Solution that can make WordPress Websites Faster

Leverage Browser Caching:

Browser Caching means “Some of the files are stored / cached in the user’s browser, so that the next time they visit the website, it is directly served from the browser rather than downloading it from the server. The nature of these files being static. ”

Let’s dive a little deeper, In rendering a webpage, all of the files such as HTML, CSS, JS and images are downloaded from the server and displayed to the user. In most of the websites, some of the files/pages are static which means, it does not change frequently such as about us, Contact Us, logo etc.

Caching these files can be greatly beneficial because it ultimately reduces number of requests made which can drastically lower the website load time.
Some of the Plugins recommended are: WP Performance Score Booster, W3 Total Cache, WP Rocket

Add Expire Headers:

Setting Expire Headers to all of the required files greatly reduces the number of HTTP requests and there by the Improving the speed of the website.

Expired headers tell the browsers to serve the cached version of the files rather than downloading it from the server. Therefore always make a point of setting a far/late expiry for all of the static contents such as about us, contact us, or any other element that doesn’t change with time.

Utilize Lazy Loading for Images and Videos:

If your site contains lot of Images/videos then this might be one of the most important points to consider, because these sites take ton of time to load which can affect the overall User Experience.

To Solve this problem, you can utilize lazy loading for all of the Images and Videos used, in which its loading is delayed which means the Images and videos are loaded once the user comes in the viewport area.

Recommended Plugins: a3 Lazy load.

Defer Parsing of JavaScript:

Unless your website contains elements that require some of the JavaScript files (the main being JQuery) to function; follow the practice of loading the JS files at the end i.e.  the footer. It is to be kept in mind that doing this might break site and therefore are it is recommended to check the website (with the cache cleared) , and the console.

One of the Plugin that I really find handy is Autoptimize, because of its simple configuration and if your site is broken it will show you the JS files causing it, which can then be excluded from the deferring.
This step greatly reduces the load on the website, as the parsing is not done at the beginning.


It is always recommended to remove unused plugins and keep only those plugins that are necessary, because having too many plugins not only makes your website hefty but also has a great effect on Speed Optimization since it calls additional files thereby increasing the number of HTTP requests, finally leading to an Increasing load time.


It’s very important that you choose a theme that is well coded, SEO friendly with Responsive design layout that does not come with preloaded flashy elements because these are the pinpoints that affects the performance of your site.

To avoid any confusion, always read the Reviews and the Ratings before getting any of the WordPress themes.

Lossless Image Compression:

If your website has lot of Images, then you need to take this seriously since it  is one of the factor main factor causing the downtime of your website because more the number of Images with large size–> more is the size of the website which increases the page load time. Therefore always follow the practice of optimizing the Images without compromising its Quality.

Some of Recommended Plugins and tools are: Compressor.io and EWWW Image Optimizer.

Following all the above steps correctly will definitely improve the speed of your website, however if you still want to boost the Speed further you can use a CDN.
