=== Data Transfer and Bandwidth ===
- **Page Load Size**: Analyze the size of resources (HTML, CSS, JavaScript, images) loaded during page loads. Browser developer tools or network analysis tools like Chrome DevTools or Firefox Network Monitor can provide insights.\\
- **Number of HTTP Requests**: Use browser developer tools or network analysis tools to count the number of requests made during page loads. Optimizing resources and combining files can reduce the number of requests.\\
- **Data Caching**: Implement caching strategies to reduce redundant data fetching and improve load times. Monitor cache hit rates and effectiveness to optimize caching policies.

=== Resource Optimization ===
- **Image Optimization**: Check image sizes and formats using tools like ImageOptim or online compression tools. Ensure images are appropriately sized and compressed. \\

=== User Experience ===
- **Responsive Design**: Test the application on various devices and screen sizes to ensure responsiveness. Use browser developer tools or device simulators to simulate different environments. \\
- **Efficient Navigation**: Evaluate the number of clicks required to navigate through the application. User testing and feedback can help identify areas for improvement in navigation efficiency. \\

=== Sustainable Hosting and Practices ===
- **Green Hosting**: Research hosting providers that prioritize renewable energy or carbon offsetting. Check provider documentation or sustainability reports for information on energy practices. \\

=== Development and Build Processes ===
- **Code Quality**: Use code quality tools and linters to ensure clean and efficient code. Regular code reviews can help maintain code quality standards.

=== Monitoring and Reporting ===
- **Real-time Performance Monitoring**: Set up monitoring tools to track performance metrics in real-time. Use alerts and notifications to identify performance issues promptly.

- **Carbon Emission Tracking**: Estimate the carbon footprint of the application based on hosting provider energy usage and user traffic. Use carbon footprint calculators or sustainability metrics provided by hosting services.
