How to Improve Google Lighthouse Score

-

 Improving the score of your website, on Google Lighthouse is essential as it enhances performance, accessibility and overall user experience. Google Lighthouse is an automated open source tool that measures web page performance and provides suggestions for optimization. A higher score not improves search engine rankings. Also ensures a smoother user experience. In this guide we will explore strategies to increase your Google Lighthouse score.



Optimizing Images:

 to the size of a webpage. You can use techniques like image compression to reduce file sizes without compromising quality. Consider utilizing image formats such, as WebP which offer compression capabilities. Moreover you can make use of images and lazy loading to ensure that images are loaded when they appear within the users visible area.


Minimizing HTTP Requests:

Reducing the number of HTTP requests helps in speeding up page loading times. You can achieve this by combining CSS and JavaScript files into files and utilizing CSS sprites to merge multiple images into one. This approach minimizes the round trips needed to load a page resulting in loading times and ultimately boosting your Lighthouse score.


Enabling Browser Caching:

Take advantage of browser caching by storing resources on the users device.

To make your website load faster for returning visitors you can utilize the browsers cache to retrieve resources of sending requests to the server. Make sure to set an expiration date for your resources so that users always get the up, to date versions when needed.

Implement Gzip Compression:

To reduce the size of files transferred over the network enable Gzip compression on your web server. This is particularly effective for compressing text based resources like HTML, CSS and JavaScript resulting in load times. By doing this not will you improve your Lighthouse score. Also enhance the overall user experience especially for those, with slower internet connections.

Prioritize Critical CSS and JavaScript:

Improve your rendering path by prioritizing and delivering the essential CSS and JavaScript required for the initial page load. You can achieve this by including CSS in the HTML code to eliminate any render blocking resources. Additionally defer loading essential scripts asynchronously to ensure that users see meaningful content quickly. This approach positively impacts performance metrics. Contributes to a Lighthouse score.

Address Render-Blocking Resources:

Identify any render blocking resources that may delay page rendering and take steps to address them effectively. By loading essential scripts asynchronously or after the initial page load you can prevent them from hindering the rendering of crucial content.

This approach enhances the perceived performance of your website. Has an influence, on your Lighthouse score.

Ensure Responsive Design:

Make sure your website is optimized for devices and screen sizes to ensure an user friendly experience across desktops, tablets and smartphones. Google Lighthouse evaluates how responsive your site is and having a optimized design can have an impact on your score.

Enhance Server Response Time:

Improve server response time by optimizing your server infrastructure, database queries and backend code. A faster server response time contributes to page loading. Utilize content delivery networks (CDNs) to distribute content globally reducing the distance between users and your servers which further improves response times.

Audit and Optimize Third-Party Scripts:

Having a number or optimized external scripts can significantly affect the performance of your pages. Consider loading essential third party resources asynchronously only when necessary. This ensures that the performance of your site is not overly reliant on dependencies.



Ensure Accessibility Compliance:

Take into account accessibility issues to enhance the user experience for all visitors including those, with disabilities. Use HTML, provide text for images and ensure proper document structure.

Make sure to conduct accessibility audits and take action on any issues that tools like Google Lighthouse identify. This will help improve the inclusivity of your website and boost its score, in this metric.
