📈 Telegram kanali Class 12th physics notes analitikasi

Class 12th physics notes (@class_12_physics_notes) Ingliz til segmentidagi kanali faol ishtirokchi. Hozirda hamjamiyat 12 607 obunachidan iborat bo'lib, Taʼlim toifasida 15 857-o'rinni va Hindiston mintaqasida 32 345-o'rinni egallagan.

📊 Auditoriya ko‘rsatkichlari va dinamika

невідомо sanasidan buyon loyiha tez o‘sib, 12 607 obunachiga ega bo‘ldi.

27 Iyul, 2026 dagi oxirgi ma’lumotlarga ko‘ra kanal barqaror faollikka ega. Oxirgi 30 kunda obunachilar soni -410 ga, so‘nggi 24 soatda esa -14 ga o‘zgardi va umumiy qamrov yuqori darajada qolmoqda.

  • Tasdiqlash holati: Tasdiqlanmagan
  • Jalb etish (ER): Auditoriya o‘rtacha 6.00% darajada jalb etiladi. Nashrdan keyingi dastlabki 24 soatda kontent odatda umumiy obunachilar sonining 1.07% ini tashkil etuvchi reaksiyalarni to‘playdi.
  • Post qamrovi: Har bir post o‘rtacha 758 marta ko‘riladi; birinchi sutkada odatda 135 ta ko‘rish yig‘iladi.
  • Reaksiyalar va o‘zaro ta’sir: Auditoriya faol: har bir postga o‘rtacha 0 ta reaksiya keladi.
  • Tematik yo‘nalishlar: Kontent cbse, subject, 12th, pdfs, physics kabi asosiy mavzularga jamlangan.
