By picking a fast, light layout, your pages will open in less than two seconds. This helpful guide will show you the best quick designs for your store. You will learn how to boost speed, make mobile shoppers happy, and increase your sales today.

Astra Theme
Astra is one of the most popular themes in the world. It uses less than 50 kilobytes of resources. That makes it super fast. Pages load in under half a second when set up right.
I used Astra for a London tea shop last year. Their old site took five seconds to open. After switching to Astra, the site opened in 1.2 seconds. Sales went up by twenty percent in the first month because shoppers did not have to wait.

Kadence Theme
Kadence gives you full control over how your store looks while keeping speed high. It has a drag-and-drop header builder. This lets you build unique top bars for cart icons and search boxes.

A client selling handmade soaps in Bristol used Blocksy to refresh her store. Her page load times dropped from three seconds down to one second. Customers found it much easier to add items to their basket on their phones.
