An auto advertiser notices that its consideration campaign meets its goal, but there are issues with the campaign delivering. Which are the two actions that can be implemented below to help improve delivery?

When a campaign struggles with delivery despite meeting its goal, it indicates that the ad system is having difficulty finding enough relevant users to show the ads to within the given constraints. Refining targeting relevance helps by ensuring the ads are shown to users most likely to engage, which can improve delivery by making the campaign more attractive to the ad system. Expanding targeting increases the potential audience size, giving the ad system more opportunities to deliver impressions. Increasing the minimum or maximum bid might help if the bids are too low to be competitive, but the problem states the campaign meets its goal, suggesting bid levels aren't the primary issue. Switching to auto bid delegates bidding strategy to the platform, which might or might not improve delivery depending on the specific campaign context and platform algorithms.
