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:
Using an efficient cache policy to serve static assets can enhance page load speed during subsequent visits by saving these files in the user’s browser locally.
With browser caching enabled, the first time a user visits your page may not be faster; however, any future visits will benefit from the cached content, making them faster.
When a browser stores your page’s static resources in its cache, it’s essentially creating a local copy of those resources.
The file’s server dictates how long the browser should hold onto the file – this is what’s known as a caching policy.
A longer caching policy instructs the browser to store these files for an extended period (for instance, a year). This is particularly crucial for resources that aren’t likely to change often, like your page’s fonts or logo image.
Resources with short cache policies are likely to be downloaded from the server again during repeat visits. Caching makes your webpage load quickly for repeat users. Serving static resources from a browser cache significantly boosts your webpage’s speed for returning visitors.
On the other hand, if you set long cache policies for content that changes often, the browser might serve the outdated, cached content to your visitors, even if the actual content has been recently updated.
If your static files don’t change (or if you have a suitable cache-busting strategy), it’s advisable to set your cache policy to 6 months or 1 year.
For finished websites, elements like global CSS/JS files, logos, images, and so on, typically don’t change significantly, making 6 months or 1 year a practical cache expiry to use.
If you frequently modify the above static files, you can choose a shorter cache expiry, provided it’s longer than three months.
To set up an efficient cache policy, follow the instructions below, depending on the web server used to serve your static assets:
1. For Apache servers
Copy and paste the below code into your .htaccess file.
3. For WordPress (or other CMS) Users
If you’re using a CMS (e.g., WordPress), you can use am optimization plugin to cache and set a cache policy for your website.
