WordPress SSL Certificates: What Are They and Why Are They Important?

Moeez — March 1, 2019 5 Minutes Read

Secure Socket Layer, or simply SSL, is a security protocol that encrypts the communication between a web server and a web browser. In this age of web vulnerability, WordPress SSL certificates provide an additional security layer by ensuring that the communication between a web server and a web browser is private.

When you visit a website, you will notice that the URL is either HTTP or HTTPS. The S in the HTTPS refers to the SSL certificate. Good crawlers also take this into consideration when they are compiling SERPS. A website with WordPress SSL certificate is given preference.

Google Chrome started marking websites without WordPress SSL as “Not Secure”. This resulted in visitors avoiding engagement on such websites. Site owners experienced a decline in conversions like sales, subscription, and more.

What is an SSL Certificate?

Secure Socket Layer (SSL) encrypts the transferred data between a web server and a web browser. When you install a WordPress SSL certificate on your website, you will notice your HTTP protocol changing to HTTPS.

How Does a WordPress SSL Certificate Work?

SSL certificate converts your HTTP protocol into an HTTPS protocol by encrypting the data that is transferred from a web server to a web browser. This process of data encryption involves a user submitting information which can include name, credit card number, home address.

This data is then encrypted and transported from HTTPS to your web server. Any attempt of a data breach will not leak out the information because it is encrypted.

Types of WordPress SSL Certificates

Single Domain

Single domain SSL certificates can only be used on a single domain or a single IP address at a time.


Multi-domain SSL certificates can be used on more than one domains.


A Wildcard SSL certificate is used on a single domain but can be extended to multiple sub domains.

Multi-domain Wildcard

As the name suggests, the multi domain wildcard is a hybrid of both, multi domain and a wildcard SSL certificate. This means that the SSL certificate can be used on multiple domains and also multiple sub domains.

Why Do You Need a WordPress SSL Certificate

There are multiple reasons why you would need an SSL certificate but they can be sorted into two categories:

  • Security
  • SEO


There are multiple reasons why you should have an SSL certificate on your website but Security tops the list. HTTPS protocol protects your website by encrypting the data from your web server to your web browser.

WordPress SSL certificates provide authentication. This means that you don’t have to worry about sending your sensitive data to the right server and not an imposter trying to steal your information.

Also, this added security layer gives your visitors a lot confidence on your website. An HTTPS website encourages visitors to enter their sensitive data without any hesitation.

SSL Helps in SEO

As mentioned in the article above, WordPress SSL certificates contribute to your Google SERPs. Google has a responsibility of directing its users to only those websites that are safe to surf and engage.

Having an SSL certificate signals Google that the website is secure and safe enough for you to direct your users. This is why if you don’t have SSL, you won’t be able to rank higher in the Google search rankings.
