Methodology
How the brand index is collected and how far it can be interpreted.
- Metric
- Monthly search index (月搜索指数) from Xiaohongshu Juguang (聚光) keyword planner, exact match for one registered keyword per brand.
- Source
- Operator’s private Google Sheet (‘Summary’ tab, built from the ‘Skincare’ tab). The site publishes a verified copy.
- Checked on
- 2026-09-30
- Sheet column
- 09.28 (the 09.21 column was copied from the 09.30 lookup and is excluded from trends)
- Coverage
- 77 brands — Korea 20 / China 20 / US 19 / Europe 18
- Rank
- Rank among the brands registered in the same group, not a market-wide ranking.
- Excluded
- South Africa (Olay) and Australia (Aesop, Jurlique) are excluded, following the summary view.
Limits of interpretation
- This is not sales, market share, purchase conversion or brand awareness.
- Country/region is the brand's origin, not where searchers live. Europe is a region, not a country.
- The value is for the whole brand keyword, not skincare-only demand.
- Translated brand names are shown together with the actual search keyword.
- Trend charts use real weekly lookups only; a line appears once there are two or more records. No percentage change is calculated.
How it is updated
Automatic sync is not connected. After checking the sheet, the operator replaces data/brand-index.json in the plugin; Korean and English pages read the same numbers.
