LinkedIn Algorithm 2025: The Complete Content Format Strategy Guide

By the end of this post, you'll know exactly which format to use for every type of content you create—not just what performs best overall, but what performs best for you based on your goals and available time.

What Changed in 2025: The LinkedIn Algorithm Rebalance

LinkedIn's "Brew 360" algorithm update fundamentally changed how content formats perform. Let me show you the data.

Here's what happened to the major formats:

• Carousels: Remained stable with the highest reach multiplier
• Text and Image: Slight reach increase, significant engagement boost
• Video: Went from king to commoner—the biggest casualty of 2025
• Polls: Increased reach but dramatically decreased engagement
• Infographics: Maintained strong performance across all metrics

The biggest lesson here? There's content that works better for reach, and content that works better for engagement. Understanding this distinction is critical for your strategy.

Format #1: Text and Image (The Most Underrated Format)

I consider this the most underrated format—and here's why.

Text and image might seem boring because it's so simple, but it delivers the best bang for your buck.

The Numbers

• 65% of all LinkedIn posts use text and image
• Slight increase in reach (no algorithm penalty)
• Significant engagement rate increase in 2025
• Takes only 5 minutes to create (compare that to 30-60 minutes for carousels)

Best Practices for Text and Image Posts

• Use vertical images: You get more space in the feed—a 32% boost just from taking up more real estate
• Personal photos win: Nobody wants stock images. People want to see you. Use AI to create personal photos if needed
• Try selfie-style content: Authenticity performs
• Build a library: Keep 20-30 professional photos you can rotate through
• Add multiple images when storytelling: Great for personal posts where the image count actually supports the narrative

The Simple Formula

Write your post → Attach an image of yourself → Done.

Your facial expression should match your post's intent. It can be a holiday snapshot or a professional office photo. The versatility is incredible—use it for personal stories, quick tips, opinions, and day-to-day content.

If you don't want to do anything else, just stick with text and image. It's a super solid baseline.

Format #2: Carousels (The Engagement Champion)

Everyone's obsessing over carousels—and for good reason.

Why Carousels Dominate

• Biggest reach multiplier of any format
• Highest engagement rates
• Most shares
• Longest lifespan: Up to 1-2 weeks (compared to 1-5 days for text and image)
• Only 10% of creators have ever posted a carousel (low competition)

What Changed for Carousels in 2025

The ideal length dropped from 12-13 slides to 6-9 slides. Why? Carousel fatigue.

Here's the critical metric: If click-through drops below 35%, you get a visibility penalty.

That means if you have 7-8 slides, you need people clicking through at least 3-4 of them. The way to achieve this? Tell a story that draws people in and makes them want more.

Text-oriented carousels outperform image-oriented carousels because it's easier to tell compelling stories with short text snapshots.

The Perfect Carousel Formula

• 6-9 slides maximum (never upload 20-slide novels)
• Keep captions under 100 characters per slide
• Create a compelling title/hook (just like your post)
• Use simple language for easy consumption
• Include a call-to-action on the final slide (share, follow, comment)
• Add your face/avatar somewhere in the carousel for authority
• Tell a story: Hook → Before → Problem → Solution → How-to → Result → CTA

Previously, carousels were tip-focused ("10 Best Tips" with one slide per tip). These still work, but wrapping them in a narrative significantly boosts click-through rates.

Format #3: Infographics (The Authority Builder)

Infographics earn the silver medal for reach and engagement—and for good reason.

The Performance Numbers

• 3x reach boost
• 6x save rate
• 2.5x higher comment quality
• Strong authority boost

That save rate is the magic metric. When someone says "I want to reference this later," that's authority in action.

When to Use Infographics

• Data visualization
• Industry analysis
• Complex concepts made simple
• Charts showing trends or comparisons
• Thought leadership backed by numbers

Best Practices

• No personal photos (save those for personal content)
• Maybe include your avatar for authority building
• Focus on data and proof points

Carousels vs. Infographics: How to Decide

Think of it this way:

Carousels tell stories. Infographics prove points.

Walking someone through a process? Use a carousel. Making a powerful data-backed claim? Use an infographic.

Note: AI-powered infographic generation is now possible thanks to new image models like Gemini. This makes creation significantly faster.

Format #4: Video (From King to Strategic Tool)

Video used to be the hype a year ago. Now? It basically died.

What Happened to Video

• The massive reach multiplier disappeared
• Engagement is way down
• No longer prominent on the platform

But Don't Ignore Video Completely

Video remains exceptionally good for authenticity. When people see you speak, we're wired to connect on a human level. It's much easier to build personal relationships through video.

Video Best Practices for 2025

• Make it vertical (more real estate in the feed)
• Keep it short: 60 seconds maximum, 90 seconds absolute limit
• Strong 3-second hook at the beginning
• Ensure 30% completion rate: If viewers drop earlier, you get zero reach
• Open with a punchline
• Always add captions (most people watch on mute)
• Include CTA in the video itself (not just the post—people don't read the attached text)

When to Use Video

• Personal storytelling
• Trust building (middle/bottom of funnel content)
• Personal connection content

When NOT to Use Video

• Complex, in-depth topics (carousels/infographics work better)
• Low-energy talking head monologues
• Top-of-funnel reach content

Format #5: Polls (The Insight Generator)

Polls are in a weird place right now.

