How to speed up WordPress surely is a hot topic these days. Fortunately, there are numerous techniques that you can employ to get the job done. So, our intent here is to list every trick we know of that can make your WordPress site a lot faster.
1. Choose a better web hosting provider
The major factor that influences the speed of a website is the hosting of your WordPress website. It might seem like a good idea to host your new website on a shared hosting provider that offers “unlimited” bandwidth, space, emails, domains and more. However, the point that we usually miss out on regarding this offer is that shared hosting environments fail to deliver good loading times on peak traffic hours, and most fail to provide 99 percent uptime in any given month.
Shared hosting tends to deliver a poorer performance because you are sharing the same server space with countless other websites, and there is no telling how much resources others are using. Plus, you don’t know exactly how well the servers are optimized.
Thankfully, the web-hosting industry has advanced with technology, and the prices of cloud hosting providers have decreased with the passage of time. In the present times, you can buy dedicated cloud servers from SiteGround, DigitalOcean, Amazon Web Services, and even Google Compute Engine at a nominal price. However, setting those servers up can be a daunting task as you are required to set servers up from scratch. There are web hosting providers like Cloudways (where I work) who make the task of setting up optimized cloud servers as easy as click and launch.
2. Use a lightweight WordPress theme / framework
WordPress themes with a lot of dynamic elements, sliders, widgets, social icons and many more shiny elements are immensely appealing to the eye. But remember this: if they have too many elements and higher page sizes, then they will definitely cause your web server to take a thumping.
The best option here is to use lightweight themes. One solution is to go for one of the default WordPress themes. Another is to try out something like Neve, built by the same guys behind CodeinWP.
3. Reduce image sizes
Images are the major contributors to size increment of a given webpage. The trick is to reduce the size of the images without compromising on the quality.
If you manually optimize the images using Chrome PageSpeed Insights extension or Photoshop or any other tools, the process will take a long time. Fortunately, there are plugins available for just about everything you can think of, including image optimization. The ones worth mentioning are:
Using any of the above mentioned plugins on your WordPress site will drastically reduce image sizes, thus improving the speed of your website.
4. Minify JS and CSS files
If you run your website through Google PageSpeed Insights tool, you will probably be notified about minimizing the size of your CSS and JS files. What this means is that by reducing the number of CSS and JS calls and the size of those files, you can improve the site-loading speed.
Also, if you know your way around WordPress themes, you can study the guides provided by Google and do some manual fixing. If not, then there are plugins that will help you achieve this goal; the most popular being the Autoptimize that can help in optimizing CSS, JS and even HTML of your WordPress website.
5. Use advanced caching mechanisms with a caching plugin
WordPress caching plugins (e.g. W3 Total Cache) have been there for a long time, making the complex tasks of adding caching rules to your website elements easier. Combining such plug-ins with advanced caching mechanisms like Varnish could help you better the loading speed of your website and ultimately speed up WordPress considerably.
