Web performance
What changes when your store loads better on mobile
A Tiendanube case study shows why it helps to measure both what customers see first and what happens on the way to checkout.
Try the page your customer actually lands on
Someone searching for a product might arrive from Google straight onto a product page, on a phone with an unreliable connection. Open that page yourself and notice when the main photo appears, whether you can see the price, and whether the layout jumps while you choose a variant. Repeat the check on a category page and in the cart.
What Tiendanube observed
The team at Nuvemshop, known as Tiendanube in Spanish-speaking Latin America, changed when key storefront images loaded and made other performance improvements. In a case study published on web.dev in June 2026, the team compared the same group of Brazilian stores active in January 2025 and January 2026.
Among mobile visits from organic Google search, the rate of sessions ending in a paid order rose by 8.9% in relative terms. The comparison describes what happened in that group over the period, with several changes happening together. It gives you a reason to measure your own checkout journey.
Pick an improvement you can measure
Start with a product page that gets traffic and use PageSpeed Insights to help diagnose it. If the main photo takes a while to appear, check its file size and when it starts downloading. Try the journey on a real phone before and after making a change.
Track an outcome that matters to the business, such as how many visits lead to adding a product to the cart or completing a purchase. Compare similar periods and account for changes in prices, promotions, or campaigns when you read the result.
