The Beginner’s Guide to SSL Certificates for Your Website
What Is an SSL Certificate?
SSL stands for Secure Sockets Layer.
It is a small data file that creates a secure link between your website and your visitors’ browsers.
When a website has an SSL certificate, the connection is encrypted. That means anyone trying to intercept the data sees only scrambled nonsense, not readable information like passwords or credit card numbers.
You have probably noticed the little padlock icon in your browser’s address bar when you visit certain websites. That padlock means the site has an SSL certificate. In fact, most browsers now mark websites without SSL as ‘Not Secure’, which can scare visitors away before they even see your homepage.
Why Does Your Website Need SSL?
There are three big reasons to add an SSL certificate to your website.
Security
SSL encrypts the data passed between your website and your visitors. If someone submits a contact form, signs up for a newsletter, or makes a purchase, SSL keeps that information private.
Trust
The padlock icon and the ‘https’ in your web address tells visitors that your site is safe to use. People have been trained to look for it. Without it, many will leave.
SEO
Google uses SSL as a ranking signal. Websites with SSL certificates rank higher in search results than those without. It is one of the easiest ways to give your site a small but meaningful SEO boost.
SSL, TLS, and HTTPS: What Is the Difference?
You will see SSL, TLS, and HTTPS used in similar contexts. Here is the short version:
- SSL was the original technology, developed by Netscape in the 1990s.
- TLS (Transport Layer Security) is the newer, more secure replacement. But everyone still calls it SSL because the term stuck.
- HTTPS (HyperText Transfer Protocol Secure) is what you get when a website uses an SSL/TLS certificate. The ‘S’ stands for ‘Secure’.
So, when you buy an SSL certificate, you are usually buying a TLS certificate. And when your site uses HTTPS, it is using that certificate to encrypt traffic. Simple enough.
Types of SSL Certificates
There are three main types of SSL certificates, each offering a different level of validation.
Domain Validation (DV)
This is the most common and most affordable type. The certificate authority checks that you own the domain. DV certs are issued quickly and are fine for most small business websites and blogs. UK2 includes unlimited DV certificates for free.
Organisation Validation (OV)
The certificate authority checks your domain and your business details. OV certs show your company name in the certificate details. They are a step up for businesses that want extra trust signals.
Extended Validation (EV)
This is the highest level. The certificate authority does a thorough check of your business before issuing. EV certs turn the browser address bar green (on some browsers) and show your company name. They are mostly used by large organisations, banks, and e-commerce sites.
How Google Chrome’s SSL Change Affects You
Since 2017, Google Chrome has marked HTTP pages as ‘Not Secure’. That was a major push that got millions of website owners to switch to HTTPS. More recently, Google and other browser makers have shortened the maximum lifespan of SSL certificates. As of March 2026, certificates are valid for a maximum of 200 days instead of the old 398-day limit. This means you need to renew your SSL certificate more often. But if you use a hosting provider that handles this automatically, you will not notice any difference.
How to Get an SSL Certificate for Your Website
You can buy SSL certificates from many places, but the easiest way is to use a hosting provider that includes them for free. Every UK2 web hosting plan comes with unlimited free Let’s Encrypt SSL certificates. They are installed automatically, so you do not need to do anything technical. The certificate, the encryption, and the padlock icon all work out of the box.
Here is what you need to do:
- Sign up for a UK2 hosting plan; shared hosting or WordPress hosting both include free SSL.
- Point your domain to your UK2 hosting (UK2 helps with this during setup).
- UK2 installs and manages the SSL certificate for you automatically.
That is it. No extra steps, no technical knowledge needed, and no extra cost.
Frequently Asked Questions
Can I get an SSL certificate for free?
Yes. UK2 includes unlimited free Let’s Encrypt SSL certificates with every web hosting and WordPress hosting plan. There is no extra charge, and they are installed automatically.
What happens if my website does not have SSL?
Visitors will see a “Not Secure” warning in their browser. This damages trust, reduces the chances of someone filling in a form or making a purchase, and hurts your search engine rankings.
Do I need SSL if I only have a simple information website?
Yes. Even if you do not collect payments or personal data, SSL protects your visitors’ privacy and improves your SEO. Plus, most visitors now expect to see the padlock icon.
What is the 200-day SSL change?
From March 2026, SSL certificates have a maximum validity of 200 days instead of 398. This means certificates expire faster. UK2 handles automatic renewals for you, so you do not need to worry about it.
Is SSL the same as HTTPS?
Not exactly. HTTPS is the secure version of HTTP that uses an SSL/TLS certificate. When you have an SSL certificate installed, your website can serve pages over HTTPS. You need the certificate to get the padlock.
Can I install an SSL certificate myself?
If you have technical experience, you can. But UK2 installs and manages SSL certificates automatically on all hosting plans. You get the security and the padlock without lifting a finger.
