What "normal" looks like: conversion rates, funnel drop-offs and the numbers to compare yourself against.

Pricing Psychology on the Product Card: What Tests Actually Show

Merchants assume charm pricing and tiered plans are decided by gut feeling, but Shopify's own pricing page shows the anchoring is built into fixed numbers like €24, €69, €289 and €2,100, which is a structural pattern rather than a hunch.

Add to Cart vs Buy Now: Button Microcopy in Published Tests

Merchants keep asking which button label converts better, but the published cart abandonment numbers settle a different question first, which is that the checkout flow around the button matters more than the two or three words printed on it.

When Should the Email Popup Fire? Timing Data

Merchants ask what second to fire the popup, but the actual money question the data answers is whether the email gets delivered at all, since automated email earns $2.87 per send against $0.18 for regular campaigns and none of that matters if the sending setup fails Gmail's 2024 requirements.

Mobile Menu Patterns Across Six Themes: Every Setting Compared

Merchants assume a mega menu is one toggle in the theme editor, but across six Shopify Theme Store themes the mega menu is only exposed as a setting in three of them while the other three bury it in code with no switch at all.

Does Sticky Add to Cart Increase Conversions? Published Tests

Merchants ask for a lift number that applies to their own store, but the only figures that hold up under checking are abandonment averages that swing from 68.70% to 79.53% depending on who ran the survey, which means a sticky bar's real job is closing part of a gap that is already this uneven before it ever loads.

Diary: A Supplements Store and Its Subscription Wall

A merchant looking at a single supplements storefront tends to read its slow checkout as a design failure, but the wider market data settles that the real question is whether the theme underneath passes Core Web Vitals at all, and most stories about conversion never check that.

Guest Checkout vs Forced Accounts: The Published Evidence

Merchants keep assuming forced account creation is a minor speed bump while the published abandonment and form-length data says checkout friction of this kind sits inside a $260 billion recoverable pile, so the usual answer misleads by treating account walls as neutral.

Diary: Auditing a Fashion Store That Converts at 0.8 Percent

A merchant asked why a clothing store stuck at 0.8 percent conversion should care about theme benchmarks, and the answer is that the market data settles what the theme can and cannot fix, which is not what most people assume.

Product Page Teardowns: 10 Real Pages, Scored Line by Line

Merchants assume a slow product page is a design problem, but the real story sits in named settings files like Dawn's main-product.liquid and Horizon's _product-details.liquid, where certain controls simply do not exist yet, no matter how the page looks.

Diary: A Beauty Store Audit, From Quiz to Checkout

This entry settles what a quiz result or a checkout button actually promises a beauty shopper, and why most merchants read a theme's marketing page instead of its code and its live Core Web Vitals numbers.

Conversion Rate by Device: The Published Mobile vs Desktop Gap

Mobile carries three quarters of ecommerce traffic and, depending on whose panel you read, converts either 37% worse than desktop or slightly better. Both findings are real. I lay out the published numbers, then add a live CrUX pull that explains part of the contradiction.
