The most expensive leak in most businesses is the last step, between a visit already paid for and a booking that never happens: the slow page, the abandoned form, the call that goes to voicemail. This line covers the science of closing that gap honestly, without the dark patterns that borrow a sale from tomorrow.

The Peeking Problem: Why Checking Your A/B Test Dashboard Early Lies to You

A standard A/B test promises a 5 percent false-positive rate only if you look once. Watching it run and stopping when it looks good quietly pushes that rate far higher. The evidence, the mechanism, and the fix that actually holds.

Why Most A/B Tests Are Wrong Before They Start: Sample Ratio Mismatch, Explained

Sample Ratio Mismatch is a setup failure, not a result. When it fires, a winning A/B test is invalid no matter how large the observed lift. Here is what it is, why roughly 6% of production tests trip it, and why the check has to come before you trust the number.

The 12-Field Checkout: What Baymard's Usability Corpus Says a Minimal Funnel Looks Like

Baymard's finding that the average site can gain about 35 percent conversion from checkout-usability fixes is not a slogan.
