Platform Algorithm

How Algorithms Affect PR

Organic reach on most platforms has declined steadily as algorithms prioritize paid content and high-engagement posts. A brand's announcement post may reach 2–5% of its followers unless it generates rapid engagement. This makes content quality, posting timing, and format optimization critical for earned social reach.

Platform-Specific Behaviors

TikTok prioritizes watch time and completion rate — short, compelling, loopable content wins. LinkedIn rewards comments over likes and favors text posts with professional insight. Instagram weights saves and shares heavily. X surfaces content based on engagement velocity and network interactions. YouTube optimizes for session time — videos that keep viewers on the platform get recommended.

Algorithm Shifts

Platforms change their algorithms frequently, often without public announcement. A content strategy that works in Q1 may underperform in Q3. Continuous testing, format experimentation, and platform-native content creation are the only sustainable approaches.
