Which report can best evaluate the overall performance of multiple campaigns at a glance?

The best report type for evaluating the overall performance of multiple campaigns at a glance is a joined report. Joined reports allow users to combine multiple report types into one report, enabling a comprehensive view of data from different sources. This is particularly useful for campaigns where you may want to analyze various metrics (e.g., conversions, engagement, spend) from different campaigns side by side.

In a joined report, you can display data from multiple report types or objects together, which gives you a powerful tool for comparing and analyzing performances across different campaigns at once. This format makes it easier to spot trends and assess overall effectiveness without needing to switch between separate reports.

Tabular reports provide data in a simple list format, summary reports offer grouped data typically with subtotals, and matrix reports allow data to be summarized in two dimensions but do not provide the same level of flexibility for combining multiple datasets as joined reports do.
