2. Original Content Is King

Recycled videos with watermarks or reposted TikToks are now demoted. Instagram favors Reels created with native camera tools or uploaded with original voiceovers, captions, and music.

Fix: Use Capsai or in-app editing to customize each Reel. Avoid uploading content with visible third-party logos.

3. Engagement Velocity Matters

How quickly a Reel gets likes, comments, saves, and shares in the first hour determines how far it travels.

Fix:
• Encourage interaction early with text overlays like “Comment 🔥 if you relate!”
• Pin your best comment and reply fast to boost activity.

4. Captions Are a New Ranking Factor

Instagram now scans captions for topic relevance and engagement prompts. Reels with useful, keyword-rich captions are more likely to appear on Explore.

Fix: Use Capsai to auto-generate relevant, scroll-stopping text in Hinglish, Hindi, or English.

5. Reel Saves > Reel Likes

Saves and replays are now weighted more heavily than likes. Content that teaches, inspires, or surprises is favored.

Fix: End with a call to action like “Save this for later!” or “Watch twice to catch every tip.”

6. Audio Selection Impacts Reach

Using trending or native audio increases discoverability. But Instagram deprioritizes Reels using copyrighted or reused audio clips from other platforms.

Fix: Use Instagram’s in-app music library or record original audio.

7. Short-Form Watch Time Is Crucial

Your video needs to hold attention until the last second. Completion rate is a key metric now.

Fix:
• Hook viewers in the first 2 seconds
• Use cuts every 2–4 seconds
• Add on-screen text to reinforce key moments

8. Face or Voice Personalization Boosts Reach

Even for faceless creators, adding a human element like voiceover or reaction shots increases algorithmic promotion.

Fix: Use AI voiceovers with Capsai’s tools or reply to comments via voice Reels.

9. Algorithm Favors Consistency

Posting 3–5 Reels per week with consistent themes, visuals, or series formats keeps you in the loop of favorability.

Fix: Plan your Reels in batches using a template - Capsai helps automate captions and hashtags for each clip.

10. Explore Page Is Now Personalized by Watch Behavior

Instagram tailors the Explore page based on what users rewatch, save, or comment on - not just what they follow.

Fix: Focus on content your audience engages with - not just what you want to create. Track insights and optimize accordingly.

Final Tip: Use AI to Stay Ahead

Leverage tools like Capsai to adapt quickly to algorithm changes with real-time analytics, auto-captioning, voiceovers, and keyword optimization - so your Reels always stay discoverable.
