The lesson
Open a case study with two result numbers beside the actual ad, so the reader sees the proof and the thing that produced it together.
The headline "Multiplacement targeting builds efficiencies and delivers qualified leads" sits over two large figures, 68% (more efficient CPA two weeks after implementing multi-placement) and 40% (sales-qualified accounts sourced from Reddit that converted into opportunities), with a source line. Beside them is the real Huntress promoted post, "Is Your Data Living Up To Its Potential?". Below are Background, Strategy and Outcome sections, then a quote from Kyle Munson.
Don't copy the platform's own metrics as if they are yours; use numbers you can source. Keep the top block: two defined results, a source line and the real creative in the first screen.
