• Focus on Performance
  Keep your customizations efficient by:

  • Compressing images
  • Enabling lazy loading
  • Writing clean, efficient code
  • Reducing reliance on third-party scripts

If your store requires more complex changes, consider working with experts like Codersy to ensure everything runs smoothly while meeting your business needs.

Boosting Page Load Speed

Page load speed is crucial for conversions and user experience on Shopify Plus stores. Here’s how you can improve it:

Optimization Area	Implementation Method	Impact

For even better results, think about advanced solutions like headless commerce.

Using Headless Commerce for Better Performance

Shopify Plus offers robust API tools, making headless commerce a practical choice for stores aiming to improve performance and user experience. This approach separates the front-end and back-end, offering benefits such as:

• Faster Page Transitions: Content loads dynamically without reloading the entire page.
• Custom User Interfaces: Design interfaces optimized for specific devices.

Stores adopting headless commerce on Shopify Plus have seen load times improve by up to 30% and conversion rates increase by 20% ^[2]. However, regular maintenance is key to keeping these benefits over time.

Keeping Themes Updated and Secure

Routine updates and maintenance are essential for both performance and security. Follow these steps:

1. Track Performance Metrics

Use Shopify analytics to monitor key metrics like TTFB (Time to First Byte) and FCP (First Contentful Paint). Regularly update your theme to stay compatible with Shopify Plus's newest features ^[1].

2. Refine Your Code

Review and clean up your theme's code periodically. Remove outdated functions and align with current best practices to enhance efficiency ^[3].

"Limiting third-party apps and JavaScript is crucial for maintaining optimal performance. Every additional script may slow your store's load time and impact user experience ^[3]."

For complex optimizations, consider hiring developers experienced in Shopify Plus. They can help fine-tune your store’s performance while ensuring customizations align with your business needs.
