Top 10 WordPress Speed Optimization Plugins

What is the first thing that users notice about websites? The correct answer is “speed.” That’s right, before signing up for a newsletter, finding relevant content, or admiring top-notch web design, they’ll judge website efficiency based on page load times.

People do many things on the Internet, and they hate wasting time because of websites’ poor performance, especially when using mobile devices. The cold truth is that the probability of bounce increases 32% as page load time goes from 1s to 3s.

Let’s see what can be done to speed up WordPress sites without further ado. 

Key Functions of WordPress Speed Optimization Tools

There are many reasons for the slow loading of websites. To address the issues slowing down WordPress sites, users must employ tools with the following functionalities:

  • Caching allows WordPress to create high-speed data storage containing copies of files so that in the future, WordPress can serve data from there instead of retrieving it from the original location. 
  • A content delivery network (CDN) is a storage service that hosts website content in data centers worldwide. The content includes HTML pages, scripts, multimedia files, and more. CDN allows serving content from regional servers (also called Points of Presence – PoPs) for regional users.
  • Minification of resources refers to removing characters from scripts and codes to decrease their size without changing their functions.
  • Image compression makes images load faster by decreasing their size while keeping their quality at an acceptable level. Another image-related process that improves site performance is lazy loading. It defers the loading of media files located outside of a visible part of the web page.
  • Database optimization involves detecting and removing unnecessary files, and improving website performance and user experience. 
  • GZIP compression is a type of data compression used for compressing files before sending them to the end user’s browser. All modern browsers unzip the files automatically.

It is not an exhaustive list of measures for website optimizations, but all of them are absolutely necessary for boosting WordPress performance. Using specialized plugins is by far the easiest way to achieve this. When choosing WordPress speed optimization plugins, remember that they must cover all the issues above.
