How can I improve the visual stability of my website?

Topic summary

A Shopify store owner is experiencing poor visual stability scores, which indicate layout shifts during page loading that negatively impact user experience.

Root Cause & Diagnosis:

  • The issue stems from elements loading at different speeds, causing content to shift unexpectedly
  • Shopify’s Web Performance Dashboard can identify specific problematic elements

Recommended Solutions:

  • Image optimization: Resize images to appropriate dimensions before uploading (current images at 2048 x 3072 pixels may be too large), implement lazy loading for off-screen images
  • Reserve space: Use CSS width/height properties to allocate space for slow-loading elements like ads or embedded content
  • Font optimization: Use web fonts with proper fallbacks to ensure consistent loading
  • Theme review: Check theme code (especially theme.liquid file) for scripts causing shifts
  • Third-party apps: Temporarily disable recently installed apps to test if they’re contributing to instability

Current Status:

  • The original poster received code snippets from Shopify support (shown in attached images) but doesn’t know where to implement them
  • Multiple users are now seeking guidance on proper code placement and whether additional steps are needed before implementation
  • The discussion remains open with unanswered technical questions about code integration

Hi,

my shopify Account shows that my website visual stability is poor. How can I optimize it?

Hello @sahar5 ,

A poor visual stability score in your Shopify account indicates unexpected layout shifts while your website loads. This can create a frustrating user experience. Here are some strategies to optimize your website’s visual stability and improve your score:

Identify the Culprits:

  • Shopify Web Performance Dashboard: Use the Shopify Web Performance Dashboard to get more details about what’s causing the layout shifts. It might highlight specific elements like images or ads that are causing the issue.

Image Optimization:

  • Resize Images: Ensure all images used on your website are resized to their appropriate dimensions before uploading them to Shopify. This reduces the file size and minimizes the time it takes for them to load.
  • Consider Lazy Loading: Shopify themes might offer built-in lazy loading functionality or allow you to implement it with JavaScript. Lazy loading delays the loading of images outside the viewport (what the user sees without scrolling) until they are needed, improving initial page load speed.

Other Techniques:

  • Reserve Space for Elements: If you have elements that take a long time to load (like ads or embedded content), use CSS techniques like width and height properties to reserve space for them in the layout. This prevents other content from shifting around while they load.
  • Minimize Use of Flashing Content: Avoid using elements that blink or change size rapidly, as this can be visually distracting and contribute to instability.
  • Font Optimization: Use web fonts with proper fallbacks to ensure fonts load consistently and don’t cause layout shifts.

Theme Considerations:

  • Theme Code Review: If you’re comfortable with code, review your theme code (especially the theme.liquid file) for any scripts or functionalities that might be causing layout shifts.

Third-party Apps:

  • Temporarily Disable Apps: If you have recently installed any third-party apps, try temporarily disabling them to see if the visual stability improves. Some apps might inject scripts or modify the layout in ways that can cause instability.

    • Prioritize Viewport Content: Focus on optimizing the initial content that loads within the user’s viewport for the best user experience.
    • Test and Monitor: After implementing changes, test your website on different devices and browsers to ensure they render correctly. Use tools like Google PageSpeed Insights to monitor your visual stability score.

    By implementing these strategies and tools, you can improve your website’s visual stability on Shopify, leading to a better user experience and potentially higher search engine rankings.

Thank you. The pictures i uploaded are the size: 2048 x 3072 Pixels is that ok? in Shopify support service they say I Should add these Codes, but I don’t know where i Should add these codes? Will they help?

Can someone help with these codes? where to put them? is there anything else need adding in before coding?
