Is there the best plugin to speed up your free WordPress website?

Yes it is free. The plugins that I am going to introduce to you in this article are each the best plugins to increase the speed of the WordPress site, and they can be considered as a complete pack, for example, it is not that one of the plugins just remembers to optimize photos or caching Focus site data. These plugins are completely free and if you are the first Barton who wants to use the WordPress site speed up plugin, I recommend that you do not use paid versions to get started.

Before introducing the best plugins, it’s best to explain a few basics so that you know very well how these plugins work.

Step 1: Measure the loading speed of the site

We talked about the loading speed between 2 to 5 seconds, but how can we understand the loading speed of the site?

Well, there are many websites in this field that Google PageSpeed ​​Insights and GTmetrix are the best websites for estimating the loading speed of multiple sites. I have some good news ahead.

Regarding the GTmetrix online tool, I would like to point out that after entering your site URL and completing the analysis by GTmetrix, you will be faced with a set of detailed analyzes, many of which may create a point of ambiguity for you. Well, SEO teaching is here to help you; Become a GTMetrix Master with a series of instructional videos and 50 unique articles. Click on the tutorial to speed up the site with the gtmetrix tool to enjoy.

Another point is that the Google PageSpeed ​​Insights site does not open with the Iranian Internet IP and you must log in with a foreign IP. In the page speed fixing address, SEO teaching completely examines and educates Google invoices for you friends, and you can follow them to increase their awareness.

Step 2: Know your WordPress cache

One of the tasks of WordPress site optimization plugins is to increase the advanced cache. But how familiar are you with the concept of cache?

Cache is the same cache, but what is the meaning of cache? This cache stores information and data that will be used in the near future.

Now the same thing applies with WordPress sites. By caching the website, there is no need to process the result of that user request every time (for example, opening the contents of the website is a request) and spend time on it. With caching technology, instead of constantly processing requests, the results of these requests are stored and used when needed.

One of the most common errors you encounter after analyzing site performance in online tools like Google PageSpeed Insights and GTMetrix is the leverage browser caching error. This error goes back to exactly how to cache; Detailed article on cache debugging is dedicated to this issue, which after reading it, you will get more information about the site cache.

Caching is one way to increase the loading speed of the site, but it is not the only way. Read more is waiting for you.

The WP Super Cache plugin is not a complete package like items 1 to 5, but it works professionally on site caching (as we said, basic caching is one of the factors that reduces site load time).

The working principle of SuperCache is that it removes the static HTML file of the site and as a result, your web server provides the HTML file every time instead of heavy PHP scripts. Each cached HTML file can be displayed hundreds of times to site visitors.

Note: The use of compression has a positive effect on the speed and response time of the site. Fortunately, the WP Super Cache plugin has this feature but is not normally enabled; So remember to activate the compress option after installing this plugin.

Lazy loading undoubtedly has a positive effect on high-traffic sites. BJ Lazy Load is a popular plugin in this field with more than 90,000 active installs. This plugin increases the loading speed of the WordPress site, replaces all the images and content of the pages with a placeholder, and as soon as the user approaches the part of the page that is OffScreen, the content is loaded and as a result, the site bandwidth is greatly freed!

After installing and activating the BJ Lazy Load plugin, go to the counter settings and select BJ Lazy Load.

Of course, there is a lot of talk about photo SEO on the SEO teaching website, and it is recommended that you read its articles. Photo optimization is a miracle in website speed.

Advantages of BJ Lazy Load Plugin:

  • This plugin is compatible with the RICG Responsive Images plugin which is used for professional responsiveness of site photos.
  • If you do not want to be lazy to load certain images, you can deduct those images from lazy load by assigning a class to the images and entering those classes in the plugin settings.

10 – WP Smush.it

The use of images in the content is visible to the user and is extremely attractive to him, but what if the size of the photos slows down the site? You know very well that low speed is neither pleasant for the user nor for the search engines. Suppose you are going to learn how to install an application in a post and you have to use a lot of screenshots and images; Normally, their size is not small and on the other hand, you do not want to get a negative score from the search engine due to the high size of the photos. What is the solution? Image optimization.

Image optimization is one of the most important factors in increasing the speed of the site and some software and plugins do this well. Image optimization is not just about quality loss; The purpose is to reduce the size of the image without compromising its visual quality.

WP Smush.it plugin with more than 1 million active installations is a specialized plugin in the field of optimizing and compressing site images. It does not matter what theme or page layout you use to manage your WordPress media library because WP Smush.it is compatible with them all.

And they load noCritical code at the bottom of the site, but these plugins don’t just do that, and all the other things they do, like the Hummingbird plugin we put at the bottom. The plugin is for the same company that designed the great Smush plugin and introduced it above.

  • Hummingbird Plugin – Optimize Speed, Enable Cache, Minify CSS & Defer Critical JS (link)
  • CSS plugin JS Manager, Async JavaScript, Defer Render Blocking CSS supports WooCommerce (link)
  • Critical CSS and Javascript plugin (link)


Buy paid plugins or do we have a good free plugin?

I 100% recommend using non-paid and free plugins, what is the reason? Because initially buying foreign plugins from Iranian sites means complete and organized theft. The owner of the plugin, who is a foreign developer, is not satisfied that we go inside Iran to buy the plugin once and then come and sell it to thousands of people on some sites. If, for example, we do the same with your business, how do you feel? (You get it back from any bad hand, remember this)
So one of the reasons is that it is better to start from the beginning and not to participate in widespread thefts so that this culture is formed in all friends.

The second reason that is very important is that we have a lot of great free plugins in the field of site speed, and above we have listed the best ones for you, and there is no reason to spend at all. Rest assured that if you take the time to review, test, install and finally evaluate the plugins that we introduced to you at SEO teaching, you can find a very good option for your site.

End and important point – know that:

Friends, know that increasing the speed of WordPress site is not limited to installing the plugin! try:

  • Choose the best host for your site
  • Avoid installing unnecessary plug-ins
  • Always optimize site photos as much as possible
  • Categories and other items on your site should be neat and tidy
  • Do not always try to use heavy and graphic widgets on all pages, even simple articles.

In this article, I tried to introduce you to the best WordPress site speed up plugins that are both free and really have a small effect on your site speed. Give priority to the first, but each plugin can have a different function on different sites; You can even consult your site hosting support before choosing one of the plugins. Maybe they will introduce you to a special plugin that is more compatible with the host.
