Your reporting covers four levels:
Campaign level: total spend, revenue, ROAS, CPA, conversions, impressions, and reach
Creator level: ROAS, CPA, spend, and content performance per creator
Content level: spend, impressions, reach, and engagement rate per piece
Time series: daily or monthly performance trends
Note: post level ROAS is not broken out, because Meta aggregates conversion data at ad and ad set level, not per individual creative.
