It is worth remembering, however, that the PageSpeed Insights indicator does not reflect the speed of the website and is not a reliable test of the website's performance. It only indicates the current level and potential of website optimization in the areas that the tool pays attention to.
Also note that the high level of complexity of the target page makes it difficult, and sometimes even impossible, to achieve the highest results in PageSpeed. If you have impressive animations, many media, numerous Java Script libraries on your page, the result may be average, and its optimization without giving up some of the functionality of the page will be very difficult. Remember that this tool is very good for planning the optimization of the website, but we should not treat it as a reliable measurement of the performance of the website .
How to get a high score in Google PageSpeed Insights?
Below you will read about the two main problems we encountered while optimizing our website.
Minify source code and eliminate render-blocking resources
Lack of code minification and render-blocking resources are the two most common problems that contribute to poor Google PageSpeed Insights results. To deal with this, at the final stage of work on a overseas chinese in worldwide data website, when the entire source code is ready, we merge all CSS style files and JavaScript libraries into a single CSS and JS file, and then reduce the entire code to a single line. Such an optimized file is not readable by the programmer, but it does not matter to the web browser (it will read it just as well). Thanks to this solution, the web browser sends fewer requests to the server, and the requested files are smaller. In an effective way, the time of opening the website will be shortened.
Recommended tools:
Combine JS files – minifies and merges JS files in a fixed order
WinLess – compiles LESS files (CSS preprocessor) and returns minified CSS file
Display images in next-generation formats
When creating a website based on the WordPress CMS, you will solve this issue in a few clicks. All you need to do is install and configure the Images to WebP extension . The extension allows you not only to optimize files in the media library, but also to customize images that are an integral part of your website template.
Pay attention to the above tips when implementing your own website, and your site's Google PageSpeed score will surely be above average.
