LinkedIn's AI Changes Content Distribution
LinkedIn has redeployed its feed-distribution logic to prioritize content quality and author expertise using an AI system called 360Brew (reported as a 150‑billion‑parameter model). The platform now weights different engagement signals differently (research cited in the article says a save boosts reach far more than a like and increases follow probability), and LinkedIn’s AI evaluates the text and an account’s topical consistency rather than relying primarily on raw engagement metrics. Third‑party tracking (AuthoredUp) across hundreds of thousands of posts shows most users have seen reach declines since the change, creating a temporary window where publishers who adapt early can gain advantage. The article outlines tactical advice for creators — lead with expertise, narrow topic territory, and reply to comments — to work with the new distribution model.
A major social platform (LinkedIn) changed feed distribution using a large AI model, shifting which signals drive organic reach; this affects how marketers and publishers plan content and distribution strategies.

LinkedIn to Downrank AI‑Generated 'AI‑Slop' Content
LinkedIn announced it will use AI to identify and downrank low-quality AI-generated posts by analysing post structure and engagement patterns. Platform consultant Britta Behrens, speaking on t3n's podcast 'Arbeit in Progress', warns that AI agents are already writing posts and comments to boost reach, but LinkedIn’s changes mean such automation could become a disadvantage. The platform increasingly measures dwell time (whether a post is read fully) and values relevance over raw follower count or likes. Behrens recommends creators focus on impact over impressions, serve a focused target audience, and prioritize meaningful human interaction. The article notes the advice is elaborated in the linked podcast and that the t3n piece was produced with an internal editorial AI tool.
LinkedIn throttles engagement tricks with new ranking system
LinkedIn announced a shift from surfacing content by popularity to ranking posts by relevance. The platform now uses an LLM-based recommendation system, running on GPUs, which analyzes interactions, profile information, and long-term usage to infer user interests and content connections. The system employs embeddings and a two-stage ranking process, potentially surfacing expert content outside a user’s network if thematically relevant. Additionally, LinkedIn is testing an Interest Picker during signup to capture topics of interest (e.g., AI, cybersecurity, leadership, startups) for early personalisation. The update aims to de-emphasise engagement bait and recycled Thought Leadership content in the feed. LinkedIn reports more than 1.3 billion members and emphasizes improved content discovery for both new and existing users.
LinkedIn Cracks Down on 'AI Slop' in Posts
LinkedIn announced measures to limit generic AI-generated content — called "AI Slop" — engagement bait and automated comments. The company says it built a trained detection model with its editorial team that, in early tests, identifies generic AI content with 94% accuracy. Posts flagged as generic will remain visible to an author's network but will be deprioritized by the algorithm. LinkedIn clarified that AI-assisted writing remains permitted, but content must reflect the author's original perspective, expertise or personal experience. The update follows wider platform moves (e.g., Instagram testing an AI Creator label) to promote human-authored and meaningful conversation.
