What does "Vendors" refer to in the campaign reporting?

The selected answer option is correct because "Vendors" in campaign reporting refers to which brands the report will include. In the context of the report, the term "vendors" typically designates the specific brands or sellers whose campaign data is being analyzed. By selecting the appropriate vendors, advertisers can tailor the report to focus on specific brands or product offerings within the campaign, allowing for a more granular view of performance. This enables advertisers to assess the effectiveness of their campaigns for different brands they are promoting or collaborating with, helping them make more informed decisions and optimizations based on the performance of each vendor.
