Strategies to improve the speed and performance of WordPress sites

Nobody on the internet likes to wait for a website to load. Call it impatience or convenience, but people are not used to seeing a page buffer. And most sites can deliver fast-loading interfaces. Then why should you stay behind?

In this blog, we will discover how to optimize your WordPress core. Let us get to it!

Introduction to Performance Optimization of WP Website

Not having a website that loads swiftly will make your visitors doubt the quality of your online business. Google also determines a website’s rank based on its page performance and other factors. It also advises to build a site with a loading time of two seconds or less.

WordPress, sometimes, throws a curve ball at you when it comes to its website’s performance optimization. While the process is not very complex, it does take a bit of patience to get by. But our guide about levelling up your website’s performance might be able to help here.

Why is Site Speed and Performance in WordPress an Issue?

WordPress does not perform only one function. The CMS pulls data from multiple sources when visitors land on your page. Your database and theme files are combined into HTML and sent to the visitor.

Multiple themes and plugins consume plenty of resources, even when inactive. It’s natural for your pages to slow down when so many things are working together constantly to run it. However, there are some measures you can take to change it without compromising the quality of your WordPress website.

Measuring Website Performance

To improve the performance of your website, we need to know how it is performing at present. Nevertheless, it is also a good idea to engage in continuous performance monitoring.

Many factors on your visitor’s end also determine the website’s performance, like the strength of their internet connection or geographical location. Page speed also varies from one to another, usually depending on the content. For an estimation, you can test your homepage and whichever page gains the highest traffic to determine the speed. Free performance testing tools can also help you monitor it.

For example, paste the tool Website Grader in your homepage URL and observe your site’s performance. It also provides you with some do-able speed suggestions. Feel free to make the changes and test the site as much as you want for reducing server response time.

Pro Tip: If, like Ninegravity, you are also using Wp-engine as your hosting provider, then you can boost your page speed with just one click. Just go to the WP engine user portal and activate the option.

Optimizing Web Hosting

Opting for the right hosting provider can be a game-changer. This is not just for the website’s speed and performance but also because it affects your site’s SEO. You should pick a plan based on your requirements and bandwidth.

For example, shared hosting might not be an ideal fit if you are looking for high-performance metrics. This type of hosting allows you to host several websites on the same server. So, if one website takes a hit regarding page speed and performance, all of them suffer.

Instead, buy dedicated, managed, or VPS hosting plans from a reputable provider.

Optimizing Images in WordPress

Large images don’t do you any good. For optimizing images in WordPress, try these:

• Compressing files without compromising on quality

• Adding alt texts

• Specifying image titles

• Creating an image sitemap

• Using WordPress plugins for image optimization

Some suggestions for these plugins are:

• Smush image compression and optimization

• ShortPixel image optimizer

• TinyPNG — JPEG, PNG & WebP image compression plugin

• EWWW image optimizer

• Kraken.io image optimizer

Using Caching Plugins

As discussed earlier, WordPress pages are built from scratch whenever someone visits your sites. It runs the process, finds the required information, and puts it together to display the finished product to the user.

Since this process can slow your website, a caching plugin can optimize your interface. Instead of generating pages from scratch, it stores a copy of the pages and presents them to future users upon receiving the request.

Some suggestions for caching plugins:

• WP Super Cache

• WP Rocket

• SiteGround Optimizer

• W3 Total Cache

Configuring Browser Caching

By configuring browser caching, you instruct your visitor’s browser to store specific files (such as images, stylesheets, and scripts) locally. As a result, when users revisit your site, their browsers can retrieve these files from their cache. Hence, no new requests are made from the server. Not only does it help in reducing server response time, but it also enhances the user experience.

Minifying CSS and JavaScript

CSS and JavaScript are fundamental to your site’s functionality. Whenever a visitor loads a page, these files are sent from your web server to a web browser. Given the back and forth, your site can slow down and run inefficiently.

To have a seamless experience, focus on minifying CSS and JavaScrip files. Remove unrequired spaces, line breaks, characters, and comments to reduce the file size as much as possible. The less data is transferred, the faster the site’s speed.

WP Engine’s page speed boost option automatically minifies this code. You can also use WordPress plugins like CSS Compressor or WP Rocket.

Reducing HTTP Requests

Many WordPress themes and plugins load different files from other sources besides your own site’s elements. These are called external scripts, which your website uses, but your web server does not store them.
