Key factors for choosing a speed optimization plugin

If you install a plugin with unnecessary features, it will become a burden in the future. Some constant features should be considered before choosing the final one. 

Some features you must have in the best WordPress Speed Optimization Plugins. Here is the list of the potential features that you should look for:

• Image optimization: An unoptimized image makes the website slow. Because it is large, you must check whether the plugin offers image optimization.
• Caching: Caching is a way to store data temporarily to reduce loading time for returned visitors. There are many kinds of caching, such as browser caching, database caching, object caching, and more. To boost site speed, you need a plugin that offers caching facilities.
• Minification & Compression: Large and unoptimized CSS and JS files are other reasons a site is slow. Optimization plugins minimize the files by removing unnecessary code and performing inline compression.
• Lazy Loading: Lazy loading means the page content will not load at a time; it will load with the scroll of the visitors. As a result, the first things need time to load properly, which increases the user experience.
• GZIP Compression: GZIP compression is a method of reducing the size of files (like HTML, CSS, JavaScript, JSON, etc.) sent from a web server to a browser. By compressing these files, the time required to download them is reduced, resulting in faster page load times and improved website performance.
• Database Optimization: Database optimization means utilizing your resources properly and removing unnecessary files and media from your storage.

You should also ensure the plugin is lightweight and compatible with all popular themes and plugins. Read customer reviews and learn about customer support. If you have multiple sites, research whether the plugin supports multiple sites. Lastly, visit the plugin’s website to update premium plans.
