LinkedIn Just Changed Its Algorithm Again — Here's What New York B2B Companies Need to Know

If your LinkedIn content stopped performing the way it used to sometime in the second half of 2025, you're not imagining it. Views are down 50% year-over-year.

This post breaks down exactly what changed, what the new algorithm actually rewards, and what New York B2B companies need to do differently to stay visible on the platform that still dominates professional lead generation.
