• Better Google PageSpeed scores and Core Web Vitals metrics

These improvements benefit mobile and desktop user experiences.

2 Effective Mobile-Focused Strategies for Magento Speed Optimization

1. Consider Lightweight Design

Magento websites often struggle with performance due to complex designs and media-heavy content. To improve mobile performance:

1. Simplify layout structure.
2. Remove resource-intensive elements.
3. Optimize images for mobile viewing.
4. Reduce carousels, pop-ups, and excessive DOM elements.

The Hyvä theme, designed for Magento 2.4.x, reduces JavaScript dependencies. Compared to standard Luma themes, it is an excellent choice for mobile optimization.
