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.

To understand the effects of non-composited animations on performance, one must first comprehend the browser’s rendering process. The ‘rendering pipeline’ describes the six sequential steps a browser undergoes to display a page. Each stage impacts the ones following it. All stages, except the last one (compositing), are influenced by their predecessors.
As previously stated, every step in the browser’s rendering pipeline has a direct impact on the subsequent steps.
This primarily affects your page performance in two ways:
By steering clear of non-composited animations, you can lessen the workload on the main thread, resulting in an improved user experience.
Composited animations (such as opacity and transform) are carried out on a separate compositor thread and do not instigate pixel repainting. This ensures a smoother loading of your page, eliminating unexpected layout shifts and/or page jank.
In general, try to only perform composited animations, especially, for the animated elements identified by GTmetrix.
