Don’t be overwhelmed by the table below; most optimizations can be easily achieved with an optimization plugin. I personally use the free Speed Optimization plugin that comes bundled with SiteGround’s Hosting plan. However, there are several other options, including W3 Total Cache (W3TC), WP Rocket, and FlyingPress.
2. Review the Report: GTmetrix will quickly generate a performance report, pinpointing each area that requires improvement.
3. Consult our table below to address the specific areas highlighted by GTmetrix. While GTmetrix often uses complex terminology, overcomplicates its instructions, and provides guidance for a broad spectrum of websites, we’ve streamlined and tailored their recommendations specifically for WordPress sites. With our clear and straightforward guidelines, you’ll find it much easier to understand and implement the necessary changes.
4. Re-test After Implementing Changes: After making a change, clear your website’s cache if it’s enabled. Re-test on GTmetrix to assess the impact of your adjustments. Using the new results, move on to the next suggested improvement and continue the process.

Implementing this feature can be achieved by using an Optimization Plugin:
When any of these tasks take more than 50 ms to run, referred to as a “long task”, they can prolong both the First Contentful Paint and the duration it takes for your page to be fully interactive.
To provide an optimal page experience for your visitors, it is critical to minimize long main-thread tasks as much as possible. How does your site score on this audit?
Each time your page loads, the browser employs the main thread to manage the majority of tasks associated with displaying your page content and handling user interaction.
By reducing the quantity of these long main-thread tasks, you can boost your page’s overall performance by decreasing the workload on the main thread.
Consequently, visitors may witness faster content display on your page and engage with it more quickly.
Reducing the workload on the main thread should be a primary objective in your development process. You can largely achieve this by:
Several strategies can be implemented to accomplish these goals, which include:
Evaluate the third-party code on your website and eliminate those that do not contribute any substantial benefits. Enhance other scripts by delaying those that aren’t crucial, setting up early connections to vital third-party domains, enabling lazy-loading for embedded third-party content, and fine-tuning third-party hosting.
Steer clear of using input handlers that run for extended periods (which might obstruct scrolling) and refrain from modifying styles within input handlers (which could potentially lead to pixel repainting). Implementing a debounce technique for your input handlers effectively addresses these issues.

Reduce the time spent parsing CSS by minifying, or deferring non-critical CSS, or removing unused CSS.
Adhere to using compositor properties to keep events off the main thread. These properties run on a distinct compositor thread, thus liberating the main thread for more extended periods and enhancing your page loading performance.
