When should you consider making optimisations to a newly launched bid strategy within your Search Ads 360 campaign, assuming that there's no conversion delay?

You should consider making optimizations to a newly launched bid strategy within weeks two to three. This timeframe allows the bid strategy sufficient time to gather enough performance data and learn, but is not so long that potential inefficiencies persist unnecessarily. Week one is generally too soon, as the strategy is still in its initial learning phase and has not accumulated enough data for meaningful adjustments. Waiting until week four or even weeks six to eight might mean missing opportunities to improve performance earlier, as the strategy could be underperforming or overspending for an extended period.
