In the Feed, member activity is how members engage with content over time, including the posts they have interacted with.12 LinkedIn considers this activity alongside industry, skills, experience and geography to personalize content as members' interests evolve, including posts from professionals they have never connected with.13 LinkedIn is testing an Interest Picker during sign-up that lets new members select topics to personalize their Feed.3 For creators, engagement counts contribute to how the Feed assesses posts' relevance.2 In March 2026, LinkedIn emphasized authentic participation and said it was reducing engagement bait and repetitive, low-substance posts.13
How the Feed uses engagement over time
To adapt recommendations as members' interests change, the Feed considers both what they have interacted with and content they have or have not reviewed.1 Tim Jurka wrote that if members start exploring a new topic or engaging in certain conversations, the posts they see should reflect that.1 For creators, this creates opportunities for posts to reach people they are not connected to as readers' interests change.12
Turning activity into model inputs
From LinkedIn's research and patents, which may not describe how LinkedIn works today
For Feed retrieval—finding possible posts to show—LinkedIn's engineering team describes converting organized fields into text that large language models, which process text, can use.2 For each member, this text includes a chronologically ordered sequence of posts they previously engaged with.2 The team also groups post engagement counts, such as views, by relative popularity and wraps them in special tokens—markers that identify numerical information—so the model can distinguish the counts from ordinary text.2
