The term SSL is an acronym for Secure Sockets Layer, which has become the standard technology to keep an internet connection secure. It protects all sensitive data exchanges between two systems, preventing criminals from reading and modifying the information that is transferred.

There was a time when all websites used HTTP. But the HTTP protocol became insecure and was an easy target for both brute force and man-in-the-middle attacks. All the data sent through an HTTP protocol was transferred in plain text from one point to another. This allowed attackers to easily intercept sensitive user data, such as credit card details and account logins.

This is why HTTP(s) was introduced. The information that you send through HTTP(s) is encrypted and impossible to intercept. Therefore, only a sender and a receiver can access the data. Today the majority of websites have replaced HTTP with HTTP(s).

How to Check if a Website has an SSL Certificate?

There are two possible ways to check if a website uses an SSL certificate: manually in the browser or through a program/tool.

For the manual method, open the internet browser and navigate to the website. Check to see if the URL address has "HTTPS" instead of "HTTP". For example, indicates that the website has an SSL certificate and is secure. There is even a tiny padlock in the URL bar. It will show the message "Connection is secure" if you click on it. This guarantees that the communication between you and the company responsible for the website cannot be intercepted or modified.

Types of SSL

There are three types of SSL:

  • Domain Validated (DV) Certificate
  • Organization Validated (OV) Certificate
  • Extended Validated (EV) Certificate

A domain validated SSL certificate offers a low level of encryption. This is recommended for blogs, small business pages, and websites that don’t store information. It requires verification of the site through an email or a phone call made to the site owner. It is the cheapest option and the fastest to obtain.

An OV SSL certificate is used for encrypting user data during transactions. Compared to the DV SSL, an OV SSL certificate has stronger encryption. It helps you distinguish secure (legit) websites from malicious (shady) websites.

How to obtain an OV SSL? First, you need to wait for the certificate authority to investigate your website and determine its rightful owner. Then, you may be asked to submit business documents, bank statements, and domain information from the provider. When you complete this procedure, the certificate will be available in the browser's address bar.

Extended Validation (EV) SSL certificate is the best for online stores (e-commerce). However, you need to undergo a complex and comprehensive verification process to obtain one.

The importance of SSL for an online store

All major and professional websites should have SSL. But is making your website look secure the only reason that you should get one? The answer is no. So let's consider a more thorough explanation.


Since 2014, Google introduced more radical changes to its search engine algorithm and made an SSL certificate an important factor for SEO. But, what does that mean? If your website is not using HTTP(s), i.e. no SSL certificate, your chances to rank higher on Google decreases drastically. The further you are from the top results, the less conversion and money you can earn from your website.


For an online store, you need to make multiple payment methods available to your clients. To receive online payments, your website must be PCI compliant and follow certain criteria. Having an SSL-certified website is one of those key requirements.


Most webshops use an authentication system that enables clients to create their accounts and have a personalized experience. Subscription services like Netflix are a good example of how important it is to have secure authentication because one little mistake can cost you a lot of money.

Login pages are a frequent target for hackers and crackers who use brute-force tools to grab the users' passwords and steal money from their account balance or inflict other forms of damage. However, if your website has an SSL certificate, it makes it very difficult for them to commit these crimes.


Besides the encryption and authentication improvements, clients need to trust you and your website. For example, when they are on your website and searching for something or purchasing from your online store, they should feel completely safe. 

If you install an OV or EV SSL, clients will see your organization’s details and reassure themselves that you are a legitimate entity. This significantly increases the chance that clients will make purchases from you and return to visit your site again.

Red flags

Since 2018, Google has added some new rules related to SSL certificates. If a website has no SSL certificate, Google will instantly flag it and mark it as a suspicious website. Even web browsers such as Google Chrome and Mozilla Firefox display a warning message 'Not Secure' when you try to visit the website. Potentially, in the future, websites without SSL may even get blocked on popular web browsers.
