How do you measure "share of voice" in AI answers?

We run a fixed set of 30 category buy-intent prompts through ChatGPT and Gemini every week and log each brand mention and citation against the specific prompt, engine and week on a dashboard we built. Share of voice is one brand's mentions as a percentage of all brand mentions across that set. The number in this case study is the 2026-W36 snapshot.

Why would a B2B dental-materials distributor care about AI answers?

Because buyers increasingly ask an assistant "where do I buy reputable dental materials" before they open Google, and act on the names that come back. If no assistant names you at that step, you're out of consideration before the buyer reaches your site — and it never shows in web analytics, because the visit never happens.

Is this the same as SEO ranking?

No. This measures presence and share inside AI-generated answers, not blue-link position in search results. The two can move independently, so we report the AI-answer number on its own and don't fold search-ranking figures into it.

Was Oroca named with consent, and does this include sales figures?

Oroca is named with client approval. The dashboard measures presence in AI answers only — we don't attribute revenue or orders to it, and a past measurement for one brand isn't a promise of the same result for another.

CASE · AI VISIBILITY · SHARE OF VOICE

From invisible in AI answers
to 41.2% share of voice.

Oroca distributes dental materials to clinics and labs across Ho Chi Minh City and Hanoi. Its buyers increasingly ask an AI assistant for a supplier before they open Google — and at first, the assistants never named Oroca. Today Oroca holds 41.2% share of voice in its category's AI answers: the outright #1, about three times the nearest rival, and more mentions than the next three competitors combined.

01 · The context

Buyers ask an AI before they ask Google.

Oroca supplies B2B dental materials to clinics and labs in Ho Chi Minh City and Hanoi. More and more of its buyers open an AI assistant first — "where do I buy reputable dental materials in Vietnam?", "authorized distributor in Hanoi" — and act on the names that come back.

If an assistant doesn't mention you at that moment, you're out of consideration before the buyer ever reaches your site. That's a visibility problem that never shows up in web analytics, because the buyer never arrives to be counted.

02 · Before

Not in the answer at all.

Before this work, Oroca did not appear in AI answers for its category. Ask an assistant for a reputable dental-materials supplier in Vietnam and it named competitors — not Oroca. Share of voice was effectively zero.

There was also no way to see it. Nobody was measuring which brands the assistants named, so the gap was invisible as well as unaddressed.

03 · What we did

Build the measurement, then move the number.

Two things had to exist before anything could improve: a way to measure presence in AI answers, and structured signals clear enough for the assistants to resolve who Oroca is, where it operates, and what it sells.

Built a 30-prompt set of real B2B dental buy-intent queries for the Vietnam market and ran it on a weekly schedule across ChatGPT and Gemini.
Built a dashboard that tracks share of voice plus mention and citation rate for every prompt, engine and week — our own measurement tool, not a re-skinned third-party report.
Strengthened entity signals on oroca.vn — Organization and LocalBusiness markup — so AI systems resolve the right identity and the right locations (Ho Chi Minh City and Hanoi).
Structured product pages so specific items are quotable — Product schema (brand, SKU, price, in-stock availability) plus breadcrumbs and clear descriptions, giving assistants the exact details they cite.

04 · How we measured

Every mention tied to a prompt, an engine and a week.

Each week the same 30 category prompts run through ChatGPT and Gemini, and every brand mention and citation is logged against the exact prompt, engine and week on the dashboard. Share of voice is Oroca's mentions as a percentage of all brand mentions across that set.

The figures below are the 2026-W36 snapshot. Because the set runs on a schedule rather than once, this is a verifiable trend line the client can click into — not a single screenshot.

05 · The result

#1 share of voice — more than the next three rivals combined.

In the 2026-W36 snapshot Oroca holds 41.2% share of voice — 42 of the category's brand mentions — the outright #1. That is about three times the nearest rival (Dentaluck, 13.7%) and more mentions than the next three competitors combined (42 versus 39). The remaining five competitors share the other 58.8%.

Across the 30-prompt set Oroca's AI mention rate is 70% — 19 cited and 23 mentioned — and it holds on both engines: ChatGPT 76.7%, Gemini 63.3%.
