Relevance and trust before fill. No-fill is success. Fail open.
- Optimize for relevance and trust before fill rate.
- No-fill is a successful result.
- Start with low frequency.
- Never render consecutively.
- Raise frequency only after trust and retention hold.
- Measure eligible requests, fill, no-fill reasons, qualified clicks, conversions, complaints or dismissals, task completion, session completion, and holdout retention.
- Decision target: 150ms retrieval/rank budget; 400ms total handler budget.
- Never reserve blank UI while waiting.
- Fail open on no-fill, timeout, malformed response, or network error.
