The LinkedIn algorithm has matured. The days of chasing simple virality are over. For 2025 and beyond, the platform is doubling down on relevance and expertise. Instead of just showing you what's popular, it aims to show you what's valuable to you and what comes from credible sources.

This means the algorithm now heavily favours content from your first-degree connections and people it identifies as subject matter experts in your field. Think of your feed less as a public square and more as a curated industry journal. The goal is to create meaningful professional conversations, not just to rack up views. Every piece of content is judged on its ability to spark genuine dialogue and demonstrate authority.

Two metrics have become crucial signals of authority: Dwell Time and Saves. Dwell Time is exactly what it sounds like: the amount of time someone spends actively looking at your post without scrolling past it. A quick 'like' is one thing, but when someone stops to read your entire text, swipe through a carousel, or watch a full video, it sends a powerful signal to the algorithm that your content is substantive.

Even more potent is the 'Save' action. When a user saves your post, they're bookmarking it for future reference. This is one of the strongest indicators of high-quality, evergreen content. It tells LinkedIn that your post isn't just an update; it's a resource. Posts with a high number of saves are far more likely to be shown to a wider audience over a longer period.

The first 90 minutes after you publish are critical. This period is often called the 'Golden Hour.' As soon as your post goes live, the algorithm shows it to a small test group of your followers. It then carefully measures the engagement signals from this initial audience.

If the post gets strong early engagement, especially comments and shares, LinkedIn takes it as a sign of quality. The algorithm then pushes the post out to a wider circle of your social graph, including second and third-degree connections. If the initial reaction is weak, the post's reach will be severely limited. That's why sparking conversation immediately is so important.

Not all content formats are created equal. Right now, carousels (shared as PDF documents) are outperforming almost everything else. They excel at increasing Dwell Time because users have to actively click through each slide to consume the content. This sustained interaction is a huge positive signal.

Video can also perform well, but it needs to capture attention within the first three seconds to stop the scroll. Text-only posts are effective for starting conversations, but they have a shorter shelf life. One critical mistake to avoid is placing external links directly in the body of your post. LinkedIn wants to keep users on its platform, so its algorithm actively suppresses posts with outbound links. If you need to share a link, always mention that it's in the first comment.

Time to test your knowledge of the new LinkedIn algorithm.

Mastering these signals is about shifting your mindset from broadcasting to building authority. Create valuable resources, spark genuine conversations, and pay attention to how your audience interacts. The algorithm will reward you for it.
