What is SSL?

SSL (Secure Sockets Layer) signifies a secure entry layer. SSL is the process of encrypting data during server-client communication. Its most known use is encrypting the communication between the server and the web browser during data exchange on a website.

Many sites use SSL for secure data communication. SSL consists of a standard algorithm. For SSL to work, there must be a key on the server side and a certificate to operate on the client side.

Features of SSL

  • SSL ensures security and privacy during the encoding of incoming data and decryption.
  • SSL guarantees that the sender and receiver of the data are correct. S
  • SL facilitates the creation of a document archive.
  • SSL verifies the date and time of transmitted documents.

How Does SSL Work?

SSL is based on a coding method that uses keys known as Public Key / Private Key. There are two keys for SSL coding. These keys are digitally encoded software.

Data locked by one key can only be opened by the other key. After creating your keys (SSL does this by default, no action is required from you), one key (private key) stays with you. The other key (public key) is sent to the person you want to connect with.

The person wanting to communicate with you uses the public key to send the message securely. Even if the data is intercepted during transfer, the private key you hold is required to decrypt it. Depending on the type of SSL, 40-bit or 128-bit encryption is used. Decrypting such complex encryption would take a lot of time, even with advanced techniques.

In short, SSL ensures the secure transfer of data between computers exchanging data, preventing any third-party intervention.

Types of SSL Certificates

RapidSSL

RapidSSL certificates are signed with the private key of the “Equifax Secure Global eBusiness CA-1” Certificate Authority Root certificate. This certificate is present in the certificate store of all current operating systems, eliminating the need for intermediate trust authorities’ certificates to be installed in the system like with Comodo and some other providers. It is a single root certificate.

ThawteSSL Certificates

Thawte SSL123 is the fastest and most economical solution for e-commerce sites, web-based email, and other applications that require a site security seal at the entry-level.

QuickSSL Certificates

QuickSSL Premium is the fastest and most economical solution for medium-sized e-commerce sites, web-based email, and other applications that require secure communication at a mid-level prestige need and do not require a high level of security.

The Impact of SSL on SEO

Google has started to prioritize the mobile versions of sites over desktop versions with the concept of mobile-first indexing, as the fact that 70% of traffic to websites comes from mobile traffic speaks volumes. Therefore, Google has learned that the mobile versions and appearances of sites will play a significant role in search criteria and will primarily consider the mobile site as the criterion. Google recently announced that websites using the HTTPS protocol would be considered more reliable and that the impact on SEO would continue to increase over time.

Transition from HTTP to HTTPS

Information was provided in Search Console regarding the transition to HTTPS. Last week, Google conveyed a message to site administrators in the Webmaster Search Console about SSL. The message stated that from October 2017, Google Chrome would show warnings on sites without SSL. In short, Google has taken another step towards making SSL certification mandatory.

The message in the Webmaster Search Console;

related to this announcement, you can clearly see that HTTPS is recommended on the Search Console help page. Additionally, you can find information about the use and implementation of HTTPS.

What Should We Pay Attention to When Switching from HTTP to HTTPS?

When Integrating an SSL Certificate into Your Site Be Careful Incorrect or incomplete procedures can lead to motivation loss and financial losses.

  • The entire site should be transitioned to SSL without loss.
  • SSL redirection should be done with a 301 permanent redirect.
  • The standard certificate has 128-bit and 256-bit data encryption capabilities. If you do not have a comprehensive and large site, you can use a standard SSL.
  • A Wildcard certificate can cover all your subdomains along with your site. If you have a large and comprehensive site, you should use Wildcard SSL.
  • The validity period of the SSL certificate is important. It should be extended before it expires. The certificate should be obtained for the used address.
  • After switching to SSL, if you use Google Analytics, do not forget to update the “Default URL” section in “Admin – Property Settings” to “HTTPS”.
  • Check your Sitemap.xml and Robots.txt.
  • Add the SSL-certified version to the Search Console. However, most sites have a canonical structure that is inherent to their pages. Therefore, after switching to HTTPS, set up your Search Console settings and do not delete the HTTP structure for a while. When you search for “SSL Test” on Google, many SSL test platforms appear.
  • You can test your SSL through these platforms. Do not forget to check the “Crawl Errors” section in the Search Console more frequently after switching from HTTP to HTTPS to see if there are any SSL-related errors.

Can There Be Free SSL?

This section shall be a bonus and gift section. Can there be free SSL even when backed by big companies like Cisco, Mozilla, Chrome? Indeed, there can be. LetsEncrypt comes to the rescue for those who do not want to pay for HTTPS. As always, we wanted to share this with our readers and fans.

This application, while it may put personal ventures in difficulty, is thought to contribute to creating a cleaner and spam-free internet world.

Even if competing sites have not switched to HTTPS, you can take a step ahead by switching as soon as possible.
