Most agency results pages would not survive these four checks.
A percentage with no baseline, no date range and no source is not evidence. It is a number chosen because it was the most flattering one available, and every agency in this market has a page full of them.
We are not going to fill this page until each case study carries all four, and the client has agreed to be named. If that takes longer, so be it. In the meantime the audit will tell you what we would measure for your business specifically, and references are available the moment you ask.
