Have you noticed that your website is slow? Well, you’re likely not using a caching solution.
Caching plays a key role in your website’s performance. Without an appropriate caching strategy, your pages will take longer to load, leading to frustrated users and a high bounce rate. Luckily, it’s easy to implement it on your site.
In this post, we’ll explain what caching is and why it’s beneficial. We’ll then explore some caching strategies to supercharge your website’s speed. Let’s dive in!
What Is Caching?
Caching is the process of storing copies of your website’s data, typically on the visitor’s browser or your server.
When a repeat visitor comes to your site, the content is loaded from the cache. This minimizes the strain on your server as it won’t have to fetch and serve the requested data from scratch.
When implementing caching strategies, it’s important to understand two key concepts: cache hit and cache miss.
A cache hit occurs when a user’s browser or a server successfully retrieves requested data from the cache. For example, if a visitor accesses your website and the cached version of an image is already available, their browser will load it instantly from the local storage instead of downloading it from your web server.
On the other hand, a cache miss happens when the requested data is not found in the cache. This usually occurs if the data has expired, hasn’t been cached yet, or the cache has been cleared.
In such cases, the browser or server must fetch the data from the original source, like the web server or database. While this may cause a slight delay in page loading, caching mechanisms ensure that subsequent requests for the same resource result in a cache hit.
Why Is Caching Beneficial?
Let’s take a closer look at the benefits of implementing caching strategies:
- Faster load times. Cached content is delivered to users much faster than dynamic data. This leads to a better user experience.
- Reduced server load. By serving pre-generated data, caching lightens the load on your server. This enables it to handle more simultaneous visitors, so your site’s performance won’t suffer during peak traffic times.
- Improved SEO. Fast loading times encourage users to spend longer on your page, leading to higher engagement rates. This signals to search engines that your site is user-friendly and offers valuable content, which will in turn improve your rankings.
- Lower bandwidth usage. Cached content reduces the amount of data that needs to be fetched from your server, which will save bandwidth costs.
It’s important to mention that there are other things you can do to boost your site’s speed. These include using a lightweight theme, compressing images, and minimizing the number of plugins on your website.
However, caching is one of the most effective ways to improve your site’s performance, especially if you have a large volume of content. You’ll want to cache frequently accessed data like posts and pages.
4 Caching Strategies to Speed Up Your Website
Implementing caching strategies is not as difficult as you might think. There are tools that will serve cached data for you, and many hosting providers also provide database caching for you.
Here are the main caching strategies to consider for your website.
1. Use a Caching Plugin
If you have a WordPress website, you’ll want to install a caching plugin. Many of these tools will have pre-configured settings, so little input is required from your end.
For example, WP Rocket is a powerful plugin that offers a quick setup:
It provides page and browser caching, as well as other features that can enhance your site’s performance. These include lazy loading, GZIP compression, and code minification.
If you’re looking for a free caching plugin, there’s W3 Total Cache:
This tool caches your posts, pages, CSS and JavaScript code, and feeds (categories, tags, comments, and search results. It also converts your images to the modern WebP format so they’re quicker to load.
Another good caching plugin is WP Super Cache:
This tool generates static html files of your WordPress blog. These files will then be served to the majority of your users, including those who are not logged in and those who have not left a comment on your blog.
Some of your visitors will be served custom cached files, based on their interactions on your site.
For example, logged-in users and those who have posted a comment will see a different cached version of your site.
2. Enable Browser Caching
Browser caching stores static content like images, CSS, and JavaScript files on your visitors’ devices.
When a user returns to your site, their browser will retrieve these assets locally instead of loading data from the server again.
Some WordPress optimization plugins like the ones mentioned above will offer browser caching. However, you can also enable this manually.
If your WordPress website runs on an Apache server (you can check this with your hosting provider), you’ll just need to edit the .htaccess file to enable browser caching.
You can access this file through the File Manager in your hosting account, or by using a file transfer protocol (FTP) client like FileZilla. It’s located in your site’s root directory, which is usually called public_html or www.
Then, open the file and add the following code at the bottom:
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType text/html "access plus 1 hour"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
</IfModule>
Finally, save your changes and re-upload the file to the server if needed.
If your WordPress site is hosted on an Nginx server, you’ll need to modify the server configuration file. In this case, we recommend asking your hosting provider for assistance.
3. Implement a Content Delivery Network
A content delivery network (CDN) stores copies of your website on a network of servers distributed around the world. Then, when someone visits your site, it delivers the content from the server that’s closest to their location.
This reduces the time it takes for content to travel between the server and the user. As a result, it is delivered more quickly.
Popular CDN services include Cloudflare, Amazon CloudFront, and Akamai:
However, before you implement a CDN caching solution, you’ll want to check that you don’t already have this tool installed as part of your hosting plan.
4. Choose a Web Host That Offers Server-Side Caching
Server-side caching stores pre-rendered versions of your content directly on the web server.
Instead of dynamically generating pages for each visitor, the server serves cached web content to make your site faster.
Many reputable hosting providers like NameHero offer server-side caching as part of their plans:
With NameHero, this caching solution is built into the LiteSpeed web server. However, you’ll also need to install the LiteSpeed Cache plugin on your WordPress site:
Once you’ve installed the plugin, you’ll need to make sure that server-side caching is enabled.
Go to the cPanel in your hosting account and under the Advanced section, click on LiteSpeed Web Cache Manager.
This will take you to a page where you can configure your caching options. Scroll down to the LiteSpeed Cache Management section and you’ll find the cache for your particular web application. In your case, this is WordPress.
If you click on it, you’ll be able to manage the LiteSpeed cache on your WordPress website.
Note that LiteSpeed caching is available on all NameHero plans, including WordPress and WooCommerce hosting.
Conclusion
Caching is a powerful solution for speeding up your website and ensuring an optimal user experience. It works by storing copies of your content on the user’s browser or your site’s server, and loading them to repeat visitors.
To recap, here are four caching strategies that you can use to improve your site’s performance:
- Use a caching plugin like W3 Total Cache or WP Rocket.
- Enable browser caching.
