The RMBC method: how Research, Mechanism, Brief and Copy structure a VSL project

The RMBC method is a four-step copywriting process taught by Stefan Georgi: Research the market, find the Mechanism, write a Brief, then write the Copy. The idea behind it is to do the thinking before the writing. Research, the mechanism and a written brief each get their own step, so by the time you write the VSL, every major decision has already been made.

What is the RMBC method, and who created it?

Stefan Georgi is a direct-response copywriter and marketer who created the RMBC Method, which he describes as a systematic approach to writing better sales copy, more consistently, in less time (Stefan Georgi). On his site, RMBC is spelled out as Research, Mechanism, Brief and Copy (The RMBC Method). He teaches it as a paid course, and the newer version, RMBC II, builds much of the process around AI tools and covers assets from VSLs to advertorials, landing pages, upsells and emails (RMBC II).

At a high level, the four steps as he presents them:

What RMBC stands for

The four steps at a high level, as Georgi presents them

1. 1ResearchLearn who the customer is, what problems they face, what they want, and what they like and dislike about the options they've tried.
2. 2MechanismExplain why the prospect's past attempts failed and why this offer works where they didn't.
3. 3BriefOrganize the research and the mechanism into answers you can reuse when you write.
4. 4CopyWrite the sales message from a structured outline, once the earlier steps are done.

Everything below is our own interpretation, with our own templates, written for VSL projects. For the full method, go to the source.

Why separate research and briefing from writing?

Writing a VSL is two jobs: deciding what to say and saying it well. Doing both at once is slow, because every paragraph reopens questions you haven't settled. Who exactly is this for? Why does the problem persist? What proof do we have? Which objection comes first? The draft turns into research written in full sentences.

Separating the jobs fixes three things:

• Reviews get faster. A two-page brief can be approved, challenged or redirected in one meeting. A 3,000-word script is hard to review until it's finished, and by then changes are expensive.
• Rewrites get cheaper. Changing the mechanism in a brief takes an hour. Changing it after the VSL is filmed can mean a re-shoot.
• AI help gets safer. A model given your research and brief can draft variations of leads, transitions and bullets. A model asked to "write a VSL for my product" tends to fill the gaps with invented claims.

The cost math, with invented numbers: say a finished 20-minute VSL takes two days of filming and three days of editing. If a reviewer rejects the mechanism after the edit, you lose a week. If the same objection comes up at the brief stage, you lose an afternoon. Over a year of testing, that difference decides how many ideas you can put in front of traffic.

R: what to research for a VSL

Research has one goal: to understand the viewer's situation better than they could describe it themselves, in their own words. A practical research doc has these sections (our template, not Georgi's):

Two rules make the doc useful. Quote real customers word for word, because those phrases often become your best lines. And keep a source next to every fact, so the copy step never has to guess what's provable. For the awareness row, see the five levels of awareness; for the sophistication row, see market sophistication.

M: finding the mechanism

The mechanism is the explanation that makes the offer believable: why the problem exists or persists (the problem mechanism) and why this solution works where others failed (the solution mechanism). In crowded markets, where every competitor makes the same promise, a credible mechanism is often what earns a skeptical viewer's attention. For how to find and name one, see unique mechanism.

The test of a mechanism has three questions. Is it true? Can you show it? Does it explain the viewer's failed attempts? If any answer is no, keep researching. A mechanism invented to sound scientific is a liability, because it's a claim like any other: the FTC's guidance says advertisers need proof for their claims before the ad runs (FTC Advertising FAQs). This isn't legal advice.

A short fictional example, for SoilCycle, a countertop food-waste appliance:

SoilCycle's mechanism (fictional)

Problem mechanism

Composting in an apartment fails because a closed indoor bin stays too wet and gets too little air, so it smells long before anything breaks down.

Solution mechanism

SoilCycle heats, dries and grinds scraps overnight, so nothing wet is left to smell, and a carbon filter handles the rest.

That last line is where the mechanism step earns its keep. It forces the true claim onto paper before anyone gets creative.

B: writing the VSL brief

The brief is where research and mechanism turn into decisions. It should be short enough to read in ten minutes and specific enough that two different writers would produce recognizably similar VSLs from it. Here's a brief template you can copy (our own):

• One-sentence big idea: the single idea the whole VSL hangs on (see big idea copywriting).
• Viewer and awareness: who's watching, what they already know, what they've tried.
• Traffic and message match: where viewers come from and what the ad promised.
• The promise: what the viewer gets, by when and with what effort, stated in a way you can prove.
• Problem and solution mechanism: one paragraph each, with sources.
• Proof inventory: demonstrations, data, credentials and real testimonials used with permission, each with its source.
• The offer: product, bundles, guarantee, bonuses, and the moment the price appears.
• Objections and answers: the top five, in the viewer's words, each with its answer and where it goes in the script.
• Compliance notes: claims you can make, claims you can't, required disclosures.
• Lead options: two or three different openings to test (see Great Leads).
• Length and runtime: a target length, and the word count it implies at roughly 140 to 160 spoken words a minute.

