Carousels and Polls: Format Recipes for 2–3x Reach

Why these formats win

• Carousels/documents: ~1.5x reach multiplier with the best dwell time. Sweet spot: 8–10 slides, 25–50 words each, vertical 1080×1350.
• Polls: ~1.6x reach multiplier and the fastest engagement. Best with 3 options and 7-day duration.

Carousel recipe (copy/paste)

• Slide 1 (hook): Bold promise or contrarian claim. Example: “Stop posting daily. Do this instead.”
• Slides 2–7 (value): Checklist, framework steps, or mini-case studies. Keep 1 idea per slide.
• Slide 8–10 (action): Summary + CTA for comments (“Which step will you try first? 15+ words.”) and saves (“Save this for your next retro”).
• Formatting:
  • 1080×1350 (4:5), vertical only.
  • 25–50 words per slide. Avoid dense paragraphs.
  • Minimal hashtags (≤3) and <5 tags.

Poll recipe (3-option, 7-day)

• Question: 140 characters or less. Specific and identity-based. Example: “Where does your LinkedIn pipeline stall most often?”
• Options: 3 choices, <30 characters each. Example: “No comments,” “Weak hook,” “Posting cadence.”
• Context: Add 1–3 bullet points above the poll explaining why you’re asking.
• CTA: “Vote, then explain your choice in 15+ words so we can compare.”

When to use each

• Carousels: Teaching frameworks, step-by-step guides, resource roundups, mini case studies, swipe files.
• Polls: Market sensing, pre-launch validation, reframing debates, sparking comment threads.

Common mistakes (and fixes)

• Too many slides: >12 drops completion. Trim to 8–10.
• Square layout: Costs 20–35% reach. Go vertical.
• No comment prompt: Poll votes without comments leave reach on the table. Add a 15+ word question.
• Posting twice a day: Triggers cadence penalties. Keep ≥24 hours between publishes.

Ready-to-use prompts

• Carousel: “7 mistakes that quietly kill your LinkedIn reach (and what to do instead).”
• Carousel: “Swipe file: 5 hooks that drive 50+ comments. Save for later.”
• Poll: “Which format gets you the most saves? Carousels, polls, or images? Tell us why.”
• Poll: “If you had to drop one lever for 30 days, which would it be? Hooks, CTAs, or timing?”

Lean into formats the algorithm already favors, and design every slide or option to invite conversation, beyond clicks.
