Twitch Reaction Window: 15-60 minutes. Twitch's algorithm responds relatively quickly to engagement spikes during a broadcast.

What this means in practice:

• If your stream produces a chat-velocity spike at minute 30, the algorithm can amplify your browse-page placement within 15-60 minutes
• The amplification continues for the rest of the broadcast if engagement holds
• The boost decays after the broadcast ends — Twitch optimizes for live engagement, not retroactive ranking

Tactical implication:

• Front-load the highest-engagement content in the first 30-60 minutes of a broadcast to trigger the amplification window
• If a moment goes viral mid-stream, lean into it — the next 30-60 minutes are when the algorithm boost will fire
• End-of-stream highlights are less algorithmically valuable than mid-stream peaks because the boost window may not fully fire before broadcast ends

The structural opportunity: Twitch's fast reaction window means a great single broadcast can produce 2-3x normal browse-page placement for the duration. Streamers who engineer high-engagement moments in the first hour benefit most from this mechanic.
