What is SSL and why do you need it?

Each website has an address like webseo.link. If we pay more attention we will see that on the browser no matter how we click this domain name will display it:

http://webseo.link or https://webseo.link

Why is this happening ;

Seeing these indications the user can immediately understand if he is safe while browsing the site he is fooling around with! If on the site you are browsing a user wants to create an account or even place an order via the internet then it is very important to know if their data will be encrypted or if there is a risk that their passwords or even their card will fall to foreigners. hands.

SSL Encryption

So when we see the sign safe on the browser we are sure that the site owner has provided and has protected us to a large extent from the countless hackers that circulate, on the contrary when a site appears with http and not https then we understand that there is no system encryption between the information we send and the server that hosts the site we are on.

Let’s say now that on a website we enable SSL or Secure Sockets Layer.
The pages with SSL enabled stand out from the green padlock on the top left as well as with https: // where the domain name starts.

The “S” at the end of HTTPS means “Safe” and comes from the word “Safe”. This means that all communications between your browser and the website are encrypted. HTTPS is often used to protect highly confidential online transactions, such as online banking and online forms, in order to make purchases.

Web browsers such as Internet Explorer, Firefox, and Chrome also display a padlock icon in the address bar to visually indicate that an HTTPS connection is valid.

What is SSL and why do you need it?

How SSL works

HTTPS pages typically use one of two secure protocols for encrypting communications – SSL (Secure Sockets Layer) or TLS (Transport Layer Security). Both TLS and SSL protocols use what is known as an “asymmetric” Public Key Infrastructure (PKI) system. An asymmetric system uses two “keys”, one “public” key and one “private” key to encrypt communications. Anything encrypted with the public key can only be decrypted with the private key and vice versa. So you understand that it is very difficult to spy.

Why do we have to use SSL on our website?

We choose the SSL Certificate mainly for the security of our website and our visitors. It is necessary for eshop. Each eshop must have a security certificate. It’s something like the safety of our car. As in the car, so on our websites it is now necessary! Every business will have to adapt to this change and embed an SSL certificate on its website.

What information can I transfer to a website & what are the benefits of an SSL?

Below we have some actions that the user transfers data to the site server. With the following examples you will immediately understand what we mean ..

By creating an account in an eshop you transfer your username and password to the server that hosts the eshop you have visited.
Making a payment in an eshop you have to enter addresses, names, cards etc etc in a server .. a website that many times you do not even know if the hosting of this website – eshop is located in a large datacenter here in Greece.
Filling in a support form and writing in, for example, your paypal code for a technician to see is again another way of transferring data through the website of a software support company to a server.

So to protect what we need to do all sites have an SSL certificate. And this is how Google starts and grows its demands on online stores.

A prerequisite for proper operation and safety is to add a Safety Certificate to your eshop.

Google rewards all sites that have an SSL certificate and ranks them in better organic results! This means that very soon all websites will be adapted to provide the best security to their customers. And on the contrary, it means that all the websites that do not care to show a correct image will be deleted from the map … at least the Goolge map!


SSL is also a very importan factor for SEO. It is proven tha Search engines like Google, give high importance to website that use an SSL certificate. Safe pages diserve to have higher ranks in search engines and this is exactly what is happening.

So if you take Search engine optimization seriously, the SSL is an important factor that you should take care of.
