What is a SSL certificate ?
An SSL (Secure Sockets Layer) certificate is a digital certificate that establishes a secure, encrypted connection between a web server and a browser. This ensures that all data sent between the server and the user is encrypted and protected against eavesdroppers and hackers. Websites with an SSL certificate can be recognised by ‘https://’ in the URL instead of ‘http://’, and you will often see a padlock icon in the browser's address bar.
Why is an SSL certificate important for website security?
Data protection: SSL certificates encrypt the data exchanged between the user and the server. This means that sensitive information, such as login details, credit card numbers and personal data, is secure and cannot be intercepted by malicious parties.
For example: suppose a customer enters their credit card details on a webshop. Without SSL, this information could be intercepted by a hacker. With SSL, the data is encrypted and virtually impossible to decode.
User trust: An SSL certificate ensures that users trust your website. The padlock icon and ‘https://’ in the URL show that your site is secure. This increases the likelihood that users will complete transactions and interact with your site.
How do SSL certificates affect SEO?
In addition to security, an SSL certificate also plays a crucial role in your SEO strategy. Here's why:
- Higher Google rankings: Google has confirmed that SSL certificates are a ranking factor. Websites with SSL are ranked higher in search results than websites without SSL. This means that a secure site can generate more traffic through better visibility in search engines.
- Trust and authority: A secure website is seen as more reliable and authoritative. This increases the click-through rate (CTR) of your search results, which has a positive impact on your SEO.
How do you implement an SSL certificate?
Implementing an SSL certificate is a relatively simple process, especially if you have a hosting provider such as Level27 to guide you through the process. These are the basic steps:
- Choose the right type of SSL certificate: there are different types of SSL certificates, such as single domain, wildcard, and extended validation (EV). Choose the certificate that best suits your needs.
Tip: for most small to medium-sized businesses, a single domain or wildcard SSL certificate is sufficient. Larger businesses with higher security requirements may consider using EV SSL certificates. - Obtain the certificate: purchase an SSL certificate from a trusted certification authority (CA). Many hosting providers, including Level27, offer SSL certificates as part of their services.
Tip: look for providers such as Let’s Encrypt that offer free SSL certificates. - Install the certificate on your server: this can usually be done via your hosting provider's control panel. Follow your hosting provider's instructions to install and configure the certificate.
Tip: if you are unsure how to do this, Level27's support team can guide you through the process and ensure that everything is set up correctly. - Force HTTPS: ensure that all traffic to your website is redirected from HTTP to HTTPS. This can usually be done by making a simple change to your .htaccess file or via your web server settings.
Tip: after implementation, check that all pages redirect correctly to HTTPS and that there is no mixed content (insecure HTTP content) on your pages. - Test your installation: use tools such as SSL Labs to test your SSL installation and ensure that everything is working correctly.
Tip: perform regular security checks to ensure that your SSL certificate is up to date and functioning correctly.
