Use the Hostinger Cache Manager

One good place to start Hostinger Site Optimization is the Cache Manager. You must log in to Hostinger hPanel and head to the Advanced menu. Over there, you need to look for the Cache Manager. After you find it, the next best thing you can do is ensure the Automatic Cache toggle is on. The Cache Manager also gives you the option to purge a specific URL.

It gives you the convenience of managing different aspects of performance from within a single plugin. Premium caching plugins have many advanced features you don't get in free caching plugins.

While free caching plugins provide only caching, Premium Caching plugins offer more optimization options such as advanced caching, image optimization, CDN, gzip compression, and database optimization. Hence, it's always worth paying for a premium caching plugin.

Uninstall Unwanted & Slow Load Plugins

Sometimes, we leave unnecessary plugins on our WordPress dashboard even if we don't use them. Such plugins can add to the overall size of the website and affect its performance. Besides, some plugins may be helpful yet bad from a performance perspective. It's essential to address both issues in time. You can start by closely examining your WordPress plugins section and determining which plugins are useless for your site. After you decide on this, you can remove the unnecessary plugins immediately, improving your site speed to a certain extent.

After Gtmetrix finishes scanning your site, you need to get to the Waterfall section and check if there is any plugin taking too long to load. If you find one, you may replace it with a suitable alternative. However, after making the changes, you must scan your site again with Gtmetrix to see if the plugin loads faster than the previous one.

Remove Unused CSS & JS

Sometimes, the Hostinger WordPress site can be slow due to the unused CSS and JS. Hence, it's essential to ensure the scripts load only when needed. For example, a plugin like Contact Form 7 loads its CSS & JS scripts on all pages, including the Homepage, even when you use the plugin only on the contact us page. This is where a plugin like PerfMatters comes in handy.

PerfMatters gives you the option to remove the script from different pages. After installing this plugin, you will get a Script Manager to remove the script at the top bar of all pages. PerfMatters is a paid plugin, and it's worth paying for it since it comes with many other advanced functionalities. However, if you need a plugin only for removing the script from pages, you can use an excellent free alternative such as WP Asset Clean Up.

Enable Image Optimization

Most WordPress website uses images, which can affect your site speed if not optimized. Hence, this may not be ideal for everyone, and you may need an auto image optimization service. Unless you compress images, they can have a large size. There are a few ways to go about it. You can compress images manually using free online compress services, but it can take time.

Many CDN claim to do image optimization, but they don't put enough emphasis on this aspect. That's why it's essential to use a dedicated WordPress image optimization. There are many good free and paid WordPress image optimization plugins. Almost all image optimization plugins these days come with WebP format, which can drastically reduce the size of images. WebP format gets your images 20x lighter than PNG.

Another advanced way of image optimization is using an image CDN plugin like WP Compress. The plugin optimizes images through Google CDN and Bunny CDN. Optimizing images will undoubtedly improve your site speed to a large extent.

Delay JavaScript Execution

Technically, all the scripts don't need to load in the initial time, and that's where Delay JavaScript Execution comes into play. Some scripts, such as live chat widgets, Analytics scripts, or Facebook pixels, can be delayed and prevented from loading in the initial time.

That will help your site content load faster, and the scripts will be loaded as visitors reach certain sections of the page. Delayed JavaScript Execution can immensely also enhance the Largest Contentful Paint score.

Use Prefetch DNS Requests

It's time to familiarize you with another advanced performance optimization technique called Prefetch DNS Requests. When you use Prefetch DNS Requests, it gets your site's external files to load faster. It's especially ideal for mobile networks. Most premium caching plugins come with the feature. is a free tool to determine what domains you can add to the Prefetch DNS Requests. You can add Google analytics, fonts, and other external requests to Prefetch DNS Requests. Once you start using this option, you will undoubtedly see good improvement in the Core Web Vitals of your Website in a few days.

Speed Up Your WordPress Site with PerfMatters

Wouldn't it be nice if we could control the performance optimizations with just a single plugin? Fortunately, such plugins do exist. PerfMatters is one such plugin. The plugin is lightweight, with no JavaScript on the site's front end, and comes with many advanced optimization features.

PerfMatters helps your site's performance by reducing HTTP requests and optimizing databases. The plugin can strip code and help you disable plugins with much ease. Other features include Lazy loading, Preloading resources, Delay JavaScript, and Unused CSS Removal.

However, it would be best if you remembered that sometimes there could be issues on the hosting provider's end, and in such cases, there is hardly anything you can do about it.
