When would you not want to set a campaign to accelerated ad delivery?

You would not want to set a campaign to accelerated ad delivery when your campaigns are limited by budget because accelerated delivery attempts to show your ads as quickly as possible, which can exhaust your daily budget early in the day. This leaves your ads unable to show for the remainder of the day, missing potential impressions and clicks. Standard delivery, on the other hand, distributes your budget more evenly throughout the day, optimizing for sustained visibility. While profitable campaigns can benefit from accelerated delivery to maximize returns, and a budget set higher than actual spend won't be negatively impacted by accelerated delivery, it's crucial to avoid it when budget constraints are present to ensure your ads run all day and reach your target audience effectively.
