How to Use This Skill

When building or reviewing any conversion asset, apply the relevant section below. Score each element, identify the weakest principles, and strengthen them with specific copy/design changes. Every conversion moment should activate at least 3 of the 7 principles.

Landing Page Persuasion Framework

Score each element 1-5 when reviewing or building a landing page.

Above the Fold (first screen, no scroll)

Headline — Must activate a Pain/Desire or Social Proof signal:

• Weak: "The Best Project Management Tool"
• Strong: "The project management tool that 14,000 remote teams switched to when Jira got too complex"
• Score criteria: Specific? Customer-language? Benefit-first? Social proof embedded?

Subheadline — Must handle the #1 objection or elaborate the #1 benefit:

• Weak: "Simple, powerful, beautiful"
• Strong: "Get your team set up in 10 minutes — no training, no migration headache"
• Score criteria: Addresses real fear? Specific? Credible?

CTA (above fold) — Must be low-commitment, specific, and scarcity-aware:

• Weak: "Sign Up"
• Strong: "Start Free — No Credit Card Required"
• Score criteria: Low barrier? Removes fear? Clear next step?

Hero visual — Must show product in use by someone like the prospect:

• Weak: Stock photo of people at a whiteboard
• Strong: Screenshot of actual product with real data visible
• Score criteria: Realistic? Aspirational outcome visible? Customer-type recognizable?

Social Proof Section

Logos: Only recognizable ones. Unrecognizable logos signal low authority.

Testimonials — Score each on 3 dimensions (1-5):

Below 9/15: rewrite or replace.

Numbers: "Used by 12,400 companies" (specific, not round) > "Thousands." Best: "14,000 remote teams have saved an average of 4.2 hours/week" (result embedded).

Objection Handling Section

Every landing page must address top 3 objections before the CTA. Identify them from sales call recordings, support tickets, and exit surveys.

Email Sequence Blueprints

Map each email in a sequence to a specific Cialdini principle.

Welcome Sequence (5 emails over 10 days)

Email 1 — Reciprocity: Deliver value immediately, no ask.

• Subject: "Your [free resource/tool/insight] is ready"
• Body: Pure value — framework, template, or insight usable today
• No CTA other than "reply if you have questions"
• Goal: trigger reciprocity before any sales ask

Email 2 — Authority + Social Proof: Establish credibility.

• Subject: "How [similar company] achieved [specific result]"
• Body: Case study matching the prospect's situation
• Subtle CTA: "Curious if this could work for you?"

Email 3 — Commitment Trigger: Small yes before big yes.

• Subject: "Quick question about your goals"
• Body: Ask them to state their goal. Written commitment to a goal increases purchase likelihood.

Email 4 — Liking: Show the human behind the brand.

• Subject: "The mistake I made that led to [company name]"
• Body: Founder story with genuine vulnerability. Shift from "product" to "person I trust."

Email 5 — Scarcity + CTA: The ask.

• Subject: "Last chance for [offer]" or "Before you miss this"
• Body: Reiterate value, introduce genuine scarcity (trial expiring, cohort closing, price increasing). Hard CTA — clear, specific, one action.

Re-engagement Sequence

Email 1 — Reciprocity: New value, no ask. "We thought you'd find this useful." Email 2 — Social Proof + FOMO: Feature updates + customer results. Email 3 — Personal outreach: Plain text, first name only in subject. "I noticed you haven't started — anything I can help with?" Email 4 — Honest goodbye: "This is my last email for a while." Reverse psychology via consistency — saying goodbye triggers engagement from people who don't want to be written off.

Sales Call Framework (Influence-Mapped)

Opening (0-5 min): Liking + Unity

• Genuine interest: "Before I start, tell me about your situation" — listen for 3+ minutes
• Find genuine connection or similarity
• Mirror their language for how you describe the product later

Discovery (5-20 min): Commitment Trigger via Questions

Ask questions that lead them to articulate their own pain and goals:

• "What's the #1 challenge you're trying to solve right now?"
• "What would ideal look like?"
• "What would achieving that mean for your team?"

