Look at the date range before the logo.

Almost every glowing network case study reports a window that ends in November or December. Q4 RPMs run 40-80% above the summer trough on the exact same site, same setup. Pick a December-ending window and any competent network looks like a genius.

🚩 Hidden variable: the seasonality curve. Display CPMs follow advertiser budgets — peaking at year-end, cratering in January-February. A 90-day case study starting in October is measuring the calendar, not the network.

The only honest case study spans a full 12 months or compares the same month year-over-year.

Not saying the case study is fake — saying a Q4-shaped timeframe flatters everyone, and they chose it on purpose.
