A fast WordPress site is critical for user experience, SEO, and overall site performance. Over time, outdated methods for speeding up your WordPress blog can slow your site down, so here’s a revamped guide to improving your WordPress performance in 2024.

1. Run Performance Tests First

Before diving into optimizations, you need a clear picture of your site’s performance. Use tools like Google PageSpeed Insights or GTMetrix to evaluate speed and identify specific bottlenecks. These tools not only provide load times but also actionable recommendations. Regular testing is key, especially after installing new plugins or making significant changes.

2. Upgrade Hosting for Speed

Your hosting provider plays a massive role in performance. Shared hosting may be cheap, but as your site grows, it can cause slowdowns, especially during traffic surges. Consider moving to managed WordPress hosting or cloud hosting for better resource allocation and scaling options. Popular providers like WP Engine and Cloudways offer optimized environments designed to boost WordPress performance by handling caching, backups, and security seamlessly.

3. Optimize Images Efficiently

Large image files can dramatically affect load times. Use tools like ShortPixel or Smush to compress images without sacrificing quality. You can also enable lazy loading, which delays loading images until users scroll to them. This improves the initial load time of your pages. Remember to also serve images in modern formats like WebP, which are smaller and optimized for the web.

4. Minimize JavaScript and CSS

External scripts, such as third-party plugins, fonts, or analytics, can slow down your site. Combine and minify JavaScript, CSS, and HTML files to reduce their size and load time. Tools like WP Rocket or NitroPack offer easy-to-use plugins that handle this for you. Moving non-essential JavaScript to the footer can also prevent it from blocking the initial rendering of your pages.

5. Limit Plugins and Use Only What You Need

Too many plugins, or poorly coded ones, can seriously hinder your site’s performance. Regularly audit your plugins and deactivate or delete ones that are no longer necessary. Aim for high-quality plugins that are optimized for performance, and always update them regularly. Reducing unnecessary plugins can also help lower the number of SQL queries and PHP calls to your server, which will boost site speed.

6. Enable Caching

Caching is one of the easiest and most effective ways to speed up your site. A caching plugin like WP Rocket or W3 Total Cache creates static versions of your pages, reducing the load on your server. Some managed hosting providers offer built-in caching solutions, but if you’re not on one, these plugins can be crucial. Caching can make your site up to five times faster by eliminating the need to regenerate pages for each visitor.

7. Use a Content Delivery Network (CDN)

A CDN distributes your site’s content across multiple servers worldwide, delivering it to visitors from the closest location. This can dramatically reduce load times, especially for global visitors. Cloudflare and KeyCDN are popular choices that integrate easily with WordPress, and they also provide added layers of security by mitigating DDoS attacks.

8. Optimize Your Database

Over time, your WordPress database can become bloated with post revisions, drafts, and spam comments. Plugins like WP-Optimize clean up unnecessary data and optimize your database for speed. Additionally, limiting the number of post revisions stored in the database can prevent bloat and maintain quick response times.

9. Upgrade to the Latest PHP Version

Running the latest PHP version ensures your WordPress site operates efficiently. PHP 8.0 or higher offers significant performance improvements, and many hosts allow you to upgrade via the control panel. If your site isn’t using the latest PHP version, you’re missing out on better speed and security.

10. Reduce Redirects

Excessive redirects can slow down your site by creating additional HTTP requests. Audit your site for unnecessary redirects and aim to update outdated URLs directly to reduce redirect chains. Redirect plugins like Redirection help you manage and minimize redirects effectively.

By following these updated techniques, your WordPress site will perform better, offering a smoother experience for your visitors and giving you a leg up on search engine rankings.

Thanks for the comment @blaineblogger … I think anything that takes longer than a few seconds could potentially lose someones interest. I would say under 5 seconds is safe, under 3 seconds is safer 🙂

Hi John, thanks for the great guidance. I have also posted another tutorial about server side javascript and css files compression to speed up WordPress. It has extreme effects on page load times (up to 8 times faster). Some of your readers or even you might interested in and apply it to Rock with your blog 🙂

Hi Jon, maybe I’m a bit late with this comment but I wanted to ask you, since you are using Thesis and recommending WP Super Cache. Is there something in particular you need to do when activating the plugin on Thesis? I see an alert to change the permissions on wp-content because it is writable but I’m not sure…

Thanks for the help man.

Sometimes you need to change the write settings of the wp-content folder so it can save the cached files.

“There are two ways that you can fix this problem. The first option is to chmod using a command. This is what the plugin suggests that you do. If you have SSH access to your server, ssh in and run the command: chmod 777 WP_DIRECTORY/wp-content where WP_DIRECTORY is the directory that your WordPress blog is installed in. You can also find the exact command that you need to run on that WP Super Cache error page that you see.

You will see something similar to this when chmoding with FTP. Make sure that all boxes are checked.

The other option is to chmod using an FTP client. This is probably easier for anyone that hasn’t used terminal before. Connect to your FTP server and find your /wp-content/ folder. It’s in the folder where you installed your blog. Now you have to find the option to chmod. In most FTP programs, you have to right click on the folder and then select Chmod. It really depends on your FTP program. On the chmod box that pops up, make sure that it is either set to 777 or that all of the boxes are checked. If there are any special boxes, like there are on the right, just leave those empty.” – From http://gulati.info/2009/01/using-wp-super-cache/

Wow, great post.
i really didn’t know we could increase the speed of our wp blog, I thought we were stuck with the speed that wp and our host gave us.
I am going to try some of these techniques.

Thanks, Ron

Another thing one can do to speed up their WordPress blog is to choose a hosting plan, which includes solid state drives, or in short SSDs. Since I moved to BGOcloud I’ve noticed that my website speed improved vastly and it is thanks to the SSDs. So, it’s always better to choose them over traditional hard drives, as SSDs will provide you with the fast speed that your website or blog needs.
