One of the disadvantages of WordPress is that it does not optimize website speed automatically. It appears that it is up to the user to take measures to boost the performance of the WordPress website he owns. As a WordPress user, there is much you can do to speed up your website, tune it for better performance, and optimize it. By putting wise efforts in the right direction, you can get optimal functionality with your WordPress website.
Why is performance optimization necessary? First of all, if your website is not having a reasonable speed (in other words: if your website is slow), then Google will not favor it in the search results. Secondly, users hate websites that perform poorly. And third, you will have much trouble maintaining a website that does not perform well. Thus, it is beneficial for everyone that you optimize the performance of your website.
How can you boost the performance of your website?
There are a couple of things you can do. We will discuss the most significant changes you can make right away without using any WordPress plugin. Then we will review a couple of great plugins that can help you with the performance optimization task. Here, we have gathered a list of 10 best plugins that can help you take your website’s performance to top gear.
Let’s get started.
The First Step of Optimization: Find out where you stand
Before you begin with the task of boosting your website performance, you should check how optimized your website already is. There should be a reference point so that you will know how much you need to improve.
Luckily, there are a few plugins that can give you a reference point about the current performance ranking of your website. These are some of the popular speed test tools. These speed test tools analyze your website for performance and speed and give you a reference score for these parameters. You can safely assume this score as your starting point and set a target score to achieve through optimization. This way, you know clearly where you stand and where you need to go. Once the goal is clear, strategies, and tools to achieve the goal are easier to align.
Run the performance tests on your site using these tools and get a reference score. Along with the performance score, these sites also give suggestions to improve and recommendations of proven strategies that improve performance. Note these down as these will help you to understand how you can improve your website performance.
Apart from these performance metrics, there are some basic things that contribute to a well-performing website. Let’s have a look at these factors.
Basic Factors for High Performance
Optimizing a website for high performance is like creating a beautiful house. You have to erect strong walls, a water-proof ceiling, necessary amenities, and a bit of decoration. All these represent tasks that WordPress plugins can do. There are plugins for security, functionalities, and ease of use. There are themes for customization. Together, they can build a beautiful house – only if the foundation is strong. Without a solid foundation, the house will not hold strong. Similarly, there are some factors that should be optimized from the beginning. What are these factors?
Here are the factors that you should optimize right from the beginning:
A Good Web Host: Make sure the web host you are using is delivering optimal performance. An average web host that is not able to handle your web traffic and seldom meeting your resource need is a recipe for disaster. If possible, get managed WordPress hosting as these types of hosts focus on speed and performance. You can choose a high-performance host like Nestify that specializes in delivering lightning-fast speed. Using other optimization techniques can not give you optimal results If your web host is not up to par.
An Optimized Theme: Many performance factors of a WordPress website are directly related to the WordPress theme you are using. A WordPress theme not only determines the layout, the design, and the appearance of the website but it also contributes to the performance of the website. Choose lightweight, minimal, speedy, and responsive theme for a website that loads fast.
Choice of Plugins: Having too many plugins will not only slow your site down but it will also cause plugin conflicts which may become hard to trace. Have only the essential plugins and keep them updated. Never install two or more plugins for the same functionality. When you have multiple plugins doing the same task, they will eventually mess up with each other. A poorly coded plugin will surely hamper your website’s performance. Choose plugins wisely and check them often.
After getting these three factors right, it is time to use WordPress optimization plugins. Here we have curated a list of some of the best WordPress performance optimization plugins.
