Improving the mobile score above 90 on Google audits, specifically for the First Contentful Paint (FCP) 3G timing, requires optimizing your Webflow site to ensure faster loading times and better performance. Here are some steps you can take to improve your FCP and overall mobile score:
1. Optimize images: Compress and resize your images to reduce their file size without compromising on quality. Avoid using large images where smaller ones will suffice. Webflow's built-in image optimization feature can help with this.
2. Minify and bundle CSS and JavaScript: Reduce the size and number of requests made by your CSS and JavaScript files by minifying and bundling them together. This helps to improve the loading speed of your site.
3. Enable caching: Utilize browser caching to allow returning visitors to load your site faster by storing certain files locally on their devices. Webflow automatically enables caching on your site, so you don't have to worry about it.
4. Reduce third-party scripts: Evaluate the third-party scripts and services you have integrated into your site and consider removing or optimizing them. Each external script adds a potential delay to your site's loading time.
5. Leverage lazy loading: Implement lazy loading for images and other media on your site. This means that images are only loaded when they come into the user's viewport, rather than all at once. Webflow provides native support for lazy loading.
6. Minimize render-blocking resources: Identify and address any render-blocking resources, such as CSS and JavaScript files, that prevent the browser from rendering the page quickly. Webflow automatically optimizes the loading of CSS and JavaScript files to minimize render-blocking.
7. Use Webflow's responsive design features: Ensure that your site is mobile-responsive and follows best practices for mobile design. Utilize Webflow's breakpoints and responsive design options to optimize the mobile experience.
8. Optimize typography: Use web-safe fonts or consider using a font-loading strategy to prioritize the loading of essential fonts. This helps to avoid any delays caused by custom fonts loading slowly.
9. Test and monitor performance: Regularly test your site's performance using tools like Google PageSpeed Insights, Lighthouse, or Webflow's built-in performance panel. Monitor the changes you make and adjust accordingly to achieve the desired mobile score.
Remember, achieving a score above 90 on Google audits is not always feasible due to factors beyond your control, such as network conditions. However, following these optimization steps can significantly improve your FCP and mobile performance.
