Mistake 1: Stale Metadata Across Streams. Reusing the same generic title, tags, and category for every broadcast.

The pattern: streamer sets up Twitch panel with a generic title ("[Streamer Name] streaming!"). Forgets to update for individual broadcasts. Tags are 3 generic ones set when they first set up the channel a year ago. Category drifts because the streamer doesn't update it when activities change mid-stream.

The cost:

• Discovery suffers — the algorithm doesn't know what's actually happening on the stream
• Browse-page sub-filtering misses you because tags don't match user search behavior
• The algorithm reads the metadata staleness as a signal of low effort, which feeds into ranking

The fix: 90 seconds per stream to update metadata. Title that names what's specifically happening today. Tags that match the activity. Category that matches the content. Update mid-stream when you switch activities.

The discipline: add metadata update to your pre-stream checklist alongside testing audio and adjusting lighting. Make it routine. The 90 seconds compounds across hundreds of broadcasts.
