free-offer-brief
Purpose
Design free lead magnets and tripwire offers that serve as funnel entry points. The free offer IS the first impression — it must demonstrate the same RMBC quality as paid products. A weak lead magnet trains prospects to ignore you. A strong one builds trust, establishes mechanism credibility, and creates reciprocity that drives paid conversions. This skill outputs a complete brief for each offer type: name, format, hook angle, landing page headline, perceived value framing, production cost estimate, and the email follow-up strategy that converts free leads into buyers.
Inputs
| Input | Required | Description | |-------|----------|-------------| | product_line | Yes | The paid product(s) this free offer will lead into — name, price, core promise | | target_audience | Yes | Who the prospect is — demographics, pain points, desires, awareness level | | offer_type | Yes | One of: guide, checklist, quiz, free_shipping, trial, sample | | budget_constraint | No | Maximum production/fulfillment cost per lead (default: $0 for digital, specify for physical) |
Execution Protocol
Step 1 — Load Framework Context
Read rmbc-context/SKILL.md to load RMBC framework definitions. Free offers apply RMBC in miniature — Research identifies what the audience values enough to trade their email for, Mechanism gives the free offer a unique angle that previews the paid product's approach, Brief structures the offer for maximum perceived value, Copy makes the landing page convert.
Step 2 — Assess Offer Type Fit
Evaluate the chosen offer type against the audience and product line:
| Offer Type | Best For | Perceived Value Driver | Fulfillment Cost | |------------|----------|----------------------|-----------------| | Guide | Info products, services — audience wants education | Depth of insight, specificity | $0 (digital PDF) | | Checklist | Action-oriented audiences — want quick wins | Immediate usability, saves time | $0 (digital) | | Quiz | Broad audiences — curiosity-driven, personalization | Self-knowledge, custom results | $0 (software) | | Free+Shipping | Physical products — supplements, beauty, gadgets | Tangible product in hand | $3-15 COGS + shipping | | Trial | Software, subscriptions — need to experience value | Risk-free experience of the real product | Variable (usage cost) | | Sample | Consumables — supplements, food, skincare | Taste/test before committing to full supply | $2-8 COGS + shipping |
If the chosen type is a poor fit for the product line, flag the mismatch and recommend a better type before proceeding.
Step 3 — Design the Offer
Build the complete offer brief:
Offer Name
- Must be specific and outcome-driven: "The 7-Day Gut Reset Checklist" not "Free Health Guide"
- Include a number, timeframe, or specificity marker
- The name alone should communicate value
Format and Scope
- Define exactly what the prospect receives and in what format
- For digital: page count, sections, bonus elements
- For physical: product specs, quantity, packaging
- Scope rule: solve ONE specific problem completely — never try to cover everything
Hook Angle
- The single most compelling reason to claim this offer NOW
- Must connect to the paid product's mechanism without giving it all away
- The hook should create a curiosity gap that the paid product fills
Landing Page Headline
- 3 headline variations, each using a different RMBC lead pattern:
- Curiosity/mechanism-led
- Outcome/desire-led
- Problem/pain-led
Perceived Value Framing
- What this would cost if sold separately (credible anchor)
- Why it's being offered free (the reason must be believable)
- What makes it genuinely valuable, not just "free content"
Production Cost Estimate
- Itemized: content creation, design, fulfillment, platform/software
- Cost per lead at projected volume (100, 1000, 5000 leads)
- Flag if cost exceeds budget constraint
Step 4 — Map the Email Follow-Up Strategy
The free offer is the beginning, not the end. Define the conversion path:
| Email | Timing | Purpose | Content Direction | |-------|--------|---------|-------------------| | Delivery | Immediate | Deliver the offer + set expectations | Here's your [offer] + what to do first | | Quick Win | Day 1-2 | Help them USE the offer and get a result | One action step from the guide/checklist | | Mechanism Tease | Day 3-4 | Introduce the paid product's mechanism | "The guide covers X, but here's what it can't do alone..." | | Social Proof | Day 5-6 | Show results from paid customers | Testimonial + before/after | | Offer | Day 7 | Present the paid product with a transition incentive | Special pricing for free offer recipients |
Step 5 — Validate the Funnel Bridge
Confirm the free offer creates a logical bridge to the paid product:
- [ ] The free offer solves a real problem (not manufactured)
- [ ] Consuming the free offer naturally reveals the need for the paid product
- [ ] The mechanism preview in the free offer matches the paid product's mechanism
- [ ] The email sequence has a clear, non-pushy path from free to paid
- [ ] The perceived value justifies giving up an email address

### FUNNEL BRIDGE VALIDATION
[Pass/fail on each bridge criterion]
Quality Criteria
- Offer name must be specific and outcome-driven — generic names like "Free Guide" signal low value
- Hook angle must create a curiosity gap that the paid product fills — not give away the whole mechanism
- Landing page headlines must use three distinct RMBC lead patterns — not three variations of the same angle
- Perceived value anchor must be credible — a $5 checklist positioned as "$497 value" destroys trust
- Production cost must be itemized and compared against budget constraint — no surprises
- Email follow-up must bridge to the paid product within 7 days — longer sequences lose momentum
- The free offer must solve a real problem completely enough to build trust, but not so completely that the paid product feels unnecessary
- Specificity gate: Every recommendation must include a number, name, or timeframe — no "high value" or "strong appeal"
- Mechanism quantification: When referencing the mechanism, include at least one specific data point (number, timeframe, study reference)
- Audience journey: The brief must reference where the reader IS (what they've tried, what's failing) — not just who they are demographically
- Proof diversity: Use at least 2 different proof types (testimonial, statistical, authority, case study) — do not rely on a single proof mode
- Objection handling: The brief must address "what's the catch?" and "is this worth my email?" — include at least 2 trust-building elements (social proof, no-spam promise, instant access, preview of value)
