Back in the early days of the internet, the only way you could check if a website was legitimate or not was by very carefully reading the url. And if you’d somehow got one letter wrong and didn’t realise, you may have put your details into a fake website! Thankfully, these days it’s a lot easier to work out if you’re on Paypal or Puypal, simply by checking the SSL certificate!

So what is SSL? SSL (Secure Sockets Layer) is a certificate that establishes a foundation of trust by establishing a secure connection. It registers your website as “verified”, and helps users to trust your site through the secure connection established. Visitors to the site are assured of its security, browsers provide special cues named EV indicators, which can be visually represented by anything from a branded URL to a green padlock symbol.

To obtain this certification you must create a Certificate Signing Request (CSR) on your server. This process will give you both a private and a public key on your server. The SSL Certificate issuer (called a Certificate Authority or CA). The CA uses the CSR data file to create a data structure to match your private key without compromising the key itself. The private key is never seen by the CA.

1.What SSL is used for?

ISSL is used for websites where you need to enter data that’s private and sensitive – for example, login forms, credit card information, and contact forms. For these kinds of data it’s important to keep personal data safe with an SSL certificate.

For websites where you need to enter private data, encryption ensures user activity cannot be tracked or their info stolen.

  • Data integrity prevents files from being corrupted as they’re transferred
  • More websites are making the switch to it for security reasons as it’s become easier to implement


2. Difference between SSL and HTTPS

An SSL certificate is a product you are actually purchasing and installing on your server, while HTTPS is the result of having that certificate on your server. Having an HTTPS URL is simply an indicator that the site has an SSL certificate.

3.How does it relate to SEO?

An SSL certificate can benefit SEO rankings, boosting your site in search rankings when your website has an SSL certificate. It’s not a huge difference, but it’s one of many factors that Google considers when calculating where in search results your website will land.

  • Better rankings can lead to more traffic

Better SEO rankings can lead to more traffic, which means that:

  • Increased Google Rankings – over 40% of the sites on the first page of Google are HTTPS
  • Google favours SEO sites
  • Increased conversions
  • Increased customer confidence

So there you have it – now you know what SSL is, how SSL relates to SEO rankingsand why you might need an SSL certificate. We hope this blog post was helpful in helping you decide whether to choose an SSL certificate and why it’s important for websites that require a certain amount of security.
