Difficulty: Beginner → Intermediate
Model: GPT-4 / Claude / Gemini
Use Case: Social Media, Short-Form Copy, Platform Optimization

Why This Prompt Exists
Most social media headlines fail because they’re too long for the feed.

You get:

  • 15-word headlines cut off mid-sentence (no click)
  • the same headline on every platform (different behavior ignored)
  • no character count awareness (Twitter vs. Instagram are different games)
  • headlines that work on desktop but not mobile
  • no emoji strategy (too many or none at all)

But social media is not email.

Each platform has different attention patterns.

  • Twitter/X: 70-100 characters max, news-first
  • LinkedIn: professional, benefit-driven, longer acceptable
  • Instagram: visual-first, emojis OK, under 8 words ideal
  • Facebook: conversational, question-heavy
  • Threads/Bluesky: platform-native, casual

Without platform optimization, your headlines get cut off or ignored.

This framework forces AI to write headlines that fit.

The Prompt
Assume the role of a social media copywriter who knows that long headlines don't get read.

Your task is to generate platform-optimized headline variants.

Generate 2 headline versions for EACH platform (10 total), each under 10 words:

1. TWITTER/X
   - News-first, under 70 characters
   - No wasted words

2. LINKEDIN
   - Professional but punchy
   - Benefit-driven

3. INSTAGRAM
   - Emojis allowed
   - Under 8 words ideal

4. FACEBOOK
   - Conversational
   - Question or command format

5. THREADS / BLUESKY
   - Platform-native tone
   - Casual, in-the-know

PLUS:
- Character count for each headline

INPUTS:

Longer Headline or Key Message:
[WHAT DO YOU NEED TO SHORTEN?]

Platform Mix:
[WHICH PLATFORMS ARE YOU POSTING ON?]

Target Audience:
[WHO ARE YOU TALKING TO?]

Brand Voice:
[PROFESSIONAL / CASUAL / EDGY / WARM]

Emoji Policy:
[NO EMOJIS / OK SPARINGLY / ENCOURAGED]

RULES:
- Each headline must be under 10 words
- Include character count for every headline
- Twitter/X headlines must be under 70 characters
- Platform-native tone: casual for Threads, professional for LinkedIn
- If the original headline is over 15 words, warn that it needs rethinking
How To Use It
  • Never post the same headline on every platform — they’re different games.
  • Twitter/X: front-load the value (first 35 characters are most visible).
  • LinkedIn: benefit-driven headlines outperform clever ones.
  • Instagram: the headline is secondary to the visual — keep it short.
  • Facebook: questions drive comments, which drive reach.
Example Input

Longer Headline or Key Message: “How to double your email open rates using these 5 subject line templates that actually work”

Platform Mix: Twitter, LinkedIn, Instagram, Facebook

Target Audience: Solopreneurs and small business owners

Brand Voice: Helpful and direct

Emoji Policy: OK sparingly

Why It Works
Most social headlines fail because they’re one-size-fits-all.

This framework improves outcomes by forcing:

  • platform-specific optimization (different behaviors)
  • character count awareness (display limits)
  • under-10-word discipline (scannability)
  • platform-native tone (fit the culture)
  • emoji strategy (enhance, don’t distract)

Great social headlines don’t work everywhere — they work where they’re posted.
