Facebook quick filter
Filter by ROI desc.
Get the top 5-10 unique ads with the highest ROI.
Pull out the filter window and type those ads in the content filter so you can see only those ad's results.
Click on the customer journey icon.
The bars tell why, the ROI tells how well, the ad tells what, the rev tells how much.
Run these ads again if they are not live. Consider scaling if they are live.
Make note of the ads and see what adsets you have run them against so you can either keep them going, or test a new audience, and insure that you are running an ad with the intent that matches the customer journey bar results and the cold/warm traffic that the adset represents.
Additionally, click on the benchmark icon for that row. Pick the attribution model / intent, and you vs. yourself benchmark. See how this row's performance compares against your past.
