Understand and Beat the LinkedIn Algorithm

Act as a LinkedIn algorithm expert. I want to understand how the LinkedIn algorithm works so I can increase the reach of my posts organically. Explain: how the algorithm decides who sees a post in the first 60 minutes, what post formats are currently getting the most reach, which behaviours increase or decrease distribution, the role of dwell time, comments, and shares vs reactions, and the top 5 things I should do differently in my posting strategy starting today based on how the algorithm currently works.