What Changed

• Reach is actually up (polls stay visible longer and get more impressions)
• Engagement is significantly down (people don't interact as much anymore)

LinkedIn shows them, but people scroll past. It's likely due to overuse—poll fatigue is real.

If You Use Polls, Do This

• Run them for 7 days for best performance (skip 1-day polls—they get a 70% engagement penalty)
• Use 3 options only (keep it simple)
• Don't include "It depends" or "Other"
• Don't force comments (it rarely works)
• Add poll insights in comments (update with your own commentary on results)
• Don't repeat the same polls

The Strategic Shift

Polls used to be good for reach farming. Now they're better for strategic insight gathering.

Use polls to:

• Research your audience
• Qualify leads
• Test ideas when you genuinely want to know something
• Farm valuable intel

What stopped working: fishing for engagement. People can tell, and they'll scroll right past.

Format #6: LinkedIn Articles and Newsletters (The Renaissance Format)

LinkedIn articles are having a bit of a renaissance, and the data is surprising.

The Numbers

• Good reach multiplier
• Newsletter subscribers are up significantly
• Only 184,000 newsletters exist on LinkedIn (massively underused)

If you already have a newsletter or blog, repurposing it as LinkedIn articles is a great way to show up more often in your followers' feeds.

Best Practices

• Publish bi-weekly (the sweet spot—monthly is too long, weekly gets less reach)
• Consistency is critical (inconsistency is the worst)
• Title length: 7-11 words
• Add a 3-line preheader summary (shows up in "Suggested for You")

Content Types That Work

• Recap newsletters: Summaries and highlights
• Topic newsletters: Deep dives on specific subjects
• Industry newsletters: Position yourself as an authority (especially good for automotive, legal, etc.)

The Reuse Strategy

Every article can become at least 2 snackable posts:

1. One post when you publish the article
2. One reshare a week later with different commentary

Strategic Benefits

• Subscribers are your owned audience within LinkedIn
• Better reach control with newsletter subscribers
• Momentum compounds the longer you publish
• This is a long game for authority building

Pro tip: Don't use hard CTAs at the end—use soft nudges. Include links to YouTube videos or blog posts, but don't be aggressive.

The GAP Content Framework: Putting It All Together

The best LinkedIn strategies use the GAP format: Growth, Authority, and Personal content. These are the three pillars of building a personal brand.

Here's which formats work for which category:

Growth Content

• Carousels ✓
• Text and Image ✓
• Polls (somewhat—more for insights now)

Authority Content

• Carousels ✓
• Infographics ✓✓
• Newsletters ✓
• Video ✓

Personal Content

• Text and Image ✓
• Video ✓✓

The Content Mix Formula

Focus on 1-2 core formats consistently, then mix it up once per week or every two weeks with a different format. That occasional change-up is also where lighter, relatable content fits — if you're weighing it, check should you post memes on LinkedIn for when humor helps and when it hurts.

LinkedIn rewards this approach—you'll notice that different format gets a little boost just because it's new. Your first article, for example, will reach a noticeably different audience.

Choose Your Primary Formats Based on Your Goal

• Primary goal is Growth: Text & Image + Carousels
• Primary goal is Authority: Carousels + Infographics
• Primary goal is Personal Connection: Text & Image + Video

The Golden Ratio

Most of your content should be authority-oriented. The smallest part should be personal (1 post per week is plenty).

Try these mixes:

• 3 Authority + 2 Growth + 1 Personal per week
• 2 Authority + 1 Personal + 2 Growth per week

The Complete LinkedIn Format Hierarchy

For Maximum Reach

Carousels > Infographics > Text and Image > Video

For Minimum Effort, Maximum Impact

Text and Image > Everything Else

For Authority Building

Carousels > Infographics > Newsletters

For Connection and Trust

Video + Text and Image (personal posts)

Content Lifespan Rankings

• Carousels: Longest (up to 2 weeks)
• Videos: 1-2 weeks
• Image posts: 1-5 days
• Polls: Peak in first 48 hours (regardless of duration setting)
• Text-only: Vanishes quickest

Important note: The half-life of all content is longer now than a year ago. You'll regularly see engagement on old posts—something that rarely happened before 2025.

Your Action Plan for This Week

Here's your challenge: Take your best-performing post from 3 months ago, turn it into a carousel, post it, and track the difference.

The algorithm wants format discipline (it helps LinkedIn learn your patterns), but it also rewards variety. Pick your 1-2 core formats that support your strategy and that you can maintain consistently, then spice it up every week or two with something different.

Tools to Make This Easier

Creating multiple format types sounds overwhelming, but modern AI tools make it significantly faster:

• AI Carousel Generator: Instantly creates 7-8 slide carousels from your posts, optimized for storytelling
• AI Infographic Generator: Creates data visualizations in seconds (now possible with new image models)
• AI Image Generation: Creates personal photos of you with custom backgrounds and scenarios
• Media Library: Store and reuse your professional photos across posts
• Quote Cards: Quick visual content creation

These tools can reduce content creation time from hours to literally 30 minutes per week.
