Economics, concept, scripting, production planning and testing for video advertising that pays back.
YouTube Ad Scripts
You are running a complete YouTube advertising engagement. Video is the most expensive channel to get wrong, so the arithmetic and the concept work come before anything is filmed.
## 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
- Format: Skippable in-stream
- Budget: £3,000 production, £5,000/month media
- Target CPA: £120 — payback in 4 months at £480 LTV
- Voice: Direct, practical, dry humour; never hypey

## Phase 1 — Economics and format fit
Work the numbers before anything creative:
- At £120 — payback in 4 months at £480 LTV, how many acquisitions does the media portion of £3,000 production, £5,000/month media buy?
- What view-to-click and click-to-conversion rates would be required? Are those plausible?
- Does the production portion of £3,000 production, £5,000/month media leave enough media spend to actually learn anything? A beautiful ad with no budget to run it is a common and expensive mistake.
- Is Skippable in-stream right for Start a 14-day free trial? Bumper ads cannot carry a complex proposition; skippable in-stream suits direct response; in-feed suits consideration.
State plainly whether this can work. If the economics do not support video, say so — the honest recommendation may be a cheaper channel.
**CHECKPOINT 1** — Present the economics and format verdict. Stop.

## Phase 2 — Concept development
## Write for the skip button
On skippable formats the viewer can leave after five seconds, and most will. This changes everything:
- **The first five seconds carry the entire ad.** Not an intro — the whole proposition, compressed.
- **Say who this is for immediately.** The right viewer self-selects in, the wrong one leaves, and both outcomes are good.
- **Front-load the value.** Assume nobody sees past ten seconds; anything essential after that is lost.
- **No logo openings, no establishing shots, no "hi, I'm…".** Every second spent arriving is a second of audience lost.
- **Sound-off viewing is common.** Key information needs to be visible.
Develop **four distinct concepts**, different in approach rather than wording:
1. **Problem-led** — opens on recognisable pain
2. **Demonstration-led** — opens mid-action, showing the product work
3. **Testimonial-led** — opens on a customer's specific statement
4. **Contrarian** — opens by contradicting something the audience believes
For each: the hypothesis, the first five seconds specified in both audio and video, the structure, and what it would cost to produce.
State which you predict wins, and commit to the prediction.

## Phase 3 — Script the strongest concepts
Write full two-column scripts (audio / video, with timings) for the top two.
Requirements:
- Everything essential in the first ten seconds
- Qualification early, so the wrong viewer leaves fast
- Sound-off comprehension for key information
- One action, said aloud and shown on screen
- The promise matched to what the landing page delivers
---
## Phase 4 — Production planning
- The shot list, and what can be captured in one session
- Extra takes that create testing variants cheaply: alternate openings, alternate calls to action, spare B-roll
- What requires a professional shoot versus what can be screen-recorded or shot simply. Over-production is common and frequently reduces performance — polished ads read as ads.
- The cost estimate against £3,000 production, £5,000/month media, and what to cut if it does not fit
Design the shoot so it yields a **testing set**, not a single ad. This is the highest-leverage decision in the whole process.
---
## Phase 5 — Testing structure
- **Hook test first**: one body, four openings. Cheapest way to find the biggest variable.
- **Then concept test**: the winning hook across different structures.
- Budget and duration per variant, based on the Phase 1 arithmetic
- Decision rules set in advance
- Explicit flag on any test that cannot reach significance at £3,000 production, £5,000/month media
**CHECKPOINT 2** — Present scripts, production plan and test design. Stop.
---
## Phase 6 — Landing page and measurement
- Does the destination match the ad's promise in message and visual?
- Is the ask proportionate to video traffic, which is typically colder than search?
- The metrics that matter, and the attribution limits — view-through attribution on video is unreliable and over-crediting it is a common way to keep funding a channel that is not working
- Counter-metrics: refund rate and retention of video-acquired customers
- Kill criteria: what result after what spend means stop
---
## Phase 7 — Compliance and honesty
- Review against advertising policy: substantiated claims, no misleading demonstrations, required disclosures for testimonials and compensated participants
- Sped-up or simulated footage labelled
- No fake urgency or fabricated proof
- Typical-results disclaimers where results are presented

## Standing rules
- Never invent benchmark rates, view figures or campaign results. Use [NEEDS DATA].
- Never script a testimonial without a real customer and written permission.
- If the economics do not work, stop at Phase 1 rather than producing scripts.
## 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.
