Firstly, it’s crucial to use the appropriate tools for assessing page speed. We recommend using https://tools.pingdom.com/ or any other reliable alternative for accurate results. It’s worth noting that Google PageSpeed Insights may not provide direct page loading times but rather suggestions for optimization, which might not always translate into significant improvements in speed, especially for smaller websites.
While a high score on PageSpeed Insights can be beneficial, it doesn’t necessarily guarantee fast loading times. For instance, even with a perfect score, your site might still load slowly if loading time issues are not addressed directly.
Upon reviewing hundreds of websites, it mostly appears that caching is either not configured or not properly set up. Caching plays a significant role in improving page loading speeds, especially for mobile devices. To address this, we recommend installing a caching plugin such as Fastest Cache (https://wordpress.org/plugins/wp-fastest-cache/) for free or WP Rocket (https://wp-rocket.me/) for premium features.
Implementing one of these plugins and configuring it correctly should help optimize your website’s loading times across all devices, including mobile.
