Thumbnail me kya hona chahiye: 5-second test

Thumbnail ko mobile screen par chhota karke dekho — agar 5 second me message samajh nahi aaya to redesign karo. Formula: - Max 3-4 bade words, ek hi idea. - Chehre ka close-up (emotion ke saath) ya ek clear object. - High contrast: dark background par bright text. - Title ko repeat mat karo, thumbnail title ko complete kare. Canva ya Photopea free me kaam kar jate hain. Har 10 video me ek A/B test karo aur dekho kaunsa style zyada CTR deta hai.
