When browsing the Internet, have you ever wondered why some URLs start with http:// while others start with https://?
Maybe you noticed the extra “s” when browsing some websites that require giving over personal information, such as your credit card number.
So, where does the extra “s” come from? And what does it really mean?
Simply put, the extra “s” stands for Security, meaning that your connection to that website is secure and encrypted, and any data you enter is safely shared with that website. The technology powering that little “s” is named SSL (Secure Sockets Layer).
As an Internet user, you always want to see https:// while visiting any site you trust with your essential information. As a marketer, you will want to make sure you have an SSL certificate for your audience.
Find out what SSL certificates are, why they are important, and how you can obtain them with our guide right below.
Let’s get started!
When you land on an insecure website that requires you to fill in a form and submit, the information you enter can be intercepted by a hacker. This information could be anything from your email to details on a bank transaction.
But how do attacks often happen?
Here is one of the most common ways: A hacker places an undetected program on the server hosting a website, which waits in the background until a visitor starts typing personal information. Then, it’ll activate to start capturing the information and send it back to the hacker.
However, when you visit a website encrypted with an SSL certificate, your browser will establish a connection with the webserver, then bind your browser and the server. This binding connection ensures that no one besides you and the website can see or access what you enter.
In technology terms, an SSL certificate is a protocol for servers and web browsers, ensuring that data passed between the two are private. It’s done using an encrypted link that connects the server and browser.
SSL was first developed by Netscape in 1995 for the purpose of guaranteeing privacy, authentication, and data integrity in Internet communications.
Websites that request personal information (e.g., email address, payment information, etc.) from a user, should have SSL certificates on their website. Having one means that the information you’re collecting is private. It also guarantees that when your customers see the padlock and https://, their privacy is safe.

There are several types of SSL certificates. Each certificate can apply to a single website or several websites, depending on the type:
Single-domain. This type applies to only one domain (a “domain” is the name of a website, like www.mageplaza.com).
Wildcard. Like a single-domain SSL certificate, a wildcard one applies to only one domain. Nevertheless, it also includes subdomains of that domain.
Multi-domain. As its name indicates, multi-domain SSL certificates can actually apply to multiple unrelated domains.
SSL certificates can also come with different validation levels. You can imagine a validation level like a background check. The level changes depending on the thoroughness of the check.
Domain validation. This is the least-stringent and the cheapest level of validation. All you have to do is prove you control the domain.
Organization validation. This is a more hands-on process. The Certificate Authorities (CA) directly contacts the person or business requesting the certificate. These certificates are more reliable for users.
Extended validation. This type requires a full background check of an organization before the SSL certificate can be issued.
Here are the key aspects highlighting the importance of SSL certification:
1. Data Encryption: SSL certificates facilitate the encryption of data transmitted between a user’s browser and the website’s server. This encryption ensures that sensitive information, such as login credentials, personal details, and financial transactions, remains confidential and secure from potential eavesdropping.
2. User Privacy Protection: SSL certification plays a vital role in protecting user privacy by securing the transmission of personal and sensitive data. This is particularly important for websites that involve user logins, online forms, and e-commerce transactions, as it prevents unauthorized access to private information.
3. Authentication and Trust: SSL certificates authenticate the identity of a website, assuring users that they are connecting to the legitimate server and not an imposter. The visual indicators, such as the padlock icon and “https://” in the URL, build trust among users, enhancing the overall credibility of the website.
4. Security Against Cyber Attacks: SSL certification provides a layer of defense against various cyber threats, including man-in-the-middle attacks. It ensures the integrity of data by preventing unauthorized parties from tampering with or intercepting the information exchanged between the user and the website.
5. Search Engine Optimization (SEO): Search engines, such as Google, consider SSL as a ranking factor. Websites with SSL certificates are more likely to receive higher rankings in search results, contributing to improved visibility and attracting more organic traffic.
6. Compliance with Industry Standards: SSL certification is often a requirement to comply with industry standards and regulations, especially for websites handling sensitive information, such as those involved in online payments. Adhering to these standards helps avoid legal issues and ensures the security of user data.
7. Protection Against Phishing: SSL certificates make it challenging for attackers to create fraudulent copies of websites for phishing attempts. Users are less likely to fall victim to scams when they see the secure connection indicators provided by SSL.
When you visit a website with an SSL certificate, a few distinct differences are displayed within the browser.
Keep in mind that an SSL-encrypted website always has the extra “s”. As we mentioned above, it stands for “secure.” It should look something like our screenshot below.
The padlock icon can show up on the left- or right-hand side of the URL bar, depending on your own browser. For instance, on Safari and Chrome, it will be on the left.
You can click on the padlock icon to read more information about the website and the company that provided the certificate.
Even if a site has the https:// and a padlock icon, the certificate could still be expired, which means your connection wouldn’t be secure. In most cases, the previous two points can prove that the site is secure. However, if you encounter a site asking for a lot of personal information, it may be worth double-checking to ensure that the certificate is valid.
To find out whether the SSL certificate is valid in Chrome, simply hit Ctrl + Shift + C, click the “»” icon, and choose “Security.” Then, you can see more information about the SSL certificate.
When you are looking to get an SSL certificate for eCommerce website, it’s essential to get the right certificate from the right provider, or CA (the organization that issues the certificate and associated keys). A faulty or improperly installed SSL certificate is no better than not having one at all.
Fortunately, it’s not that difficult to get an SSL certificate. Usually, the process runs as below:
You can get an SSL certificate from:
Before choosing an SSL certificate, you should determine what certificate type you need. Let’s say if you want to host content on multiple platforms (on separate domains/ subdomains), you may need different SSL certificates.
Frequently, a standard SSL certificate will cover your content. However, for companies in a regulated industry - like finance or insurance - it may be worth talking with your IT team to make sure that you meet the specific requirements set within your industry.
The cost of an SSL certificate varies; you can even get a free certificate or pay per month to obtain a custom one. The familiar adage, “You get what you pay for,” definitely applies here. Your choice depends on the type of website and your company. A large financial institution may pay thousands of dollars per year for their SSL certificates, but a blog or online portfolio may not require the same kind of security, so a less expensive certificate will probably suffice.
Furthermore, you should consider the validity period of an SSL certificate. Most standard SSL certificates are available for one or two years by default, but if you are looking for longer-term options, you can choose more advanced certificates with longer-term periods.
SSL is considered the direct predecessor of another protocol called Transport Layer Security (TLS).
In 1999, the IETF (Internet Engineering Task Force) proposed an update to SSL. As this update was being developed by the IETF and Netscape was not involved anymore, the name was then changed to TLS.
Actually, the differences between the final version of SSL and the first version of TLS are not drastic; the name change was applied to signify the change in ownership.
Since they are closely related, the two terms are often used interchangeably and confused. Some people use the term “SSL/TLS encryption” because SSL still has so much name recognition.
