Best practices

  • Keep feed images under 8 MB; SocialRobot scales toward 1440px.
  • Use 1080×1920 for Stories.
  • Carousels support 2–20 items.

Common mistakes

  • Oversized PNGs that fail the 8 MB cap.
  • Single-image “carousels” under the 2-item minimum.
  • Video longer than five minutes.
