Frequently Asked Questions
How long should Instagram Reel captions be?
Keep Reel captions concise but impactful - 50-150 characters is ideal. Start with a strong hook, then add context and CTA. The video is the star, caption supports it.
What makes a Reel go viral?
Viral Reels combine trending audio, strong hooks in the first 3 seconds, high watch time (keep viewers till the end), saves, shares, and comments. Quality video editing is crucial.
Should I use hashtags in Reels?
Yes! Use 3-5 relevant hashtags. Mix broad hashtags (#reels) with niche-specific ones (#workoutreels). The algorithm primarily uses content understanding, but hashtags still help.
What's better: trending audio or original?
Trending audio typically gets more reach initially. But original audio can go viral and lets you be findable when others use your sound. Test both strategies.
