What constitutes a high performing website?
High performance for a website involves several key factors that collectively ensure fast loading times, smooth user experiences, and efficient resource usage.
Here are the primary components that constitute high performance:
1. Page Load Speed
- Time to First Byte (TTFB): The time it takes for a user’s browser to receive the first byte of data from your server. A TTFB under 200 milliseconds is generally considered good
- Full Page Load Time: The time it takes for the entire page to load completely. Ideally, this should be under 3 seconds
2. Core Web Vitals
- Largest Contentful Paint (LCP): Measures loading performance. LCP should occur within 2.5 seconds of when the page first starts loading
- First Input Delay (FID): Measures interactivity. FID should be less than 100 milliseconds
- Cumulative Layout Shift (CLS): Measures visual stability. CLS should be less than 0.1
3. Mobile Performance
- Responsive Design: Ensures that your website adapts to various screen sizes and devices
- Mobile Load Time: Optimised performance for mobile devices, often through techniques like image compression and minimising the use of large JavaScript files
4. Efficient Coding and Resource Management
- Minification: Reducing the size of HTML, CSS, and JavaScript files by removing unnecessary characters
- Asynchronous Loading: Loading resources asynchronously to prevent render-blocking and ensure faster initial page loads
- Caching: Utilising browser and server-side caching to store frequently accessed resources
5. Optimised Media
- Image Compression: Reducing image file sizes without compromising quality
- Proper Image Formats: Using modern image formats like WebP for better compression and quality
- Lazy Loading: Loading images and media only when they are about to enter the viewport
6. Server and Hosting
- Content Delivery Network (CDN): Distributing content across various geographical locations to ensure fast delivery
- Efficient Hosting: Using reliable and high-performance hosting services that can handle traffic spikes and provide fast server response times
- HTTP/2: Utilising the latest HTTP protocols for faster and more efficient communication between the browser and server
7. Security
- HTTPS: Ensuring the website uses HTTPS to encrypt data, which also improves SEO rankings
- Regular Updates: Keeping the website's software, plugins, and themes updated to protect against vulnerabilities
8. User Experience (UX)
- Fast Interaction: Ensuring that users can interact with the website without delays
- Smooth Navigation: Providing intuitive and quick navigation to help users find what they need effortlessly
- Accessibility: Making sure the website is accessible to all users, including those with disabilities
9. Minimal Downtime
- Reliability: Ensuring the website is available and functioning correctly at all times
- Monitoring: Using tools to monitor website uptime and performance, allowing for quick response to any issues
