Are you looking for the best WordPress speed optimization plugins and tools? Wondering how to make your WordPress site load faster? Then you’ve come to the right place.
Website speed is one of the key factors affecting your site’s growth and success. If your site is fast-loading and smooth, then your visitors may love it and possibly take the required action, like buying a product. But if it’s slow, then they’ll just leave your site and may never come back.
Here, we’ve handpicked the best WordPress performance plugins to improve your website speed. Let’s check them out.
Why Speed Optimization is Important for Your Website?
Before directly getting into the list of speed optimization plugins, let’s discuss why speed optimization is important for every website.
Here, we’re going to explain the 3 most vital reasons why performance optimization is necessary.
i) To Improve User Experperience
Everybody knows how annoying slow loading websites can be. If your site doesn’t load faster, in the meantime your visitor/user will find another website that loads faster.
Hence optimizing your site speed is very important for a great user experience. If your website is fast and smooth, then people may enjoy using it, and hence they may come back to it again and again.
ii) For Conversion Rate Optimization
Website speed significantly affects your site’s conversion rate. Meaning if your site is slow, then your site won’t have a good conversion rate.
The conversion rate is the percentage of users completing a required action. For example, if you run an eCommerce store, then a user purchasing your products is a conversion. Simply, users don’t engage with slow loading sites and hence don’t purchase anything.
iii) SEO Optimization and Better Ranks on Search Results
Website speed is one key Google ranking factor. It means that Google loves fast loading websites and gives preference to them in the ranking order. So, if your site isn’t fast enough, then your site may not get a better rank on Google.
Another way, a faster loading website attracts more users. This helps to engage more traffic to your website. As a result, it’ll optimize your site’s SEO and help you boost your site’s search engine rankings.

ii) Best WordPress Caching Plugins
Caching is storing data and assets elements from the previous user requests and reusing it to speed up the current requests.
For example: Suppose a user requests the web page about “ What is WordPress?”. The data of this page is stored in fast accessing hardware like RAM (Random Access Memory). Later, when other users search for the same page, instead of going to the backend and the database, it is reused from the memory. Which saves a lot of time and helps to load the page faster.

How does a CDN improve website load times?
- We know a CDN is geographically distributed which means that CDN connects the users to the shortest data center. Hence, when the user seeks the answer to their questions on the internet, the nearest data center loads the data faster.

vi. Other Speed Optimization Plugins
Here are some additional plugins you can Install which might help the performance of your site.
1. Heartbeat Control by WP Rocket (Free)
The WordPress Heartbeat API is a great feature that provides a real-time communication protocol between browser and server.
This API function will continuously sync all the data between the server and your WordPress dashboard. It also provides callbacks while receiving data, using AJAX calls.
Furthermore, when you create or edit a post, it provides a function to autosave your post. But this autosave function and real-time notifications can be harmful.
Heartbeat API sends AJAX calls using the /wp-admin/admin-ajax.php file. Each request that executes these PHP files is sent to the dashboard every 60 seconds. And the requests for post edits are sent every 15 seconds.
So, larger requests mean high CPU utilization, and eventually, the high usage of CPU may lead to account suspension. Hence, the Heartbeat API should be limited and this is where Heartbeat Control by WP Rocket plays a huge role.
Heartbeat Control by WP Rocket is a plugin that helps to minimize the CPU usage by managing the frequency of the WordPress Heartbeat API. You can easily limit or even completely stop the activity of Heartbeat API.
But if you don’t want to completely stop the API then you can selectively add rules for specific locations only for e:g dashboard or front-end or post editor etc.

But you only need those assets on the /contact page because you’ve got a contact form on that page. And loading those assets on every page will affect the performance of your site.
Asset CleanUp scans all the pages and detects the assets on each page if it needs to be loaded or not. Also, it gives you the option to select the CSS/JS that isn’t necessary to load. Hence, while editing the posts/pages you can simply select the unnecessary CSS/JS. And the loading time of your site will reduce, which is the ultimate goal.
