To increase the Defer parsing of JavaScript score in Webflow, you can follow these steps:

  1. Minimize the use of JavaScript: One of the most effective ways to increase the Defer parsing of JavaScript score is to reduce the overall amount of JavaScript code used on your website. Optimize your code and remove any unnecessary scripts to minimize the file size.

  2. Use async and defer attributes: Webflow allows you to add custom code to your site, including JavaScript. When adding custom JavaScript, make sure to use the async or defer attributes in your script tags. These attributes allow the browser to load and parse JavaScript files asynchronously, meaning it will not block the rendering of the website while the file is being fetched and executed.

  3. Load JavaScript at the bottom of the page: Another way to improve the Defer parsing of JavaScript score is to load the JavaScript files at the bottom of the HTML document, just before the closing tag. This way, the HTML content can load and render first before fetching and executing the JavaScript files.

  4. Utilize Webflow's built-in features: Webflow has built-in features that can help you optimize the loading of JavaScript on your website. For instance, you can enable the "Load JavaScript last" option in your site's settings. This feature automatically moves the JavaScript code to the bottom of the HTML document.

  5. Use external JavaScript files: Instead of embedding JavaScript code directly into your HTML file, consider using external JavaScript files. This allows for caching and reduces the size of your HTML files.

  6. Minify and compress your JavaScript code: Minifying and compressing your JavaScript code can significantly reduce the file size, leading to faster load times. There are various online tools and build processes that you can use to minify and compress your scripts before adding them to your website.

Optimizing the Defer parsing of JavaScript score in Webflow is crucial for improving website performance and user experience. By following these steps, you can significantly enhance the loading speed of your web pages and minimize the impact of JavaScript on the overall load time.
