About 개념원리
개념원리 is a Korean math education channel tied to the Gaenyeom Wonri textbook brand. It posts whiteboard lectures and textbook problem walkthroughs, mostly for middle and high school students preparing for school exams and the college entrance test. The channel is low-production and uses a steady format of short problem explanations.
The audience is estimated to be mainly Korean students, though the figures are not confirmed. Median views are about 123 per video against 9,010 subscribers, so reach per upload is limited. No brand work was found in the dossier.
Rates are $150 to $250 per video, the floor for a channel with this median view count. At that rate the effective CPM is well above the $10 to $30 typical of paid ads, so the channel suits education brands with a narrow, study-focused goal rather than broad awareness.
