LinkedIn’s Algorithm in 2025: How It Works and How B2B Brands Can Win

Introduction: Why LinkedIn Matters for B2B

LinkedIn has evolved from a professional networking site into a powerful B2B marketing platform. Today, over one billion professionals log in each month, including 90 million senior executives and 63 million decision-makers. Yet despite this vast audience, only 1% of users actively create content. That means a tremendous opportunity exists for B2B brands and thought leaders to stand out—if they understand how their content is surfaced and amplified by LinkedIn’s feed algorithm.

Unlike other social networks that chase virality, LinkedIn’s algorithm prioritizes relevance, professionalism, and meaningful engagement. It’s less about sensational headlines and more about delivering genuine value to niche communities. In this guide, you’ll learn:

1. The multi-step process LinkedIn uses to rank posts
2. Which signals—like dwell time and comment quality—matter most
3. How different content formats compare in driving reach and engagement
4. Actionable tactics you can apply today
5. Three detailed case studies showcasing real-world success
6. A forward-looking take on upcoming algorithm trends

By mastering these insights, you’ll be able to craft content that resonates with your professional audience and works with LinkedIn’s AI, rather than against it.

How LinkedIn’s Feed Algorithm Works

At its core, LinkedIn’s feed algorithm is an AI-driven recommendation engine. Each time a user opens their feed, LinkedIn evaluates thousands of potential posts and decides which ones to show, in what order, and to how many people. The process unfolds in three main phases:

1. Quality & Spam Filtering

Before a post even gets a chance to be seen, it’s screened for quality:

1. Spam indicators: Excessive or irrelevant hashtags, mass tagging of people or companies, promotional language without substantive content.
2. Low-quality signals: Poor grammar, repeated words, clickbait headlines (“You won’t believe…”), and links to dubious sites.
3. Human review fallback: If the AI isn’t confident, some posts are flagged for manual moderation.

Result: Spam or poor-quality posts are throttled or suppressed. Only content that passes this filter moves forward.

2. Initial Engagement Test (“Golden Hour”)

Once your post passes the quality check, LinkedIn shows it to a small subset of your connections and followers for around 60 minutes:

1. Engagement signals monitored: Reactions (👍, 💡, 🎉, etc.) Comments (with more weight for in-depth responses) Shares (especially with added commentary) Dwell time (how long users spend reading or viewing)
2. Reactions (👍, 💡, 🎉, etc.)
3. Comments (with more weight for in-depth responses)
4. Shares (especially with added commentary)
5. Dwell time (how long users spend reading or viewing)
6. Quality over quantity: A handful of thoughtful comments can outweigh dozens of generic likes. The algorithm evaluates not just volume, but who is engaging and how deeply.

Result: Posts that earn strong, early engagement are promoted to a larger audience. Those that don’t show promise are quietly deprioritized.

3. Personalized Ranking

For posts that clear the initial hurdle, LinkedIn computes a relevance score for each potential viewer:

Behind the scenes, LinkedIn builds embeddings—vector representations—for each member and each post. The algorithm then “matches” these embeddings to surface content it predicts you’ll care about, even if it comes from outside your immediate network.

Key Algorithm Signals Explained

To optimize your content, focus on these critical signals:

1. Dwell Time

1. Passive measure of interest: how long a user stays on your post.

1. Adjusted by format: 30 seconds on a text post is significant; 30 seconds on a video might be average.

1. Posts with high dwell time get an algorithmic boost—even from users who don’t click like or comment.

2. Meaningful Comments

1. A well-thought comment (≥15 words) signals high value.

1. Comments from industry peers or influencers carry more weight than anonymous reactions.

1. Each comment can be up to 15× more impactful than a like in terms of boosting reach.

3. Early Engagement

1. The first 60 minutes post-publication are crucial.

1. If your post gains traction quickly, LinkedIn exposes it to second- and third-degree connections.

4. Relevance Score

1. Personalized for each viewer based on profile compatibility and predicted actions.

1. LinkedIn continuously retrains its models to align with emerging professional trends and user behavior.

5. Format Signals

1. Native videos and document carousels promote longer sessions on the platform.

1. External links may be deprioritized in favor of in-platform content.

Content Format Comparison

Best Practices to Optimize Your Posts

1. Hook Your Audience Immediately

1. First 1–3 lines are what users see before “...see more.”

1. Start with a surprising stat, provocative question, or bold statement.

2. Encourage Authentic Discussion

1. End with open-ended questions.

1. Invite differing viewpoints: “Do you agree? What’s been your experience?”

1. Steer clear of “engagement bait” (generic pleas for likes/shares).

3. Leverage 3–5 Targeted Hashtags

1. Combine broad (#AI, #Marketing) and niche (#B2BContent, #SupplyChainTech).

1. Keep hashtags relevant to the post content to avoid spam filters.

4. Strategic Tagging

1. Tag only people or companies directly involved.

1. Tags generate notifications and can ignite early engagement—just don’t overdo it.

5. Post When Your Audience Is Active

1. General sweet spots: Tuesday & Wednesday 8–10 AM; Thursday 5–6 PM (audience time zone).

1. Use your LinkedIn Analytics to refine timing based on past performance.

6. Maintain a Consistent Cadence

1. Aim for 2–4 posts per week.

1. Avoid multiple posts in a single day competing for the same audience.

7. Diversify Your Content Mix

1. Alternate between text, images, videos, carousels, and polls.

1. Repurpose long-form assets into shorter feed-friendly snippets.

8. Respond and Engage Quickly

1. Be present in the comments during the first hour after posting.

1. A constructive reply can turn a single comment into a lively thread.

9. Encourage Employee Advocacy

1. Share content internally and invite team members to like, comment, and share.

1. Employee interactions not only boost your post but extend reach to their networks.

10. Iterate Based on Data

1. Monitor impressions, clicks, reactions, comments, and shares.

1. Identify top-performing formats and topics; double down on what works.
