Optimizing a website using Google PageSpeed involves implementing recommendations to enhance loading speed and web page performance, aiming to achieve a high score in the PageSpeed Insights tool provided by Google. This tool assists web developers and site owners in assessing how quickly pages load for users on various devices and connections, offering suggestions for performance improvement.
Why should you optimize your website?
In search engines, particularly Google, there are algorithms that rank websites in search results. Page loading time is a crucial factor influencing a site's position. The loading time of visible page content, including scripts, images, pop-ups, videos, and other media files, is considered. The goal of optimizing a website using Google PageSpeed is to ensure a user-friendly browsing experience through fast and smooth loading, which can contribute to audience engagement and increased conversion rates.
Methods to accelerate page loading
Optimization for Google PageSpeed includes the following steps:
- Resource minimization: reducing the size of images, styles, scripts, and other files on the page. This may involve image compression, using compressed file formats, and reducing unnecessary code;
- Caching: utilizing browser caching to store static resources, such as images, styles, and scripts, on the user's side. This helps reduce loading time in subsequent visits;
< /body > tag;
- CDN Usage: employing a Content Delivery Network (CDN) to distribute static resources on servers located closer to users, improving loading speed;
Minimization and organization of files on the page
If there are large files on web pages, it is important to compress them. The code of CSS or JS files can have hundreds of lines, which affects the loading speed of the project. To compress voluminous files, you can use the site https://csscompressor.com/ or other similar resources. Analyze all files used on the page. Discard those that are not required or combine them into one. If you can't merge the files, move them to the footer. Moving down a website can be applied to components such as:
- Pop-up windows.
Moving them to the footer will not affect their functionality, but they will not create additional loading while displaying the main content section.
Images and multimedia
Despite images being much lighter than videos, they also require optimization. Similar to CSS files, images can be compressed. Popular resources for image compression include:
However, such actions do not always lead to improved Google Page Speed scores. Therefore, it is recommended to use WEBP images. It's worth noting that this format is not supported by all browsers, so it's advisable to include multiple "source" options under the "picture" tag in your code. For instance, you can use both WEBP and JPEG formats. If the browser can process WEBP, it will appropriately load this format.
No website can do without fonts. However, font libraries contain a vast number of characters, and only 15-20% of them are actually used during operation. So why load a bulky font library that affects page rendering speed if it's not necessary? On the website https://www.fontsquirrel.com you can generate a font by removing unused characters.
By following these simple tips, you'll be able to improve your Google Page Speed scores and reduce the time it takes to display content on your page.
