Understanding Platform Physics

Every social platform is a different planet with different gravity. What soars on LinkedIn sinks on Twitter/X. What explodes on short-form video dies in a newsletter. Treating platforms as interchangeable distribution channels is the most expensive mistake in social media marketing.

The physics are simple once you map them. Each platform has three variables: algorithm preference (what the platform rewards with distribution), audience expectation (what users come to the platform for), and content half-life (how long a post stays relevant). Master all three for your primary platform before moving to a second one.

PLATFORM PHYSICS MAP (B2B)
===========================

LINKEDIN
  Algorithm: Rewards engagement velocity in first 60 min
  Audience: Professional growth, industry insight, career
  Half-life: 48-72 hours (long for social)
  Best format: Personal stories, contrarian takes, carousels
  Posting cadence: 3-5x/week
  B2B fit: ★★★★★ — Primary battlefield

TWITTER/X
  Algorithm: Rewards replies and quote tweets
  Audience: News, hot takes, real-time conversation
  Half-life: 4-8 hours (very short)
  Best format: Threads, data drops, bold claims
  Posting cadence: 1-3x/day
  B2B fit: ★★★☆☆ — Good for visibility, weak for pipeline

YOUTUBE (Short + Long)
  Algorithm: Watch time + click-through rate
  Audience: Education, entertainment, how-to
  Half-life: Months to years (evergreen)
  Best format: Tutorials, explainers, behind-the-scenes
  Posting cadence: 1-2x/week (long), 3-5x/week (shorts)
  B2B fit: ★★★★☆ — Builds deep authority over time

NEWSLETTER
  Algorithm: None — direct delivery
  Audience: Curated insight, exclusive analysis
  Half-life: 24-48 hours (email lifespan)
  Best format: Opinionated analysis, proprietary data
  Posting cadence: 1x/week (consistency > frequency)
  B2B fit: ★★★★★ — Owned audience, highest conversion

BUZZ lives in this data. She tracks algorithm changes across every platform weekly and adjusts tactics in real time. My job is strategic: which platforms deserve investment, what business outcome each platform serves, and how social integrates into the broader campaign architecture.

For B2B, the answer is almost always LinkedIn first, newsletter second, everything else as amplification. LinkedIn is where your buyers spend professional attention. The newsletter builds an owned audience you control. Every other platform is a distribution channel for these two primary assets.
