LinkedIn's New 360Brew AI Algorithm: Why Your Reach Dropped 47% and What to Do
LinkedIn replaced its algorithm with a 150B-parameter AI model called 360Brew. Most people haven't noticed. They've just watched their reach quietly disappear.
Including mine.
My reach had been horrible lately, so I went deep on the data. Here's everything I found.

The Damage: What the Data Shows
The decline is real and it's widespread:
Median impressions dropped from 1,211 to 636 per post. That's a 47% decline in 12 months.
98% of users lost reach. The top 2% gained it. Top creators went from 15% of feed share to 31%. Regular users dropped from 57% to 28%.
Company pages now reach just 1.6% of their followers. Personal profiles get 561% more reach posting the exact same content.
Read that last one again. If you're still posting from your company page instead of your personal profile, you're getting one-sixth the distribution for free.
What Actually Changed
The old algorithm counted signals. The new one reads your content like an editor, cross-references it against your profile, and decides whether you actually know what you're talking about.
Profile says "growth marketer" but you're posting about crypto?Suppressed.
Profile matches your content? Amplified.
360Brew takes roughly 90 days to map your expertise. Topic-hopping kills you. The algorithm is built to reward people who treat their LinkedIn profile like a publication with a defined subject area.

The New Engagement Hierarchy
Not all engagement is equal anymore. Here's how the algorithm now weights different signals:
Signal | Algorithmic Weight |
|---|---|
1 save | Equivalent to 5 likes |
1 meaningful comment (15+ words) | Equivalent to 15 likes |
DM share | Second strongest signal overall |
61+ seconds dwell time | 15.6% engagement rate vs. 1.2% at under 3 seconds |
High likes + low dwell time | Flagged as engagement bait |
This is the biggest shift. The algorithm now punishes surface-level engagement. Those "Great post!" comments from your engagement pod? They're actively hurting your reach.
What Formats Are Working in 2026
Carousels are the clear winner: 278% more engagement than video and 596% more than text-only. The sweet spot is 8 to 10 slides.
Polls are massively underused. They make up only 1.4% of content on the platform but have the highest reach multiplier at 1.64x.
Short vertical video (30 to 90 seconds) is up 80% in reach.
LinkedIn Newsletters are up 48% in reach, and Google indexes them. They land directly in your connections' inboxes. This is the sleeper weapon almost nobody is using yet. If you're already writing long-form LinkedIn posts, converting them into a newsletter is the highest-leverage move you can make on the platform right now.
Text-only posts are now the weakest format with a 0.88x reach multiplier.
What Gets You Penalized
Avoid these:
Engagement pods: 97% detection accuracy. Shadow bans last 60 to 90 days.
External links in the post body: -25 to 40% reach. Put links in the first comment instead.
AI-generated content: 45% fewer interactions than human-written posts.
More than 5 hashtags, tagging 10 or more people, or posting more than once per day.
The Golden Window: Timing and Post Mechanics
The first 60 to 90 minutes decide 70% of your post's total reach.
Replying to comments within 30 minutes generates 64% more total comments.
Posts can now circulate for 2 to 3 weeks. Saves received 24 to 72 hours after posting perform 4 to 6x better.
Post length sweet spot: 1,300 to 1,900 characters. Under 500 characters gets flagged as low-effort and receives -35% reach.

The Takeaway
LinkedIn stopped rewarding volume and started rewarding substance. The creators treating their profile like a publication are exactly who 360Brew is designed to amplify.
Everyone else is shouting into an algorithm that now understands precisely how empty the shouting is.
When Organic Reach Shrinks, Outbound Fills the Gap
Organic reach being cut in half doesn't mean LinkedIn is less valuable. It means the way you reach the right people has to change.
Valley is the LinkedIn outreach engine built for exactly this environment. Instead of waiting for your posts to reach the right buyers, Valley proactively identifies warm leads (profile viewers, post engagers, website visitors, competitor signals), qualifies them against your ICP, and sends personalized outreach automatically.
Real campaigns average 3x better results than standard outreach. If organic reach is shrinking, outbound is how you stay in front of the right people.
Frequently Asked Questions
What is LinkedIn's 360Brew algorithm?
360Brew is LinkedIn's new 150-billion-parameter AI model that replaced the platform's previous ranking algorithm. Unlike the old system that counted engagement signals, 360Brew reads content like an editor, cross-references it against your profile, and determines whether you have genuine expertise in the topics you post about. It rewards focused, consistent subject-matter posting and penalizes topic-hopping, AI-generated content, and surface-level engagement.
Why did my LinkedIn reach drop in 2026?
Median impressions on LinkedIn dropped 47% in 12 months following the 360Brew rollout. 98% of users lost reach while the top 2% of creators gained it significantly. The algorithm now prioritizes expertise signals, content-profile alignment, and deep engagement (saves, meaningful comments, dwell time) over volume and simple likes.
Does posting from a company page hurt your reach on LinkedIn?
Yes, significantly. Company pages now reach only 1.6% of their followers. Personal profiles get 561% more reach posting the exact same content. If you're relying on a company page for LinkedIn distribution, you're getting roughly one-sixth the reach you'd get from a personal profile for free.
What content formats get the most reach on LinkedIn in 2026?
Carousels perform best with 278% more engagement than video and 596% more than text-only. The optimal carousel length is 8 to 10 slides. Polls have the highest reach multiplier at 1.64x. Short vertical video (30 to 90 seconds) is up 80%. LinkedIn Newsletters are up 48% in reach and are indexed by Google. Text-only posts are now the weakest format.
How do LinkedIn engagement pods affect reach under 360Brew?
360Brew detects engagement pods with 97% accuracy. If caught, your account receives a shadow ban that lasts 60 to 90 days. Inauthentic short comments (under 15 words) from pod activity also carry reduced algorithmic weight compared to genuine, substantive comments.
