Economics, creative strategy, testing, retargeting and diagnostics for a campaign that has to pay back.
Facebook Ads
You are building a complete paid social campaign. The discipline here is arithmetic first — most paid campaigns fail for reasons that were visible in a spreadsheet before any creative was made.
## Brief
- Product:
- Audience: Heads of marketing at 20–200 person B2B SaaS companies
- Problem solved: Scope creep going unnoticed until the project is unprofitable
- Proof available: 31% reduction in write-offs within two quarters
- Desired action: Start a 14-day free trial
- Budget: £6,000/month
- Target CPA: £120 — payback in 4 months at £480 LTV
- Voice: Direct, practical, dry humour; never hypey

## Phase 1 — The economics, before anything else
Work through the arithmetic:
- At £120 — payback in 4 months at £480 LTV, how many acquisitions does £6,000/month buy per month?
- What conversion rate would be required from click to Start a 14-day free trial to hit that, at plausible costs per click for this audience?
- Is that conversion rate realistic, or does it require a rate nobody achieves?
- What is the payback period, and can the business fund the gap?
Then state plainly whether this campaign can work. If the required performance is outside normal ranges, say so now. This is the single most valuable output of the whole exercise and the one most often skipped.
Also assess: is £6,000/month enough to exit the algorithm's learning phase and to run meaningful tests? Under-budgeted campaigns produce noise, and acting on noise is worse than not advertising.
**CHECKPOINT 1** — Present the economics verdict. Stop.

## Phase 2 — Creative strategy
## What actually determines performance
On modern paid social, targeting is largely automated — the algorithm finds the audience. What you control is **the creative and the offer**, and those account for most of the variance in results.
This means: creative volume and creative diversity beat audience micro-segmentation. Five genuinely different creative concepts outperform one concept with twenty audience variations.
Develop **five genuinely distinct concepts** — different in what they lead with, not in wording:
1. Problem-led
2. Outcome-led
3. Proof-led
4. Contrarian
5. Demonstration
For each: the hypothesis it tests, three hook options, the body copy, the call to action, and specific visual direction.
State which you predict will win and why. Commit to the prediction before running anything.
---
## Phase 3 — Testing structure
Design the sequence:
- **Concept phase** — the five concepts, budget per concept, duration, and the decision rule
- **Variation phase** — hooks and formats within the winning concept
- **Scale phase** — what changes when something works
For each phase state the sample needed for a real signal, given the Phase 1 arithmetic. Flag explicitly any test that cannot reach significance at £6,000/month — and reduce the number of variants rather than pretending.
Define what each test *teaches*, not just which variant wins. Learning transfers; a winning ad does not.

## Phase 4 — Funnel and landing page
- Does the landing page match the ad in message, visual and promise?
- Is the ask proportionate to traffic temperature? Cold traffic to a demo form is the most common cause of good ads with bad results.
- Is there one action, or several competing?
- What is the tracking setup, and what will break under current privacy restrictions?
Be specific about attribution limitations. A meaningful share of conversions will not be attributable, and planning as though they will be produces wrong decisions about what to cut.
---
## Phase 5 — Retargeting
- Segments by intent strength, not just by visit
- The message for each, with copy
- Frequency caps and duration limits
- Exclusions: customers, recent purchasers, opt-outs
State the frequency cap explicitly. Over-retargeting is the most common way paid social damages a brand.
**CHECKPOINT 2** — Present creative, testing and funnel plans. Stop.

## Phase 6 — Measurement and diagnostics
- The metrics that matter and the ones that mislead
- The diagnostic tree: what each failure pattern indicates and what to fix
- The counter-metrics: refund rate, churn of paid-acquired customers, support load. Paid channels frequently acquire worse customers, and CPA alone hides it.
- The kill criteria: what result, after what spend, means stop
---
## Phase 7 — Compliance and honesty
- Review all creative against platform policy: personal attributes, health and financial claims, before-and-after framing, misleading interface elements
- No fake urgency, no fabricated social proof, no engagement bait
- Confirm claims are substantiated, since advertising claims carry legal exposure the organic equivalent does not
Close with: what this campaign will realistically achieve, the most likely cause of failure, and what would make paid social the wrong channel for A project management tool for creative agencies entirely.

## Standing rules
- Never invent benchmark CPMs, CPCs or conversion rates. Give ranges only where you are confident, and mark the rest [NEEDS DATA].
- If the economics do not work, say so and stop rather than producing creative for a campaign that cannot pay back.
## Never fabricate
Do not invent statistics, customer names, quotes, case-study numbers, testimonials, or research findings. If you need a figure you have not been given, write [NEEDS DATA] and say what you need. Realistic-sounding invented numbers are the fastest way to destroy credibility with an informed audience.
## Avoid
- Opening with a definition, a rhetorical question, or "In today's fast-paced world".
- The words "delve", "tapestry", "landscape", "game-changer", "unlock", "elevate", "seamless", "robust", and the construction "it's not just X, it's Y".
- Padding: any sentence that restates the previous one in different words.
- Evenly-weighted sections. Real arguments have a centre of gravity.
- Hedging every claim into meaninglessness. Take a position.
