Here are ten ways to improve your website's Google Lighthouse score:

1. Optimize images by compressing them and using appropriate formats (e.g., JPEG, PNG, WebP).

2. Minimize the use of render-blocking JavaScript and CSS by deferring non-critical scripts and styles.

3. Enable text compression using gzip or Brotli to reduce file sizes and improve load times.

4. Leverage browser caching by setting appropriate cache headers for static assets.

5. Reduce server response time by optimizing server-side code, database queries, and server configurations.

6. Implement lazy loading for images and videos to load them only when they are in the viewport.

7. Use efficient web fonts and limit the number of font variants to minimize the impact on performance.

8. Avoid using excessive DOM elements and optimize your HTML structure for better rendering performance.

9. Ensure your website is mobile-friendly and responsive to provide a good user experience across devices.

10. Implement accessibility best practices, such as using proper heading structure, alt tags for images, and ARIA attributes when necessary.
