Reports include confidence intervals and key metrics like Conversion value, Conversions, ROAS, CPA, Clicks, Impressions, and CPC. Google recommends six to eight weeks of testing with minimal changes. To set up: Campaigns > Experiments > Custom experiment > Mixed campaign types. This helps answer questions like whether Search plus PMax outperforms Search plus Demand Gen.
