1. Reduce server response time
Do you get 'reduce server response time' warning on Google PageSpeed Insights? Now we can make a close look at the probable reasons for your high server response time and ways to boost your website speed.
Server response time (Time To First Byte) is the time taken by the browser to receive first byte from the server. It should be under 200 ms. If it takes more time to load the first byte, your website will become damn slow.
A server response time depends on several factors, like:
A. Bad hosting
If your hosting provider uses outdated servers and old technologies, it will slow down your website and sent it to offline frequently. Ensure that your website runs on the latest PHP version to make it fast and secure. Otherwise, consider change your host.

2. Leverage browser caching
Leverage browser caching is another warning you may get in website speed test tools like GTMetrix. Let me explain why it occurs on your site, first. Then, I will guide you with the multiple methods to remove warning and speed up WordPress.
Browser caching is a mechanism to store frequently accessed your web resources in the user browser. When a visitor enters your website for the first time, it may take some time load pages depends on the size of your files. But for their repeated visits, your page will open quickly as required resources are stored in the local memory of their device.
If you are getting leverage browser caching warning on GTMetrix, here is an easy way to remove the message for files hosted in your server: Install WP Rocket
WP Rocket will enable browser caching for desktop and mobile, and fix the warning automatically. It will set an expiry period for different types of files and update your .htaccess file accordingly (otherwise, you should do it manually). But keep in mind that browser caching cannot be applied for files stored in external servers like Google, Facebook, ad scripts, etc. Any WordPress plugin is helpless in this case. Even though, WP Rocket can handle Google Analytics and Facebook Pixel scripts. So you won't get leverage browser caching warning for them.
If you are not using any caching plugins and want to set an expiry time for files manually, follow these steps.
Open your .htaccess file from the root directory. Click on edit and enter this code for Apache servers,
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/webp "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresByType video/mp4 "access plus 1 year"
ExpiresByType video/mpeg "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
Save the file.
WP Rocket users can visit Add-ons from the left-side menu and activate Google Tracking, Facebook Pixel add-ons to turn on browser caching for them.

3. Eliminate Render-Blocking Resources
There are two types of resources- critical and non-critical resources. You can defer non-critical resources with async or defer attributes. But you can't handle critical resources in the same way as it may break down your website. So you should inline them within the HTML page using <script> and <style> tags.
Solution: Install WP Rocket
Install WP Rocket on your WordPress website first. Open settings > WP Rocket and visit File Optimization tab.
Open SG Optimizer menu from the left pane of your WordPress dashboard. Visit the Frontend optimization tab. Locate 'Defer Render-Blocking JS' option and drag its toggle button to the right to enable.
You can also consider: W3 Total Cache
Install W3 Total Cache on your website and open Performance > General settings. Locate Minify settings.
Enable the Minify option first. Change minify mode to manual. Save settings.
Go to GTMetrix or Google PageSpeed Insights and collect scripts that you want to minify with GTMetrix.
Copy file URLs one by one and go back to WordPress dashboard. Visit Performance > Minify section.
Scroll down to JS minify settings. Find the first option ' Before </head>..........' and Choose Non-blocking using defer from the embed type drop down box. Under JS file management, click on Add a script button and enter scripts you copied from the speed test tools. Save settings.
For CSS files, head to the next section- CSS.
Click on 'Add a style sheet' button and enter CSS file URLs one after another to minify. Save settings and purge caches.
Visit Google PageSpeed Insights and test your website again. It should remove the warning relating to eliminate render blocking resources.
4. Enable GZIP compression
Are you getting GZIP related warnings on website speed test tools? It will be 'Enable GZIP compression' on GTMetrix and 'Compress components with gzip' on Pingdom. You can easily fix the warning either by updating your .htaccess file or installing WP Rocket. Let us check how it works.
For Apache servers, you need to add the following code in the .htaccess file to enable compression.
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject

BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
Header append Vary User-Agent
