๐Ÿฆ„ 4.7% more subscriptions from one checkout change

Hey again ๐Ÿ‘‹

Some things get set and never revisited. Site search, checkout currency defaults, whether the AI is the designer or just the builder.

Here are my three picks this week: the search paradox sending users to Google, what actually separates genUI from vibe coding, and what Stripe found across 1.5M subscription checkouts.

The three picks I'd send to a teammate:

Build: Check your site search against words users actually use, not your own vocabulary

Shape: Ask whether the AI decided what to build or you did before evaluating the output

Ship: See what Stripe found when they tested local currency across 1.5M subscription checkouts

Top 3 this week ๐Ÿ‘‡

Build: The Site-Search Paradox: Why The Big Box Always Wins โ†—

Users search with their words. Your site only knows yours.

Why: 50% of users hit search immediately, then leave when it returns nothing for their vocabulary rather than yours.

Adopt: Search your site for a synonym of your top product category and count how many results come back empty.

Shape: GenUI vs. Vibe Coding: Who's Designing? โ†—

GenUI is the AI's design call. Vibe coding executes yours.

Why: Who initiated the design determines what quality means: the AI's judgment call, or how well it executed yours.

Adopt: Ask whether the AI decided what to build or you did. The failure modes are completely different.

Ship: Testing the Impact of Adaptive Pricing Across 1.5M Subscription Checkout Sessions โ†—

Stripe tested local currency on 1.5M checkouts. Conversion up 4.7%.

Why: In 2025, 80% of subscriptions still charged in the seller's currency. Local pricing lifted LTV per session by 5.4%.

Adopt: Check whether your checkout defaults to your base currency for international visitors.
