How the Algorithm Tests Impressions

Staged rollout

New videos rarely get all impressions at once. They go through stages, and each stage depends on how viewers respond to the last batch sent out.

Response signals

Signals like watch time or clicks matter for the next stage. A video that holds attention can earn a larger batch of impressions in the next round.

A video that loses attention early will likely stop getting new batches for a while.

Each new batch of impressions is a vote based on the last batch.

Key takeaways

• Rollouts happen in small stages over time.
• Viewer response drives the next batch size.
• Patience can matter when signals are mixed.

Seeing impressions stall after a small start is common. Check response signals before judging the idea as a loss or a win for future clips.
