Instagram algorithm captions

Write captions to get attention and interaction — practical steps:

  • Hook in the first 2–3 words (benefit, surprise, or emoji) so it shows in-feed.
  • Lead with 1–2 keywords related to your niche for discovery.
  • Use a single, specific CTA (save this, tag a friend, answer X) — ask one clear question to prompt comments.
  • Make it scannable: short opening line, line breaks, 2–3 emojis, then 1–3 short paragraphs for longer stories.
  • Add alt text to every post and tag relevant accounts/locations.
  • Use 3–10 targeted hashtags (keep extras in the first comment) and 1-2 niche keywords in the caption.
  • Post when your audience is active and reply to comments within the first hour to boost reach.
  • Prefer carousels/Reels to increase time-on-post. A/B test hook, length and CTA; save 3 caption templates that perform and rotate them.

Which post format do you want caption examples for — Reels, carousel, or single-photo posts?
