One · The idea

Volume comes from variation, not from more ideas

A monthly creative number is not a list of that many separate ideas. It is a smaller number of base concepts, each built out.

A modest month
180 ads
36 × 5 36 base concepts, 5 assets each
A bigger month
350 ads
50 × 7 50 base concepts, 7 assets each
What you actually invent
36 to 50
ideas, not hundreds

Teams stall because they try to invent the whole number. Thirty six good ideas is a hard month. Three hundred and fifty good ideas is not a month, it is a career. The teams who hit their number are not more inventive than everyone else, they have built a system of variation on top of a normal number of ideas.

The three multipliers

Each one turns one idea into several ads
Multiplier one

Copy and imagery

Hold the format, change the headline promise and the hero image. One layout, five different promises to five different people.

Multiplier two

Three hooks

Change the first ten seconds of a finished video and keep the rest of the cut. One video becomes three ads.

Multiplier three

Format and placement

The same concept as a static, a carousel and a vertical cut. The idea is the same, the container is not.

On the number itself

Not hitting the number in full is fine. The number is a direction, not a test you pass or fail. A month that lands at 120 of a planned 180 has still put 120 new ads into the auction, which is more than enough to learn from. The goal is to get closer each month, and the way you get closer is by building the system once rather than sprinting every month.

Two · Base concepts

One concept, five assets, one layout

Hold the format constant and change the big things: the copywriting headline and the imagery.

Illustrative only. Fernhill is an invented brand created for this page. Nothing here is a real company, a real product or anyone's live creative.
ConvenienceSpeed is the promise, so the image shows the whole ritual happening in one motion.
QualityThe proof is the ingredient list, so the image is the ingredient list.
PriceA price claim needs the product alone and nothing to argue with.
Social proofProof is other people, so other people are the hero.
OutcomeThe promise is a changed afternoon, so the image is the afternoon.

Same layout, same type hierarchy, same wordmark position, same offer lockup, same 4:5 crop. Five different promises to five different people, each paired with imagery that shows that promise. Click any frame to open it larger.

Hold constant
  • Layout and safe areas
  • Type hierarchy and weights
  • Logo or wordmark placement
  • Offer lockup and its position
  • Aspect ratio

These are the parts that cost time and teach you nothing. Lock them once.

Vary
  • The headline promise
  • The hero image
  • The proof element
  • The colour field behind the subject

These are the parts the auction actually reads. Change them properly.

The recipe

Take one layout that has already worked. Write five headlines that each make a different promise to a different person. Pair each headline with imagery that shows that promise rather than decorating it. Ship all five.

A variation is only a variation if the promise changes. Five ways of saying the same sentence is one ad, not five.

Three · The 3 Hooks theory

Change the first ten seconds, keep the rest of the cut

One finished video becomes three ads. Body, proof, offer and call to action all stay exactly where they are.

0:00 0:10 0:30 Hook A Walks toward camera Hook B Product does the thing Hook C Promise burned on screen Shared body, built once Demonstration Proof Offer Call to action This is the expensive part: the shoot, the edit, the grade, the sound, the legal pass. SWAP THE FIRST TEN SECONDS, KEEP ALL OF THIS Ad one Ad two Ad three ONE SHOOT
Hook AHook BHook CShared body

The expensive part of a video is everything after the hook. The shoot, the edit, the grade, the sound and the approvals all live in the body. Once that is paid for, two more ads cost you two more openings. This is the cheapest volume available to any team.

Illustrative only. Fernhill is an invented brand created for this page. Three openings, one body, three ads.
MovementShe starts far and arrives. The frame is still changing at the moment the viewer decides.
Product in motionSomething happens on screen. The powder hits the water and the state of the frame changes.
On-screen promiseThe promise is burned into a moving frame, so it lands with the sound off.

Four rules that make it work

Decide these before the shoot
1

Write the three openings before the shoot

Not after. If the openings are written first, they get shot properly on the day instead of being cut out of leftover coverage.

2

Keep the cut point clean

The body has to start in a place that any of the three openings can hand off to. No dialogue running across the join, no music phrase that only resolves from one opening.

3

Make the three genuinely different

Three approaches, not three phrasings of one line. A walk-in, a product reveal and an on-screen promise are three hooks. Three versions of the same voiceover are one.

4

Test them as three ads

Three separate ads, so each opening gets its own delivery and its own read. Buried inside one ad as three versions, you learn nothing about which opening earned the result.

Four · How to build a hook

Four devices, and what each one looks like on screen

A hook is a mechanical decision, not a flash of inspiration. Pick a device and build it.

1

Movement

Open on motion so the frame changes inside the first second. Walking toward the camera is the reliable version: the subject starts far and arrives, so the frame is still changing at the moment the viewer decides whether to stay.

In practiceSubject enters from depth on a busy street, camera static, she closes half the distance in the first three seconds. Nothing has been said yet and the shot is already moving.
2

Visual hook

Something happens on screen rather than something being described. The product doing the thing beats the product sitting still. A state change, a reveal, a before and after inside two seconds.

In practiceMacro on a glass of clear water, powder falls in and blooms green across the frame. The transformation is the hook and it needs no line of copy to explain it.
3

Copywriting on screen

The promise is burned into the frame during the hook so it reads with the sound off. Most of the feed is muted, so a hook that only works with audio is a hook that works for a minority of impressions.

In practiceSix words, set large in the upper third, held for the full opening. Short enough to read in a glance and placed clear of the platform interface at the top and bottom of the frame.
4

Editing

A visible cut or pattern break inside the first few seconds. The edit itself is the hook: the rhythm change is what tells the viewer something is happening here.

In practiceThree cuts in the first four seconds, each on a different scale, then settle. The opposite failure is the long unbroken establishing shot, which is a beautiful way to be scrolled past.

What usually goes wrong

Easy to spot in a kit review
Starting with the logoThe first second is the most expensive second in the ad and a logo buys nothing with it.
Starting on a static frameIf nothing moves, nothing signals that this is worth a second more attention.
Burying the promisePast five seconds the promise arrives after most of the audience has left.
A hook from a different adIf the opening sets up something the body never delivers, the hold you won is spent on the wrong thing.
Five · October

Putting it together for October's first batch

Six decisions, in order, from the cluster list you already have.

Step one

Start from your cluster list

The clusters are already set. This is not the moment to reopen them.

Step two

Pick the base concept per cluster

One concept per cluster. One is enough, because the concept is about to become five or eight ads.

Step three

Decide the format

Static, carousel or video. Choose the one the concept needs, then lock the layout so it stops being a decision.

Step four

Write the five headline promises

Five promises to five different people. If two of them could swap headlines without anything changing, you have four.

Step five

Book the imagery

One hero image per promise, showing the promise rather than decorating it. Book all five in one session.

Step six

Work back from the kit date

Kits are approved five days before go-live, so the go-live date is what sets the brief date.

The go-live date sets the brief date, not the other way round. Kits are approved five days before they go live, which means a Monday 5 October launch needs the kit signed off on Wednesday 30 September and briefed the week before. Work backwards from the date you want the ads live and the rest of the calendar writes itself.

One cluster, one week, eight ads

Run this for each cluster and the monthly number stops being something you invent and starts being something you schedule.

Who does what

Rosewater plans the batch, writes the briefs, schedules the kits and measures what happens once they are live. Your creative team and your production partners build the ads. This page is the shared language between those two halves, so a brief and a kit mean the same thing on both sides.
