NEXT ICON: public analytics
for Korean YouTube channels
NEXT ICON helps brands, marketing agencies and creators understand Korean YouTube channels: how large they are, how actively they upload, how well their recent videos perform relative to their size, and whether they have worked with brands. It is operated by Crayon Universe Corp., a Korean creative and marketing company. The service is free.
Korean version: 데이터 안내

YouTube API Services we use
All requests use an API key from a server-side collector that runs once a day at 16:10 Korea time. Only public data is requested. The browser never calls the YouTube API directly.
channels.list
snippet, statistics, contentDetails, topicDetails (and id with forHandle)
Channel name, handle, profile image, description, country, subscriber/view/video counts, uploads playlist ID, topic categories. Refreshed daily for every channel. forHandle resolves @handles mentioned in public video descriptions to discover collaborating channels.
playlistItems.list
contentDetails
IDs of the 10 most recent uploads of a channel. Called only when a channel has uploaded new videos or has not been checked for 7 days.
videos.list
snippet, statistics, contentDetails, paidProductPlacementDetails
Title, publish date, duration, view/like/comment counts and the paid product placement flag of recent videos. Also chart=mostPopular (regionCode=KR) to discover popular Korean channels.
search.list
snippet (type=channel, regionCode=KR)
Discovering Korean channels by keyword, within the daily search limit of the project.

Refresh and retention
- Channel and video data shown on the site is refreshed every day.
- Channels and videos that are not refreshed within 30 days are deleted, together with their titles, names and descriptions.
- Daily statistics are kept only for the period the YouTube API Services Developer Policies allow.
- Channels outside Korea, auto-generated “Topic” channels and channels with fewer than 1,000 subscribers are excluded from collection.
- Creators can ask us to remove their channel at ceo@crayonuniverse.com. After verifying ownership we delete all stored data about the channel within 7 days and exclude it from future collection.
- We never request access to Google or YouTube accounts. Users can review and revoke the access of any connected service at https://myaccount.google.com/connections.
Independently calculated metrics
These values are calculated by NEXT ICON, not provided by YouTube. On every page they carry a “자체 지표” (“independently calculated”) label, while values provided by YouTube carry a “YouTube” label.
View rate
Average views of the 10 most recent videos divided by subscribers. View-rate rankings include only channels with at least 10,000 subscribers.
Subscriber growth
Difference between today's and the previous collected subscriber count.
Brand collaboration
A video with YouTube's paid product placement flag, or with a sponsorship disclosure in its title or description. Contact lines such as "for business inquiries" are excluded.
Shorts estimate
Videos of 3 minutes or less, because the API does not state whether a video is a Short.
Expected view range
The middle 50% (25th–75th percentile) of views of recent videos older than 3 days.
Similar-size comparison
Percentile of a channel's average views, view rate, like rate and comment rate among channels in the same subscriber range (and topic, when there are enough channels).
Upload pattern
Uploads per week, weekdays and time of day (Korea time) of recent videos.
Topic category and channel type
Groupings made by this site from YouTube topic categories and channel names (creator, media, company, public institution). They are not official YouTube categories.
What we do not do
- We do not sell, license or redistribute YouTube API data.
- We do not place ads on or within YouTube content or the YouTube player.
- We do not download or store video files, and we do not change any YouTube content.
- We do not present comparisons between channels as contests or battles.
