Is anyone experiencing difficulties improving their Pagespeed Insights score for Webflow sites, despite taking measures such as image compression and JS/CSS minification?
TL;DR
- Defer non-essential JavaScript and optimize Webflow interactions by simplifying complex animations.
- Clean up custom code, implement browser caching, use a CDN, and audit third-party scripts.
- Simplify the site structure to manage DOM size effectively.
Improving a Pagespeed Insights score for Webflow sites can sometimes be challenging even after optimizing images and minifying JS/CSS. Here's a structured approach to tackle this issue.
1. Analyze Render-Blocking Resources
- Check Render-Blocking Resources: Use Pagespeed Insights to identify any render-blocking resources. Consider deferring or asynchronously loading non-essential JavaScript files.
- Defer JavaScript: Modify settings to defer JS or use the async attribute where applicable.
2. Optimize Webflow Interactions
- Review Interactions: Some Webflow interactions can cause heavy JavaScript load. Assess and simplify complex animations if possible.
- Limit Use of Lottie Animations: Evaluate the necessity and size of Lottie animations as they could impact loading times.
3. Evaluate Custom Code
- Inspect Custom Code: Look for inefficient or excessive custom code snippets that may hinder performance.
- Remove Unnecessary Code: Clean up and remove code that isn’t essential.
4. Implement Caching Strategies
- Leverage Browser Caching: Ensure that proper caching rules are set up to speed up repeat visits.
- Use a CDN: Employ a Content Delivery Network to decrease load times for users who are geographically distant from your site’s server.
5. Reduce Third-Party Scripts
- Audit Third-Party Scripts: Assess and reduce the number of third-party requests such as fonts, analytics, and widgets.
- Configure Lazy Loading for External Content: Implement lazy loading for third-party content where possible.
6. Monitor for Large DOM Sizes
- Check for a Large DOM: Ensure that your site doesn't have an excessively complicated DOM tree, as it can slow down pages.
- Simplify Structure: If needed, simplify your layout to ensure DOM size remains manageable.
Summary
When your Webflow Pagespeed Insights score struggles despite common optimizations, explore deeper fixes like render-blocking resource management, simplifying interactions, auditing third-party scripts, and managing DOM size. Implementing these strategies can further enhance performance and lead to better scores.
