Instagram has a built-in tool that transcribes your audio automatically. This is the most efficient way to ensure your keywords are “baked into” the video’s metadata.

  • Record or upload your Reel.
  • Tap the Stickers icon (the smiley face) at the top of the screen.
  • Select the Captions sticker.
  • Once the text appears, tap it to edit any typos. Clear, accurate text helps the algorithm understand your niche.

Beyond the spoken word, adding manual text overlays acts as a “headline” for the search engine.

  • Tap the Aa icon to add manual text.
  • Include broad keywords related to your topic (e.g., “Easy pasta recipe” or “London travel tips”).
  • Keep the text within the “safe zone” (the middle of the screen) so it isn’t covered by the UI elements like the Like button or caption.

This is a hidden gem for searchability. Before you hit share, you can tell Instagram exactly what is in your video.

  • On the final share screen, scroll to the bottom and tap Advanced settings.
  • Scroll down to Write alt text.
  • Describe your video using natural language and key search terms. For example: “A woman showing how to style a trench coat for spring in London.”

The text below your video is just as important as the text on it.

  • Skip the “vibe” captions and be descriptive.
  • Use the first line to state exactly what the Reel is about.
  • Incorporate 3–5 relevant hashtags at the very end to categorise your content.
