LinkedIn algorithm reset April 2026: posting cadence and format mix
LinkedIn shipped a major algorithm reset April 18 2026. Text-only post reach dropped 30 to 50%. Carousel and document reach held. Native video lifted 20 to 40%. The new posting cadence: 4 posts per week max, format mix 40% carousel + 30% video + 20% text + 10% poll. Engagement window narrowed to 90 minutes.
LinkedIn shipped a major algorithm reset on April 18, 2026. Text-only post reach dropped 30 to 50% across most B2B founder accounts. Carousel and document post reach held flat. Native video lifted 20 to 40%. Polls became the new cheap-engagement vehicle. For B2B founders and social leads who built audiences on text-heavy posting, the reset broke the pattern that worked for 18 months. This post is the new posting cadence and format mix that works post-reset.
By the end you will have the format mix that wins, the posting cadence that does not exhaust the algorithm, the engagement-window discipline that lifts reach 30 to 60%, and the kill-criteria for posts that flop. The full calendar template lives in our 30-Day Social Content Calendar.
Key takeaways. April 18 reset: text-only reach -30-50%, video +20-40%, carousel held. New mix: 40% carousel, 30% video, 20% text, 10% poll. Cadence: 4 posts/week max. Engagement window: 90 min (was 3 hours). Reply rate >80% in first 90 min predicts 5x reach lift. Repurpose top performers monthly.
What changed in the April 2026 algorithm reset?
Three structural changes confirmed by LinkedIn's engineering blog and validated across third-party data from Shield and Buffer. First, the algorithm's content-format weighting shifted toward formats with higher dwell-time-per-impression. Native video and document carousels score 3 to 5x dwell time vs text-only posts. Second, the engagement window narrowed from 3 hours to roughly 90 minutes; posts that do not earn engagement velocity in the first 90 minutes get throttled into limited distribution. Third, comment quality (length, reciprocity, substance) replaced raw comment count as the primary engagement signal.
What does the new format mix look like?
| Format | % of weekly posts | Why it wins post-reset |
|---|---|---|
| Carousel (PDF document) | 40% | 5x dwell time vs text. Held reach in the reset. |
| Native video (15-90 sec) | 30% | 20-40% reach lift. Algorithm prioritizes dwell. |
| Text post | 20% | Down 30-50% reach but still highest-converting for top-of-funnel |
| Poll | 10% | Cheap engagement signal, lifts subsequent post reach |
What is the new posting cadence?
4 posts per week maximum, not 5 to 7. The reset's narrower engagement window means that posts with weak first-90-minute engagement degrade the account's overall distribution score. Posting more often increases the probability of weak posts. Better: post 4 high-conviction times per week, prioritize the engagement window, repurpose top performers monthly. Most B2B founder accounts running 6 to 8 posts per week pre-reset now run 3 to 4 per week and see equal or higher total reach.
How do you use the 90-minute engagement window?
- 1Post at the time your audience is online (LinkedIn analytics shows your peak window). Most B2B audiences peak at 8-10am ET.
- 2Reply to every comment within 90 minutes. Reply rate above 80% in the first 90 minutes predicts a 5x reach lift.
- 3Substantive replies (2-3 sentences) score higher than 'thanks!' or emoji.
- 4Tag 2-3 connections who would meaningfully engage. Do not spam-tag; algorithm penalizes low-relevance tagging.
- 5Re-engage the post at hour 24 with a comment that adds context or a follow-up question.
What does the new content pillar mix look like?
Same 4-pillar structure (authority, proof, education, personality), different format weighting. Authority posts now lean carousel (data-rich, dwell-time-friendly) instead of text. Proof posts run native video with customer voice. Education posts are document carousels (the algorithm's new favorite). Personality posts can stay text but expect 30 to 50% lower reach than a year ago. The pillar weights stay 30/25/25/20.
Most teams reacting to the reset rebalanced too aggressively toward video. Native video helps but cannot carry the calendar. Document carousels are the underrated winner because they ship faster than video and score equivalent dwell time.
What posts should you kill immediately?
- Posts with under 5% comment rate at hour 2 (unlikely to recover, do not boost)
- Posts that earned mostly emoji or one-word comments (algorithm reads as low-quality engagement)
- Posts with reply rate below 50% from the author in the first 90 minutes (algorithm penalty)
- Cross-posted content that already ran on Twitter/X without LinkedIn-native rewrite (low engagement velocity)
- Posts with 4+ outbound links in the first comment (treated as link spam since the reset)
How does this affect B2B founder personal brand strategy?
Founder voice still works, but the format must catch up. Most B2B founders who relied on text-only thought-leadership now run document carousels with the same insight, plus a 60-second video monthly with a contrarian take. The carousel-plus-video pairing maintains reach. Pure text posts run as the 20% layer for high-conviction takes that cannot be visualized.
Pair this calendar with the Social Foundations free course and the 30-Day Social Content Calendar. The course covers pillar mix; the calendar locks the daily prompts. The two together replace ~3 weeks of content-strategy contractor time.
FAQ
Should I delete or repost old text-only posts that performed pre-reset?
Repurpose, do not repost. Convert the top 5 to 10 text posts from the last 6 months into document carousels. Same insight, new format. Most see 60 to 80% of original reach on the carousel re-up.
How long does the engagement window really last?
Around 90 minutes for the algorithm-distribution decision. The post itself can earn engagement for 24 to 72 hours but the distribution decision is locked in the first 90 minutes.
Does this apply to LinkedIn company pages too?
Same algorithm, harder to win. Company pages inherit lower baseline reach. The format mix and cadence still apply but expect 30 to 50% lower reach than equivalent founder personal accounts.
What about LinkedIn newsletters?
Separate distribution mechanism, less affected by the reset. Newsletters still hit subscribers' inboxes. Use them as the long-form home for content that the post format cannot fit.
Should I post on weekends?
B2B audiences engage at 30 to 50% lower rates on weekends. Skip Saturday and Sunday for the 4-per-week cadence. Run the 4 posts Mon-Thu with Friday optional for weekly recap.
