The "Depth Score" Algorithm

The Update: LinkedIn now uses an "Authenticity and Depth Score" to rank content. The algorithm identifies your "Topic DNA"—the subjects you consistently talk about with authority—and prioritizes your posts for users interested in those specific niches, regardless of whether they follow you.

• Impact Media Insight: Consistency is key. If you are a finance expert, post consistently about finance. If you jump between random topics, the algorithm won't know where to place you, and your reach will drop.

Document Posts (PDF Carousels) are King

The Update: Multi-page PDF carousels are currently the highest-performing format on the platform, seeing nearly 3x more engagement than standard videos and 6x more than text-only posts. This is because they maximize "Dwell Time" (the time a user spends on your post).

• Impact Media Insight: For PNG businesses, use this format for "How-To" guides, industry reports, or step-by-step service explainers. Keep them between 5–10 slides for maximum impact.

The Death of the "Link in First Comment"

The Update: For years, users put links in the first comment to avoid reach penalties. As of early 2026, LinkedIn’s AI now detects this behavior and applies a penalty regardless. Posts with external links (even in comments) see approximately 40–60% less reach.

• Impact Media Insight: To drive traffic to your website, focus on "Native Content" first. Provide the value directly on LinkedIn, and only use links sparingly or when a user explicitly asks for more information in a DM.

AI-Powered "Thought Leadership" Detection

The Update: LinkedIn has integrated Large Language Models (LLMs) into its feed retrieval. It can now distinguish between generic AI-generated "fluff" and original human insights. "Recycled" thought leadership—content that repeats common knowledge without a new perspective—is being actively down ranked.

​

• Impact Media Insight: Avoid using ChatGPT to write generic "5 tips for success" posts. Instead, share a specific story about a project you did in Port Moresby or a lesson you learned running your agency. The more specific and local the story, the higher it will rank.
