Caption Best Practices

• First sentence = hook (shown in feed preview)
• Main body: 2–4 sentences of context or story
• Hashtag block at end: mix popular (#instagram, #photography) with niche tags
• Emoji sparingly to increase personality
• Call to action (CTA) in last line: "Save this" / "Share with someone who needs this"