Get the brief approved before anyone writes a line of script. Disagreements are cheap at this stage and expensive later.

C: writing the VSL from the brief

With a solid brief, the copy step is mostly assembly and craft. Turn the brief into a beat sheet (lead, problem, story, mechanism, proof, offer, guarantee, close), then write each beat for the ear. The VSL script guide covers the beat sheet and runtime math in detail.

Habits that make the copy step go well:

• Write the body first and the lead last. You can only write a lead that lands cleanly once you know exactly what it lands in.
• Pull lines from the research doc. Customer phrases are often the strongest lines in the script.
• Draft fast, then table-read. Read the script aloud to someone who fits the viewer profile, and mark every place they frown, ask a question or drift.
• Check every claim against the brief. If a line makes a claim the brief doesn't support, cut it or go back to research.
• Use AI inside the brief, not instead of it. Ask for ten versions of a transition or five leads built on the brief's mechanism, and never let it add facts. See writing a VSL with AI.

A condensed RMBC run on a fictional VSL

Here's what the four steps look like end to end for SoilCycle.

Research (sample findings, invented for the example): reviewers of indoor compost bins complain about smell and fruit flies; people who quit composting say they gave up in winter or after the first bad smell; apartment renters say they have no outdoor space.

Mechanism: closed indoor bins stay wet and airless, so they smell; heating, drying and grinding overnight leaves nothing wet, and a carbon filter handles odors. Honest limit: the output is dried food waste, not compost.

Brief (excerpt): Big idea: you can keep food scraps out of the trash without living with a smelly bin. Viewer: apartment renters who tried a bin and quit. Promise: no smell on the counter, scraps reduced overnight. Lead options: a problem-solution lead about the bin that made the kitchen smell, and a story lead about a renter whose neighbor complained.

Copy (first lines of the problem-solution lead): "If you've ever kept a compost bin in an apartment, you know the moment it starts to smell. You didn't do it wrong. A closed bin indoors is simply too wet and too airless. Here's what happens when you take the water out of the equation."

Notice what each step contributed. Research supplied the smell and the winter quitters. The mechanism supplied the "why" and the honest limit. The brief locked the promise to what the product does. The copy step only had to make it sound like a person talking.

Common mistakes when using RMBC

Here they are, grouped by the step where each one happens:

Where RMBC goes wrong, step by step

1. 1Research
2. 2Mechanism
3. 3Brief
4. 4Copy

1Research

What happens: Research collects the market's words, problems, failed solutions and objections.

What goes wrong:

• Skipping research because you "know the market". Your memory of the market is a hypothesis. The research doc is evidence.

2Mechanism

What happens: The mechanism explains why past attempts failed and why this offer works.

What goes wrong:

• Inventing a mechanism. A mechanism you can't prove is a claim you can't make.

3Brief

What happens: The brief turns research and mechanism into decisions, so the copy step is execution, not discovery.

What goes wrong:

• Treating the brief as paperwork. A vague brief produces a script that is vague in exactly the same places.
• Writing before the brief is approved. The most expensive feedback is the feedback that arrives after filming.
• Ignoring the traffic. The same product needs a different lead for cold viewers and for retargeted buyers.

4Copy

What happens: With a solid brief, the copy step is mostly assembly and craft.

What goes wrong:

• Dumping research into the script. Research is for deciding. Viewers need the conclusions, not your notes.

How to apply this to your VSL tomorrow

1. Open a blank research doc with the seven sections above and fill in what you already know, marking each item with a source or the word "assumption".
2. Collect 30 real customer phrases about the problem from reviews, forums or support tickets.
3. Write your problem mechanism and solution mechanism in two sentences each, and list the evidence for each.
4. Fill in the brief template, including compliance notes and two lead options.
5. Get the brief approved by whoever signs off on the VSL before anyone writes a line of script.
6. Turn the brief into a beat sheet, write the body first, and write the lead last.
7. After launch, treat the sections where viewers leave as new research for the next brief. In RevvyScales, the second-by-second retention chart marks the pitch, so you can see which beat lost viewers (reading your analytics).
