A slow-loading website or webpage is not a pleasurable experience for your visitors. Well, not for anyone. Over 3 seconds of load time, most visitors lose patience and leave. Which means you may lose customers, sales, and revenue — which is also lousy businesses.

Nor do search engines like Google like slow loading websites. It may also be a negative ranking factor.  We don’t want that, right.

Nowadays, everything has to go fast. With the vastly growing number of mobile users, (with no patience, me including), your website must load quickly if you want to capture or retain the visitor’s interest.

Are there solutions to help improve the loading time of a WordPress website?

Yes, there is.

Solutions You Should Consider to Speed up a WordPress Website

There are several different solutions to consider to speed up a website. Some valuable and sometimes necessary solutions you should be using to boost the performance are:

Web Hosting

Your web hosting should be reliable and fast. The speed also depends on whether you use shared hosting (usually more slow) where multiple websites utilize a single server.

Alternatively, use a dedicated hosting service (an entire server at your service), which can significantly increase the speed of your website.

Some of the best WordPress hosting to choose from are Kinsta, SiteGround, and Flywheel.


Stands for Content Delivery Network. Meaning, your content can be delivered from different geographical locations/servers to distribute content faster to visitors. If you decide to use a CDN service, your website can significantly improve the load time.

Some of the best CDN providers to choose from are StackPath, Cloudflare, and KeyCDN.

WordPress Cache Plugins

This is yet another solution to improve the performance of your website. With a cache plugin, you generate static HTML files to optimize the speed instead of loading heavy PHP pages and scripts.

Some of the best WordPress Cache Plugins to choose from are WP Rocket, WP Super Cache, and W3 Total Cache.

Lazy Loading Plugins

Are other types of plugins that can help you further speed up your site. With Lazy Loading plugins, you can significantly reduce HTTP requests and only display images when they are visible to the visitor. The images load asynchronously, and if the visitor does not scroll, the remaining images do not load.
