If you are a WordPress user, then you have heard the name Really Simple SSL plugin. Really Simple SSL lets you automatically detect your settings, configure your website to run over HTTPS, scan mixed content, secure cookies, and so on.

Among the hundreds of thousands of published WordPress plugins, it is one of the few that have already received more than 4 million active installations yet to date. Yeah! You heard it right.

However, why do users think that the Really Simple SSL plugin is reliable for the WordPress website?

To answer this question we are going to look more deeply in such as performance, simplicity, consistency, pros and cons, features, and limitations. So, let’s get started!

The Role That Really Simple SSL Plugin Plays In Your WordPress Website

Really Simple SSL plugin

In 2018 Google announced a plan to improve overall web security by encouraging website owners to switch from HTTP to HTTPS. As part of this plan, their popular Chrome web browser started marking the websites without an SSL certificate as “Not Secure.”

Google also said that websites with SSL would also see SEO benefits and higher rankings.

You might have noticed that when you visit an HTTP website using the incognito window, it marks as Not Secure. When you visit an HTTP website in regular mode and try to fill out a contact form or another form, then the website is marked as insecure.

When your readers and customers see this notice, it gives them a bad impression of your business. This is why all websites need to move from HTTP to HTTPS and install SSL immediately. Not to mention, if you want to accept payments online on your eCommerce website, then you need SSL.

In general, an SSL plugin will automatically:

  • Redirect all incoming requests to HTTPS
  • Change the site URL and home URL to HTTPS
  • Fix the content that is replaced from http:// urls to https:// 
  • Handle all SSL issues you might have on the website

These are the important things that Really Simple SSL plugin can handle for your WordPress website.
