The prompt

Role:
Act as a social media copywriter managing accounts with 500K+ followers.

Context:
Post topic: [POST_TOPIC]. Format: [POST_FORMAT] (photo, carousel, Reel). Audience: [AUDIENCE]. Tone: [TONE]. CTA goal: [CTA_GOAL] (comment, save, share, click link).

Task:
1. Write 3 caption options, each under 150 words.
2. Open each caption with a hook inside the first 125 characters (before the "more" cutoff).
3. Structure: hook, 2-3 short value lines, CTA, then hashtags in a separate block.
4. Provide 2 hashtag sets per caption: a reach set (10-15 mid-size tags) and a niche set (5-8 specific tags).
5. Recommend the best CTA placement for [CTA_GOAL] and one first-comment strategy.

Format:
- Option 1/2/3: caption text, then Reach and Niche hashtag sets
- CTA placement recommendation

Constraints:
- No banned or spammy hashtags (#likeforlike, #follow4follow).
- Max 2 emojis per caption, placed deliberately.
- Every caption must work without the image; no "as pictured" crutches.
- Hashtags must be relevant to [POST_TOPIC]; no generic #instagood filler.

Variables to fill in

Replace each [variable] in the prompt with your own details:

[POST_TOPIC] [POST_FORMAT] [AUDIENCE] [TONE] [CTA_GOAL]

Example input

POST_TOPIC: 5-minute morning skincare routine; POST_FORMAT: Reel; AUDIENCE: women 25-35 into clean beauty; TONE: friendly expert; CTA_GOAL: save

How to use this prompt

Tips for the best results

• Tip: Save-driven captions (tutorials, lists) earn the most algorithmic reach.
• Tip: Rotate hashtag sets monthly — repeated sets get flagged as spammy.
• Tip: Pin a comment with the CTA link or key detail for extra visibility.

Frequently asked questions

How many hashtags should be used?

The prompt generates 10-15 per set. Instagram allows 30, but 10-15 relevant tags outperform 30 generic ones.

Should hashtags go in the caption or comments?

Both work identically for reach. Caption placement is simpler to manage.
