About Biyoloji Defteri
Biyoloji Defteri is a Turkish YouTube channel that makes biology lessons for students preparing for the TYT and AYT university entrance exams. The channel posts long lessons on topics such as genetics, enzymes and reproduction, along with short daily question clips and downloadable PDF worksheets. Upload activity has stopped since early 2025, and the most recent lessons were recorded in a plain screen-recorded style.
The audience is likely to be mostly Turkish high school and university-entrance students, with the age and country split estimated from the title and language data rather than measured. Median views are about 84 per video, so reach is small and concentrated.
Brand work is not visible: there are no sponsored videos, no brands detected and no affiliate links in the recent uploads. Estimated rates are $150 to $250 per video. That is well above the $10 CPM typical of paid ads, but the channel is inactive and the audience is small, so it suits education-focused brands willing to test with a single placement.
