• Get application security done the right way! Detect, Protect, Monitor, Accelerate, and more…
  • Site speed is crucial for growth but is often overlooked.

    Imagine all that hard work you put into writing content and setting up your site, only to be pushed aside by your competitors. Though there may be a lot of factors behind it, one such factor is site speed. Irrespective of the country or the device your reader is using, your site NEEDS to load as fast as possible to make them stick around.

    Not only does it help in gluing the readers, but it also is a ranking factor for search engines. If your site speed isn’t up to the mark, it’s very unlikely you’re going to rank higher.

    So, what really is hampering your WordPress site speed?

    Well, it could be several factors, and some of the most common ones are discussed below.

    Too many plugins installed

    While plugins are necessary to some extent, having too many of them makes your site bloated and decreases the speed. It’s easy to be tempted by the functionalities of plugins because they reduce manual work, but if it’s sacrificing your speed, then it’s not a good idea.

    Often half of the plugins are just sitting there collecting dust. So, start by identifying what plugins you do not need and remove them.

    Images aren’t optimized

    It’s a good practice to include a ton of images within articles because the readers and as well as the search engines like it. However, what’s not okay is, adding images to your site without compressing/optimizing them.

    No matter how impressive an image is, if it’s anything over 200-300KB, then it needs to be compressed. Compressing images decreases the size while hardly losing any quality.

    Compression/optimization can be done quickly with the use of specific plugins mentioned in this article. I’ll get to that in a bit.

    Server response time is slow

    There are times when you’ve done everything you could, but the problem lies somewhere else. In this case, it might be your hosting provider. Some of the hosting companies out there severely restrict how much speed they can give you, making it impossible for you to improve your site speed.

    A possible solution would be to contact them regarding this or simply change your hosting provider.

    PHP version is outdated

    Keeping things up to date is the best way around fixing problems, so why not start with your PHP version?  Since it’s the underlying programming language of all WordPress sites, using its latest version can most probably help in increasing your site’s speed.

    Supplementing to the above tips, you need also to use certain plugins to increase the speed of your site further. Let’s have a look at them.

    WP Rocket

    Labeled as the “most powerful” caching plugin by WordPress experts, WP Rocket is really essential to boost your site speed. It’s super easy to install and gets activated instantly, eliminating any unnecessary struggle.

    This plugin does a bunch of tasks in the background without you having to do anything, such as:

    • Reduces the weight of your CSS, HTML, and JavaScript

    • Simulates a visit to preload the cache

    The interface is quite simple and their support team is ever-ready to solve any of your problems.

    One of the great features of PRO is CDN. Smush will serve the images from their fast CDN without the complexity of DNS changes.

    WP Super Cache

    PHP scripts are a lot heavier than HTML, and keeping that in mind, WP Super Cache helps in improving your site speed. It generates static HTML files from your dynamic blog and shows that to your visitors instead of the full-fledged heavy one.

    Upon configuration, it also clears the unwanted cache to speed things up. Another very interesting feature is “preloading”. The plugin automatically visits your site’s pages and generates a preloaded version of it to your visitors, so that it doesn’t have to load all over again every time.

    Just like that, there are quite a few more features like this that are aimed at achieving a better site speed.

    W3 Total Cache

    Another great caching plugin, W3 Total Cache. It has over a million installs and does best what it is known for – increasing site speed via caching.

    This plugin is totally free and open-source and can be integrated with a CDN to drastically improve things. It works well on mobile as well, which means the visitors would get the same benefits they’d get on a desktop.

    WP Fastest Cache

    Most of these “cache” plugins have similar names, and WP Fastest Cache is no different in that case. So, it’s easy to get confused between them; however, this plugin does have a bunch of unique features that make it stand out.

    EWWW Image Optimizer can help you increase site speed, save storage, and bandwidth all together. Upon installation, this plugin will optimize all your pre-loaded images and as well as the new ones. It has a smart technology that identifies if your image needs to be converted to another file format for better speed, and it does that for you if you wish.

    You can be sure your images don’t lose any quality in the process, and the best part is, it doesn’t take forever to optimize a ton of images, thanks to their in-server optimization.
