In most countries, “where do I get local business data” has one answer and it is Google. Korea is the exception that makes the question interesting, because the platform Koreans use is not the one most tooling targets.
Why this is a real question in Korea
Koreans search on Naver, review on Naver and navigate on Naver. That is not a preference to be argued with; it is the market structure, and it determines which platform accumulated the reviews, the menus and the opening hours.
The practical consequence for a data project: tooling built for Google Places works in Korea and returns a thin version of the country.
Business coverage
Naver carries the long tail — the neighbourhood clinic, the academy, the pharmacy — because those businesses maintain a Naver Place page as a matter of course. Coverage on Google is better in tourist-facing categories in central Seoul and thinner as you move away from both.
Reviews, where the gap is widest
This is the sharpest difference. A Korean business frequently has hundreds of Naver visitor reviews and a handful on Google. For reputation work that is not a gap, it is the difference between having data and not.
Naver also flags is_receipt_verified — reviews it checked against a transaction — which is a stronger quality signal than most review platforms expose at all.
Menus, hours and Naver's own aggregates
- Menus with prices in KRW, as structured items rather than a photo of a menu.
- A ten-band star distribution, not just a mean — why that matters.
- Theme analysis with counts: what visitors mention and how often, computed by Naver.
- Blog review counts, which is a Korea-specific signal with no Google analogue.
Where Naver is worse
Two places, and both are worth knowing before you commit:
Geography. Naver's search pads results with out-of-area businesses and does not mark them. Google Places does not do this. If you use a tool that has not solved it, Naver's coverage advantage is spent on a dataset whose locations are wrong.
Contract. Google Places is a documented API with versioning, quotas and a support path. Naver's public surface has none of that, so a pipeline has to assert on its own field expectations.
How to choose
| If you need | Use |
|---|---|
| Korean review volume | Naver. There is no contest. |
| Menus with prices | Naver. Google does not carry them as structured data. |
| The long tail outside Seoul | Naver. |
| A documented API contract | Google, and accept the coverage. |
| A stable cross-platform identifier | Google's id, joined to Naver on coordinates and name. |
| Both | Naver for content, Google for identity. Join on coordinates. |
Only Naver has been measured by this project, so the Google side of this comparison is about platform properties rather than counted coverage. That is stated in the caveats rather than implied by omission.
