The VoC research process I run before writing a single word of copy for a health brand. It takes 3 hours and it's worth more than the copy itself.
Every project I take on, landing page, advertorial, presell page, ad scripts, starts with the same process. I don't touch copy until this is done. It takes about 3 hours and it consistently produces better results than any amount of creative brainstorming.
It's called Voice of Customer research. VoC. The process of going through hundreds of customer reviews, forum posts, and social media comments to understand how your buyer actually talks about their problem, what they've tried before, what they're afraid of, and what finally convinced them to buy.
Here's the exact process:
Phase 1: Collect the raw material (45 min)
I gather reviews from 4 sources:
- The brand's own product reviews (5-star, 3-star, and 1-star, each tells a different story)
- Competitor reviews on Amazon (same product category, this is where the richest language lives because Amazon reviewers are incredibly detailed)
- Reddit threads about the problem the product solves (search the relevant subreddit for the condition or pain point)
- Facebook group conversations (search for the product category in relevant health/wellness groups)
I aim for 200-400 data points total. Copy them into a document, one review per line. Don't summarize, keep the exact words. The exact words are the whole point.
Phase 2: Mine for themes (60 min)
I read through every single entry and highlight 5 things:
Pain language, how they describe the problem BEFORE finding a solution. Not the clinical version. The emotional, specific, real version. "I was afraid to pick up my grandkids" hits different than "joint discomfort."
Purchase triggers, what specific incident pushed them to finally buy. After months or years of dealing with the problem, what was the tipping point? Usually it's a specific moment, not a general desire. "My daughter's wedding was 3 months away and I couldn't walk without limping."
Skepticism patterns, what almost stopped them from buying. "I've been burned by supplements before." "I didn't trust the marketing." "The price seemed too high for something that probably won't work." These become objections the copy needs to address.
Outcome moments, not "it works great." The specific, tangible moment they realized it was working. "I woke up and my hands didn't ache for the first time in years." "I made it through a whole yoga class without having to stop." These become the proof elements.
Language patterns, specific phrases that show up repeatedly. If 30 people use the word "exhausted" but zero people use the word "fatigue," the copy should say "exhausted." Your customer's vocabulary is more persuasive than your copywriter's vocabulary.
Phase 3: Build the theme map (45 min)
I organize the highlights into 6-10 distinct themes, ranked by:
- Frequency (how often it appears)
- Emotional intensity (how strongly people feel about it)
- Uniqueness (is this specific to this product category or generic?)
The top 2-3 themes become the foundation for everything, the headline, the opening hook, the mechanism angle, the proof structure, and the CTA.
Phase 4: Match themes to funnel stages (30 min)
- Theme #1 (highest frequency + intensity) → drives the headline and opening of the presell/landing page
- Themes #2-3 → drive the mechanism section and proof stack
- Skepticism patterns → drive the objection handling and guarantee language
- Outcome moments → drive the testimonials and CTA language
The entire piece of copy is built on what the customer already told you they care about. Not what the brand wants to say. Not what the copywriter thinks sounds good. What the customer actually said, in their own words.
Why this works better than brainstorming:
I've done this process on 20+ brands now. The winning headline has come from the VoC data every single time. Not once has the brand founder's preferred angle matched the top VoC theme. Not once.
Founders think about their product the way they built it, ingredients, formulation, quality. Customers think about the product the way they experience it, through the lens of their pain, their fear, their specific Tuesday morning when everything hurt.
The gap between those two perspectives is where great copy lives.
This isn't my proprietary invention or anything, VoC research has been used in direct response copywriting for decades. The great DR writers all did some version of it. I just systematized it for the health and wellness niche because that's where I work.
If you write copy for any health or DTC brand, try this once. Even a shorter version, just go read 100 Amazon reviews for a product in your category and highlight the language that jumps out. You'll find angles you never would have brainstormed.
