Why Should your WordPress Load Fast?

For a long time now, load time has been a core ranking factor that Google and other search engines take seriously.

In fact, Search engines such as Google prioritize delivering relevant information to users as quickly as possible, making slow-loading sites suffer great loss – poor search ranking.

The earlier research that shows 53% of mobile users bounce off sites that load for more than 3 seconds also acknowledged that the average mobile site takes 15 seconds to load. 

This is a problem that needs to be resolved. A slow-loading site is bad for both search engines and web users.

To sum it up, A fast-loading site will:

  • Improve user experience
  • Reduce bounce rate
  • Increase dwell time
  • Increase conversion and also improve the overall site’s SEO (better search rankings).

How to Test WordPress Site Speed

There are different ways to run a WordPress speed test. You can simply load the site on a browser and take note of how long it takes to load.

But a better and recommended approach is to leverage any speed testing tool. Most tools will only require you to enter your domain name, and that’s all.

Even though some of the speed testing tools are not always accurate, they can give a better hint of how slow or fast your site loads.

For example, GTMetrix is a speed testing tool that will not only show your site’s load time, it will also outline suggestions you can use to improve the speed.

Here’s what a speed test looks like on Gtmetrix:

There’s nothing to optimize on Technumero. It’s an excellent result (100%).

Besides GTmetrix, here are other site speed tools:

There are several types of plugins that can help your site load fast. We have caching plugins, image optimization plugins, file optimization plugins, etc.

Based on the results of your speed test, you’ll be able to capitalize on what type of plugin would resolve your site speed.

For instance, if GTmetrix recommends serving scaled images, image optimization plugins will come in handy. If the suggestion is to leverage browser caching, caching plugins will come in handy.

Without further ado, let’s dive into the list.

Best Caching Plugins

Caching plugins are the most popular option for speeding up your site. The longer the cache lifetime, the faster your site will load.

The cache allows browsers to store some elements of your site when a user visits it and then renders it again when the user revisits. 

Below ar some of the best WordPress caching plugins.

Smush (WP Smush.It) - WordPress Image Optimization Plugin

Interestingly, CDN Enabler is another robust plugin that helps you set up a content delivery network to accelerate your site’s speed.

Unfortunately, this plugin doesn’t work with Cloudflare. It’s specifically for KeyCDN, StackPath, and other CDNs that provide a CDN URL.

To use this plugin, you need to sign up for a CDN (KeyCDN, StackPath, or any other CDNs that provide a CDN URL), then enter your CDN URL into the CDN Enabler plugin. 

That’s it!.

Features:

  • 1-click to clear cache

Google fonts usually cause a delay in load time when served from fonts.gstatic.com. To solve this, you need to host fonts locally to prevent third-party requests.

This is where OMGF comes in. It can solve font-related errors by downloading all your Google Fonts (using the Google Fonts Helper API) and generating a stylesheet for them, then rewrite every URL (pointing to fonts.gstatic.com or fonts.googleapis.com) to the locally hosted variant.

Price: 

OMGF has a free and a pro plan. The Pro plan provides a better performance and works perfectly with your theme. 

It costs €29.00 for one site, €59 for three websites, €89 for five sites, and €119 for unlimited websites.

This is a common font issue that causes slow load time.

To fix this, you can use the Swap Google Fonts Display plugin. It allows browsers to use the fallback font then swap fonts when the download of the actual font is complete.

For sites with small-mid traffic, this service is not needed for offloading media. Cloudflare or BunnyCDN is fine.

Features:

It offloads media to DigitalOcean Spaces, Amazon S3, or Google Cloud Storage and integrates with Cloudfront.

Price: 

WP Offload Media offers both free and pro plans. The Pro plan is loaded with more features like WooCommerce integration, Assets pull addon, email support, etc.

#40. Heartbeat Control by WP Rocket

If you care about effortlessly managing the frequency of your WordPress heartbeat API, Heartbeat Control by WP Rocket is your best bet.

WordPress Heartbeat API gives real-time communication between a browser and the server when you logged into WordPress.

This feature is cool. But if you usually open your WordPress admin for longer periods, like, when writing or editing posts, the AJAX requests from the API can pile up and generate high CPU usage which leads to poor server performance.

With Heartbeat Control by WP Rocket, You have full control over the WordPress Heartbeat API. You can decide to limit or completely stop its activity.

#41. AMP For WP

Accelerated Mobile Pages (AMP) is used to make websites faster for mobile visitors. When AMP is added to a webpage, the page should load in less than a sec.

I don’t usually recommend AMP because it can disfigure your site’s design. Also, research by Kinsta shows AMP can sometimes decrease mobile conversions.

But if you must use AMP, AMP For WP is your best bet. It has a lot of customization options that when done right, will give a perfect result.

Price:

Aside from the free plan, AMP for WP has a membership program that gives you access to many more plugins and features other than AMP for WP. This starts at $149 per year for 1 site.

#42. Widget Disable