When they describe pain in detail, they've committed to having the problem. When they describe the ideal, they've committed to wanting it.

Demo (20-40 min): Authority + Social Proof

• Show features that directly address their stated pain (not a generic tour)
• For each feature: "This is where [similar company] saved 3 hours per week doing X"
• Social proof from customers matching their exact situation
• Authority through specifics: "We ran 200 implementations; here's the pattern we always see"

Handling Objections (40-50 min): Consistency + Reciprocity

1. Validate genuinely (liking and rapport)
2. Reference their earlier commitment: "You mentioned [goal] was critical — how does [objection] weigh against that?"
3. Give information, not pressure
4. If they need to think: "What information would help you make this decision?" — keeps commitment loop

Close (50-60 min): Scarcity + Small Commitment

• Never ask "want to sign up?" — too large
• Ask for next smallest yes: "Would it make sense to do a pilot with your team for 30 days?"
• Name honest scarcity if it exists. If it doesn't, don't invent it.

Pricing Page Psychology

Anchoring

Show highest tier first (or most prominently) to anchor all subsequent prices. Decoy pricing: three tiers where the middle is clearly best value — most buyers choose the middle.

The Goldilocks Effect

Three options → most choose the middle. Structure so middle tier is your preferred sale. Highlight with "Most Popular" or "Best Value" badge. Never name a tier "Basic" — nobody wants to be basic.

Price Presentation

• Annual as monthly equivalent: "$39/month billed annually" > "$468/year"
• Show savings explicitly: "Save $156/year" — loss aversion makes savings feel like avoiding loss
• Per-user pricing: "$8/user/month" feels trivial vs. "$800/month for 100 users"

Risk Reversal

Every pricing page needs:

• Money-back guarantee (remove buyer's remorse risk)
• Free trial (commitment without risk)
• Cancel anytime (no lock-in anxiety)

Prominent guarantees increase conversion more than the refunds they cost.

Objection Handling Through Influence Principles

"It's too expensive."

Principles: Anchoring + Social Proof + Reciprocity

• Anchor upward: "Most companies pay 3x this for a custom solution"
• ROI reframe: "At your volume, this pays for itself in [time period]"
• Social proof: "Companies similar to yours report saving [amount] monthly"
• Give first: "Let me show you the ROI calculator before you decide"

"I need to think about it."

Principles: Commitment + Consistency + Scarcity

• Reference their stated goals: "You mentioned [goal] was critical — what would help you feel confident?"
• Small commitment: "What if we did a 2-week pilot?"
• Honest scarcity: name real deadlines if they exist
• Never: "Take your time" (eliminates urgency entirely)

"We're already using [competitor]."

Principles: Social Proof + Authority + Liking

• Validate current choice (don't criticize competitor — violates liking principle)
• Peer proof: "Many customers switched from [competitor] — here's what drove the change"
• Specificity: concrete functional difference, not generic superiority claims
• Small yes: "Would a 15-minute comparison be worth it?"

"Now isn't the right time."

Principles: Loss Aversion + Commitment + Scarcity

• Cost of inaction: "What does [problem] cost you per month?"
• Reference goals: "How does waiting 6 months affect [goal]?"
• Gentle scarcity if real: "Pricing/capacity changes on [date]"
• Small commitment: "Can we set a check-in for when timing is right?"

The Pre-Purchase Checklist

Run every conversion moment through this before launching:

Reciprocity

• Have we given value before asking for the conversion?
• Is the free offering genuinely valuable?

Scarcity

• Is there a genuine reason to act now?
• Is the scarcity real and communicated honestly?

Authority

• Is credibility established before the CTA?
• Are claims specific (numbers, names, results)?

Social Proof

• Are testimonials from people similar to the prospect?
• Are testimonials specific (results, not just sentiment)?

Commitment

• Is the first ask small and low-risk?
• Have we created prior micro-commitments?

Liking

• Does the copy sound like a human, not a corporation?
• Is there a founder or team story that creates connection?

Unity

• Does the prospect feel part of a community?
• Is there shared identity language?
