A faster site load time improves user experience, reduces bounce rates, and increases conversions. To ensure your single product page loads quickly and provides a smooth user experience, follow these best practices:

Image Optimization

• Lazy Loading: Ensure lazy loading is enabled to defer offscreen images.

• Ensure Proper Image Sizes: Adjust the main product image size to fit the screen’s visual ratio for optimal viewing display. After setup a size, you may need to regenerate your thumbnails with Regenerate Thumbnails plugin.

• Optimize Thumbnail Sizes: Set appropriate dimensions for product thumbnail images.

• Use WebP Format: Encourage WebP image usage or convert images using plugins like Performance Lab or Modern Image Formats.
• Ensure Proper Image Attributes: Make sure all image tags on the single product page include width and height attributes to prevent layout shifts.
• Optimize Video Display: Use a lightbox for product videos to improve loading speed and user experience.

CSS & JavaScript Optimization

• Minify CSS to reduce file size.
• Combine CSS files to decrease the number of requests.
• Minify JavaScript to remove unnecessary characters and speed up execution.
• Combine JavaScript files to reduce the number of HTTP requests.
• Minify HTML for a more efficient page structure.
• Remove Unnecessary JS & CSS files that are not required on the single product page.

Performance Enhancements

• Load Product Gallery on Visible Viewport: Ensure the product gallery only loads when it comes into view.

• Dequeue Unnecessary CSS Files: Add a handler to remove unwanted CSS files that slow down loading.

• Dequeue Unnecessary JavaScript Files: Add a handler to remove redundant JavaScript files.

Implementing these optimizations can significantly improve the speed of your single product page, reduce page load time, and improve customers’ overall shopping experience.
