An advertiser wants an overview of all their campaigns' performance. At which level should they view the results?

Viewing results at the ad account level provides the most comprehensive overview of all campaigns' performance. This level aggregates data from all campaigns, ad sets, and ads within the account, allowing the advertiser to assess overall performance metrics such as total spending, reach, impressions, and conversions across all campaigns.

By contrast, the other levels focus on more specific segments of advertising:

• At the campaign level, insights are limited to the particular performance of that individual campaign, which might not reflect the broader performance trends that the advertiser is interested in.

• The ad set level narrows the focus even further to the performance metrics of specific groups of ads within a campaign, which is useful for optimization but does not provide a holistic view.

• The ad level allows for analysis of individual ads but misses out on capturing data from the entire campaign or account, making it unsuitable for assessing overall performance.

Thus, for a complete picture across multiple campaigns, examining the ad account level is the most effective approach.
