The four tabs
The tabs are a hierarchy: Channels, Campaigns, Ad sets, Ads. Ticking rows on one tab narrows the tabs below it. Select two channels, move to Campaigns, and you are already looking at just those channels’ campaigns — no waiting, because the whole report arrived in one pass. Selections never affect the tab above, so the level you are reading always has trustworthy totals.Changing the model
The model selector changes every number in the report. A campaign that looks profitable on last touch can look mediocre on linear, and neither is a mistake — they answer different questions.Reading ROAS
ROAS here divides attributed revenue by the spend Soran knows about, so it is only as complete as your connected ad accounts. A channel with revenue and no spend is usually an unconnected account rather than free traffic.Reports overview
