“Marketing copy you write about yourself is optimised for conversion… Voice of customer material, by contrast, is raw and specific. When a client says ‘I didn’t know how to rebuild trust after the reorg and I was terrified I’d lose half my team,’ that’s not a marketing sentence — but it’s a highly citable sentence.” — Lou, 2026-01-22
Session context: 2026-01-22_Mastermind — Lou’s GEARS Alpha session established that citability is won at the felt-experience layer, not the professional-topic layer. This sub-insight owns the schema and GEO facet of the original VOC principle.

Core Idea
There is a structural mismatch between the language coaches use to describe their work and the language their clients use to find them. Marketing copy is optimised for conversion: polished, professional, inside-out, structured around the practitioner’s framework and vocabulary. It also sounds nothing like what a client in distress would type into an AI engine.
Voice of customer (VOC) material — testimonials, call transcript excerpts, discovery call notes, intake form responses — captures the opposite: raw, specific, emotionally resonant language that maps exactly to how a client in a particular situation would describe their experience.
Why this matters for AI citability specifically:
When AI engines interpret queries, they attempt to infer the psychological state, situational context, and causal chain behind the words. Schema built from marketing copy maps to professional topic categories. Schema built from VOC material maps to the felt-experience layer — the beneath-the-keyword layer where citability is actually won.
The closer your schema language is to how a client in distress would phrase their situation, the more likely an AI engine is to retrieve your content as the answer. A sentence like “I didn’t know how to rebuild trust after the reorg” is not a marketing sentence. But it is precisely how someone with that problem would phrase a query — which is why it is more valuable as schema input than anything you wrote about yourself.
This principle underlies why Insight - The Psycho-Causal Graph — Mapping Buyer Psychology Into Your Schema works: the psycho-causal graph is only as accurate as the language it is built from. VOC material is the raw input that populates it with citable, retrievable content.
Practical Application
The Schema Input Audit
Review what you have submitted (or plan to submit) as AI schema or grounding material. Ask:
- How much of it is self-authored professional copy?
- How much is verbatim client language — testimonials, transcript excerpts, intake form phrases?
If the ratio is 80/20 in favour of your own writing, flip it. VOC material carries more citability per sentence than anything you wrote about yourself.
The VOC Collection Sprint
Before your next schema or ontology session, gather:
- 10 verbatim testimonial excerpts — prioritise phrases where clients described how they felt, not just what they got
- 5 transcript excerpts from discovery or coaching calls — specifically moments where the client named their fear, frustration, or confusion
- 3–5 phrases from intake forms that used language surprising to you
Underline every phrase that describes an emotional state, names a specific situational context, or uses vocabulary you didn’t give them. These phrases are your highest-value schema inputs.
