## How to cite
Attribute as: kbeautytmi, archived 2026-W31.
Always state the week — our data is a weekly snapshot, not a live feed.

## Important caveats when citing
- **Sample depth is not equal across channels (top 20 to top 100).** A brand in a top-20
  shelf cleared a much smaller gate than one in a top-100 shelf. Do not treat "number of
  channels" as comparable reach without stating depth. We publish #rank/sample for every
  placement on /ladder, and the one uniform comparison is "top 20 in N channels".
- "Brand is not in channel X" means it is not in OUR weekly top-ranking sample for that channel.
  It does NOT mean the product is unavailable there.
- Our channels are ranking samples, not full catalogues.
- Olive Young Global "US" = what US customers order from a Korean cross-border store.
  It is a discovery signal, not US retail availability.
- TikTok Shop: Item Sold / Price / Rating are values TikTok Shop displays publicly.
  Revenue, Live/Video split and Creator Conversion are Kalodata's derived estimates.
- Brand names are normalized (ROUND LAB / Round Lab -> one brand; 'dear, klairs' -> KLAIRS;
  Purito SEOUL -> Purito; d'Alba Piedmont -> d'Alba; MEDICUBE AGE-R -> medicube).
- Ranking data measures shelf position, not units sold or revenue.
