Most agency case studies are unfalsifiable. A percentage with no period, no currency and no conversion action named is not evidence — it is decoration. Every number below was re-pulled from the account that produced it.
These are the 17 Google Ads results that survived that re-pull. Each row links to the full page, which states its period, its currency, the exact conversion action counted, and anything that moved the wrong way.
