As a digital marketer, you know that your website is the face of your business. It’s the first impression that potential customers get of your company, and it’s where they go to learn more about your products or services. But did you know that your website could be putting your customers at risk? That’s where SSL certificates come in. In this article, we’ll explore what SSL is, why it’s important for website security, how it can improve your SEO, and how to install and maintain it on your website.
What is SSL and how does it work?
SSL stands for Secure Sockets Layer, but it’s now been replaced by Transport Layer Security (TLS), which is essentially the same thing. SSL/TLS is a protocol that encrypts the data that’s transmitted between a website and its visitors. This encryption ensures that no one can intercept or read the data while it’s in transit.
When you visit a website that uses SSL/TLS, your browser will initiate a handshake with the website’s server. During this handshake, the browser and server will agree on a set of keys that will be used to encrypt and decrypt the data that’s transmitted between them. Once the handshake is complete, all data that’s transmitted between the browser and server will be encrypted and secure.
The importance of SSL certificates for website security
SSL certificates are important for website security because they ensure that data is transmitted securely between the website and its visitors. Without SSL, data can be intercepted and read by anyone who has access to the network that the data is transmitted over. This means that sensitive information, such as passwords, credit card numbers, and personal information, can be stolen by hackers.
SSL certificates also help to prevent phishing attacks. Phishing attacks are when hackers create fake websites that look like legitimate websites in order to trick people into entering their personal information. SSL certificates can help to prevent these attacks by verifying the identity of the website’s owner.
How SSL certificates can improve your SEO
In addition to improving website security, SSL certificates can also improve your SEO. In fact, Google has stated that SSL is a ranking factor in their search algorithm. This means that websites that use SSL will rank higher in search results than websites that don’t.
SSL also helps to improve user trust. When visitors see the padlock icon and “https” in their browser’s address bar, they know that their data is being transmitted securely. This can help to improve user trust and increase the likelihood that visitors will convert into customers.
Common misconceptions about SSL certificates
There are a few common misconceptions about SSL certificates that are worth addressing. One of the biggest misconceptions is that SSL certificates are only necessary for e-commerce websites. While it’s true that e-commerce websites deal with sensitive information, such as credit card numbers, all websites can benefit from SSL.
Another misconception is that SSL certificates are expensive and difficult to install. While it’s true that some SSL certificates can be expensive, there are also free SSL certificates available from Let’s Encrypt. Additionally, many web hosts now offer easy, one-click installations of SSL certificates.
Types of SSL certificates
There are three types of SSL certificates: Domain Validated (DV), Organization Validated (OV), and Extended Validation (EV). DV certificates are the easiest and quickest to obtain, as they only require verification of domain ownership. OV certificates require additional verification of the organization that owns the domain, and EV certificates require the most extensive verification process.
For most websites, a DV certificate is sufficient. However, if you’re running an e-commerce website or dealing with sensitive information, an OV or EV certificate may be necessary.
How to install an SSL certificate on your website
The process of installing an SSL certificate on your website will vary depending on your web host and the type of SSL certificate that you choose. However, most web hosts now offer easy, one-click installations of SSL certificates.
To install an SSL certificate, you’ll need to generate a Certificate Signing Request (CSR) on your web server. You’ll then need to submit the CSR to a Certificate Authority (CA) to obtain the SSL certificate. Once you’ve obtained the SSL certificate, you’ll need to install it on your web server.
Best practices for maintaining SSL security
Once you’ve installed an SSL certificate on your website, it’s important to maintain its security. Here are a few best practices for maintaining SSL security:
- Keep your SSL certificate up-to-date. SSL certificates typically have a lifespan of one to two years. Make sure to renew your SSL certificate before it expires.
- Use strong encryption. Make sure that your SSL certificate is using strong encryption, such as TLS 1.2 or higher.
- Monitor for vulnerabilities. Keep an eye out for any vulnerabilities in your SSL configuration and patch them as soon as possible.
Frequently asked questions about SSL certificates
Here are a few frequently asked questions about SSL certificates:
- What’s the difference between SSL and TLS? TLS is the successor to SSL and is essentially the same thing.
- Can I use SSL on a shared hosting plan? Yes, most web hosts now offer easy installations of SSL certificates, even on shared hosting plans.
- Do I need to renew my SSL certificate every year? Most SSL certificates have a lifespan of one to two years and will need to be renewed before they expire.
