Why Performance Matters
Performance directly correlates to user satisfaction, conversion rates, and search engine rankings. Google’s search algorithm considers web performance metrics, which means a slow site may be buried in search results. Plus, fast-loading sites keep users engaged, leading to lower bounce rates and higher conversion rates.
Performance Optimization Essentials
Dialing up your digital performance can feel overwhelming. With dozens of tips and techniques out there, where should you focus first? Here’s a comprehensive, actionable list of 50 essentials to get you on the fast track to an optimized site.
-
Leverage Browser Caching: By instructing the browser to keep certain files for a pre-determined time, you can reduce server load and speed up page load times for repeat visitors.
-
Enable Compression: GZIP compression reduces the size of your CSS, HTML, and JavaScript files, as well as images, sending them over the network faster.
-
Prioritize Critical Above-The-Fold Content: Load essential content first to ensure users receive relevant information without excessive delays.
-
Minify CSS, HTML, and JavaScript: Remove unnecessary characters, such as whitespace and comments, to reduce file size and improve load times.
-
Reduce Server Response Times: Optimize your server-side speed by upgrading hardware, utilizing caching, or streamlining your database queries.
-
Minimize Redirects: Each redirect adds a round trip time to the HTTP request/response cycle, which can negatively impact your page speed.
-
Remove Render-Blocking JavaScript: Only load critical scripts initially, deferring non-critical scripts that can load later.
-
Optimize Images: Properly format and compress your images without losing quality to significantly reduce page load times.
-
Use a Content Delivery Network (CDN): A CDN delivers your content through servers closer to the user, speeding up delivery and reducing load on your primary server.
-
Keep JavaScript and CSS External: This technique can improve caching, allow for faster rendering, and make it easier for search engines to index your website.
-
Choose the Right Hosting: Ensure your web host is fast and reliable, with features like SSD storage, the latest PHP version, and efficient server setups.
-
Monitor Your Performance Regularly: Assessing performance allows you to identify slow pages and their causes, aiding in targeted improvements.
-
Lazy Loading: Load images and videos only as they’re about to become visible on the user’s screen, rather than all at once.
-
Use Efficient Coding Practices: This includes avoiding inline CSS and JavaScript, and combining files to reduce the number of requests.
-
Implement Expires Headers: Specify how long web browsers cache the resources your website serves to them.
-
Remove Unused Code: Periodically check for and delete any code or plugins that aren’t actively used on your website.
-
Reduce the Number of Plugins: Each installed plugin can slow your site. Only use plugins that are necessary and from reputable providers.
-
Enable HTTP/2: The updated, faster version of HTTP can significantly improve site speed, especially for users with a high latency connection.
-
Optimize Your Database: Ensure it’s clean, efficient, and indexes are configured properly to speed up queries and site performance.
-
Pick the Right Image Format: Use JPEGs for photographs, PNGs for images with text, and GIFs for simple images.
-
Preconnect Resources: Specifying a resource to be used by the current page or its navigation can reduce the waiting time for users.
-
Serve Scaled Images: Resize images to the exact dimensions required, ensuring they load as fast as possible without wasting bandwidth.
-
Enable Keep-Alive: This feature allows the same TCP connection to handle multiple requests, eliminating the need to create a new connection for each resource.
-
AMP (Accelerated Mobile Pages): For mobile users, AMP can dramatically increase page speed and improve user experience.
-
Prefetching: Predict what users are likely to do based on their current actions and have resources ready to load instantly.
-
Host Videos Externally: Instead of self-hosting videos, use a platform like YouTube, which is optimized for video delivery.
-
Use Asynchronous Loading for CSS and JavaScript: Help incrementally render your site, making it appear faster to users.
-
Combine Background Images: Merge small images into a single image about two to three times per second to help avoid adding extra requests.
-
Switch to a Faster DNS Provider: A faster DNS will translate your domain name into an IP address more quickly, reducing lookup times.
-
Enable and Configure Browser Cache: In addition to leveraging cache, ensure it’s correctly configured to save frequently accessed resources.
-
Use Sub-Domain for Static Content: Serving static content from a sub-domain has caching benefits and reduces the size of cookies that are sent.
-
Use Cache-Control Headers: Together with Expires headers, these control how long your resources are cached and help with performance.
-
Avoid CSS @import: Use an external stylesheet link instead to prevent delaying the rendering of the page.
-
Disable Hotlinking: Prevent others from linking directly to your resources, which can slow down your page load times due to their bandwidth usage.
-
Enable and Configure SSL: SSL isn’t just for security—it can also speed up your website thanks to HTTP/2 being available securely by default.
-
Defer Parsing of JavaScript: Limit parsing (and therefore, execution time) to resources not critical for rendering above-the-fold content.
-
Strict and Non-Blocking Scripts: Use “async” and “defer” attributes for scripts that allow them to load without stopping parsing of your page.
-
Compress Text-Based Files: Not just HTML, but CSS, and JavaScript, too, should be compressed for faster delivery.
-
Inline Critical CSS: By serving the most vital subset of your site’s CSS inline, you can remove render-blocking delays.
-
Monitor Third-Party Services: Ensure every third-party tool or resource is optimized, or consider if you can live without it.
-
Fine-Tune Your Web Server: Adjusting settings like Keep-Alive timeout, DNS lookups, and many other server-related factors can improve performance significantly.
-
Implement a Scalable Architecture: Design your website’s infrastructure to scale, so it can handle traffic spikes without sacrificing speed.
-
Regularly Update Your Software: From CMS to plugins, outdated software can harbor performance issues and security vulnerabilities.
-
Set a Correct Cache Expiry: Always remember to set how long you want to cache static data, not too long (potential for outdated content) and not too short (missed performance opportunity).
-
Speed up TTFB: Time To First Byte should be minimized. Start at the server and optimize all the way to the front end.
-
Use Browser Hints and Preloaders: Mozilla’s X-DNS-Prefetch-Control and Chrome’s rel=preload are good beginnings for giving loading instructions to the browser.
-
Monitor Critical Success KPIs: Beyond speed, monitor what brings success to your pages – be it sign-ups, clicks, or purchases – to ensure performance aligns with business objectives.
-
Optimize for Modern Browsers: Keep your focus on optimizing for the most used browsers and versions to avoid spending your efforts on legacy issues.
-
Utilize Efficient Anti-Malware Solutions: Security comes with performance costs. Choose solutions that offer strong protection with minimal impact on speed.
-
Embrace Mobile-First Design: A design that considers mobile usage as primary ensures that performance is considered from the ground up.
