: line stating what a win would prove, not just what the ad says
• Every variant has a Visual brief: line naming a concrete subject, not an adjective
• Every proper noun, number, rating and customer name in the file traces to a line in knowledge/ or to something the user supplied in this session. List the sources in the README
• The README kill and scale thresholds are numbers from this account's history, or are marked [NEEDS INPUT]. No benchmark from memory

**Awareness level targeted**: [1-5]
**Offer**: <offer>

## Variant matrix
| Variant | Channel | Awareness Level | Cialdini Principle | Hypothesis |
|---|---|---|---|---|

## Test plan
- Run all variants: [X days]
- Kill threshold: <[CTR below Y]>
- Scale threshold: <[CTR above Z, CPL below $X]>

## Benchmarks
- LinkedIn: [UNVERIFIED - replace with this account's own historical CTR]
- Google search: [UNVERIFIED - replace with this account's own historical CTR]
- Meta: [UNVERIFIED - replace with this account's own historical CTR]

Any industry benchmark carried into this section without a named, dated source is a
fabricated number. This account's own last-90-days performance is the only comparison
that is valid for setting a kill threshold.

Step 8: Set the kill and scale thresholds

A variant set without stopping rules runs until someone remembers to look at it. Derive both numbers from this account's own history in knowledge/kpis.md or the ad platform:

1. Kill threshold: the variant's CTR falls below the account's trailing median for that channel, after it has served enough impressions to be readable. If the account has no history, do not invent a number - state the rule as "kill the bottom variant once the top variant has twice its click volume" which needs no benchmark.
2. Scale threshold: cost per qualified lead is below the account's blended target from knowledge/kpis.md. CTR alone is never a scale signal, because the cheapest clicks are usually the least qualified.
3. Minimum run: never judge before the platform's own learning period has completed, and never on a weekend-only or holiday window.
4. Priority when results conflict: conversion rate beats cost per lead, cost per lead beats CTR, CTR beats impressions. A variant that wins on CTR and loses on conversion is a wrong-audience signal, not a copy win.

Rules

• Always identify the awareness level before writing. Copy direction changes completely between levels.
• Never run Level 5 copy to a cold audience. It assumes familiarity that doesn't exist.
• Always produce minimum 3 variants. One ad is not testable.
• Always write the visual brief. Designers cannot ship without it.
• Never fabricate claims. If a user wants a stat not in knowledge/services/, flag it.
• Regulated industries: include "Confirm with legal before publishing" on any health, finance, or legal claim.

Quick reference: awareness level copy direction

Level	First line of copy must...	Never do at this level
1 - Most Unaware	Tell a relatable story with no product mention	Name the brand or product
2 - Problem Aware	Name their pain precisely, in their words	Lead with a solution
3 - Solution Aware	Frame the category, educate on approach	Assume they know your brand
4 - Product Aware	Address objections, show proof	Educate on why the category matters
5 - Most Aware	Just the offer and the CTA	Explain what the product does

Never invent

• No customer name, third-party rating, award, user count, or performance figure unless it is in knowledge/company.md / knowledge/services/ or supplied by the user. The worked examples in this skill are shape illustrations. Never carry a name or a number out of them.
• Filling 15 headline slots is not a licence to generate 12 more claims. Slots you cannot source read [NEEDS INPUT: <what>].
• Never state a benchmark you did not measure. This account's own history is the only valid comparison.

What this skill cannot know

These are limitations of the skill, not of the campaign. Anything in this list that reaches the output must be labelled [UNVERIFIED] there, not quietly asserted.

• Current platform character limits, ad formats, image and video specs, and policy rules. Every table in this file is a starting default from authoring time. Open the ad platform's current documentation before shipping.
• Whether a claim is permissible under the platform's advertising policy in your market. Restricted categories differ by country, and some restrict targeting options as well as wording. Comparative claims and superlatives are separately regulated in several jurisdictions.
• Current CPC, CPL or CTR for this account, industry or geography. No benchmark is stated here for that reason. Pull the account's own trailing numbers.
• Whether the landing page still says what the ad promises. Message match is checked by opening the page, not by reading the brief.
• Whether a named customer has agreed to appear in paid media. Case-study consent and ad consent are different permissions, and paid placement is often excluded from the original agreement.
