Core Web Vitals<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Visit <strong>Core Web Vitals<\/strong> are metrics that Google uses to evaluate the user experience. They consist of three elements:<\/p>\n<ul>\n<li><strong>LCP<\/strong> (Largest Contentful Paint): Measures the loading speed of the main visible element on the page. A good score is under 2.5 seconds.<\/li>\n<li><strong>FID<\/strong> (First Input Delay): Measures how responsive your page is when a user clicks a button or performs an action. Ideally, this should be less than 100 ms.<\/li>\n<li><strong>CLS<\/strong> (Cumulative Layout Shift): Measures the visual stability of the page. It should not exceed 0.1 to ensure a smooth user experience.<\/li>\n<\/ul>\n<p>These three criteria are essential for determining whether your website is well-optimized or if improvements are needed.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Les_recommandations_de_PageSpeed_Insights\"><\/span>2. PageSpeed Insights recommendations<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The report by <strong>PageSpeed Insights<\/strong> also gives you suggestions on how to improve your score. For example, it might suggest that you:<\/p>\n<ul>\n<li><strong>Minify the JavaScript<\/strong> : Reducing the size of JS files can speed up loading.<\/li>\n<li><strong>Optimize images<\/strong> : If your images are too large, it will slow down the loading time. Be sure to compress them and use lighter formats like WebP.<\/li>\n<li><strong>Enable Gzip compression<\/strong> : This compresses the resources sent by your server to reduce their size.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Comment_ameliorer_les_performances_de_votre_site\"><\/span>How can you improve your website's performance?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Now that you understand the importance of speed and have used <strong>PageSpeed Insights<\/strong>, It\u2019s time to take action to improve your website\u2019s performance.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Optimisation_des_images\"><\/span>1. Image optimization<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Images can significantly slow down your website\u2019s loading speed. To prevent this, it\u2019s essential to optimize images before uploading them. You can use tools such as <strong>TinyPNG<\/strong>, which compresses your images without sacrificing their quality. Also, consider using formats such as <strong>WebP<\/strong>, which are much lighter than traditional formats such as JPG or PNG.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Minimiser_et_fusionner_les_fichiers_CSS_et_JavaScript\"><\/span>2. Minify and combine CSS and JavaScript files<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A slow website may be caused by excessive use of CSS and JavaScript files. It is therefore important to <strong>minimize<\/strong> these files (removing whitespace and comments) and, if possible, to <strong>merge<\/strong> to reduce the number of HTTP requests. Tools such as <strong>UglifyJS<\/strong> or <strong>CSSNano<\/strong> allow you to compress these files easily.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Utiliser_un_CDN_Content_Delivery_Network\"><\/span>3. Use a CDN (Content Delivery Network)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If your website receives international traffic, a <strong>CDN<\/strong> can be an excellent way to speed up page loading. By distributing your files across multiple servers around the world, a CDN allows users to access resources that are closer to them, thereby reducing load times.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Ameliorer_la_configuration_du_serveur\"><\/span>4. Improve the server configuration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Another aspect that is often overlooked is server configuration. If your hosting provider doesn\u2019t offer fast response times, this can slow down your entire site. In this case, it may be a good idea to switch to a faster hosting plan or to configure your server to improve its responsiveness.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Pourquoi_suivre_les_recommandations_de_PageSpeed_Insights\"><\/span>Why follow the recommendations of <strong>PageSpeed Insights<\/strong> ?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It is essential to understand that every millisecond counts. <strong>PageSpeed Insights<\/strong> is not just a performance metric, but a guide to a faster, more efficient website.
