An advertiser is running a campaign with automatic bidding that's been live for 24 hours. However, the campaign is not delivering conversions yet. Which optimization tactic should they apply?

The selected answer is correct because Pinterest’s automatic bidding algorithm requires a "learning phase" to collect enough data and signals to optimize delivery toward potential converters. Since the campaign has only been live for 24 hours, the system has not yet gathered sufficient performance history to make informed bidding decisions; waiting for a minimum of seven days allows the algorithm to stabilize and exit this initial learning period without being disrupted by premature manual adjustments that could reset the optimization process.
