In the ever-evolving digital landscape, optimizing your website’s page speed is crucial, especially since Google considers Core Vitals metrics as a leading ranking factor. These metrics prioritize websites that offer the fastest and best mobile experience. Here’s how to craft a lean, swift website that stands out.

The essence of speed optimization lies in asset management. Begin by ensuring your images are the exact size they appear on screen. Avoid resizing a 1000px wide image to 300px in CSS—this wastes space. Compressing your images can reduce their size by up to 80%. We rely on Compressor.io for lossless compression, which has served us well for years.

For background images, avoid loading large 2300px wide photos on a 400px phone screen. Instead, resize to 500px for mobile, drastically reducing load times from 2.3MB to as low as 37k. Use larger images for tablets and desktops by resetting the background image size accordingly. This practice ensures faster loading times across devices.

Implement the “srcset” attribute to serve the right-sized images for different screen sizes. By providing a list of image sizes and using “src” as a fallback, you ensure efficient loading. Additionally, specify the height and width attributes to minimize content layout shifts, improving both speed and stability.

Employ lazy loading using the loading=”lazy” attribute supported by most browsers. This defers the loading of images not immediately visible on the screen, enhancing speed. However, avoid lazy loading images that are above the fold to prevent content layout shifts.

JQuery, once a staple, is now largely redundant. Modern JavaScript can handle most of its functions, making JQuery unnecessary and potentially slowing down your site. Removing it can enhance security and speed. Google Fonts CDN links should also be replaced by locally hosted fonts. Use @font-face to load fonts, eliminating render-blocking resources and speeding up load times.

Here’s a sample code snippet for your CSS:

Add the defer attribute to your script tags to postpone JavaScript loading until after the HTML and CSS have fully loaded. This ensures a smooth and uninterrupted page render.

Where possible, use SVGs over PNGs. SVGs are lightweight and load faster. Websites like Flaticon (https://www.flaticon.com/) offer customizable SVG graphics and icons. Converting logos to SVG format is also beneficial, as it improves scalability and optimization.

Finally, use Google Lighthouse in your developer tools to assess your website’s performance. Address accessibility issues and strive for a 96+ page speed score and high Lighthouse ratings to ensure your site is polished and optimized.

By following these steps, you can sculpt a website that not only meets Google’s stringent Core Vitals metrics but also provides a superior user experience. Happy optimizing!
