Which of the following is a benefit of selecting automatic placements?

Choosing automatic placements offers a significant advantage in terms of ad delivery efficiency. When advertisers select automatic placements, they allow Meta's algorithms to determine the best platforms and placements for their ads based on performance data and user engagement patterns. This means the ads can be shown in various locations where they are most likely to achieve optimal visibility and engagement, which can lead to more conversions and improved overall campaign performance.

This approach takes advantage of machine learning capabilities, continuously analyzing and optimizing placements based on real-time data. As a result, advertisers benefit from a broader reach and potentially lower costs per conversion since their budget is being allocated intelligently across multiple placements that drive the best results.

The other options do not highlight the benefits of automatic placements accurately. For instance, fixed budget allocation does not relate specifically to the automatic nature of placements; engagement rates are not reduced by automatic placements but rather can potentially improve; and audience targeting options are actually broader when using automatic placements, not limited. Automatic placements enhance the likelihood of finding the right audience in the right context for an ad.
