What is an SSL certificate?

Since 2014, Google has been in favor of HTTPS for security and classification purposes.

SSL certificate, commonly known as TLS, is a protocol for encrypting Internet traffic and server identification. Creates a public key to protect the site that allows a device to enter the origin server after verifying its identity.

The certificate consists of information such as the domain name for which the certificate was issued, the respective name of the person, organization or device for whom it was issued, which certifying authority issued it, a digital signature of the authority, date of issue, expiration date, public key (private key is kept secret).

These keys are essentially long strings of characters that are used to encrypt data. Such data is decrypted only with the help of a private key and vice versa.

With technology advancing by leaps and bounds, there are modern websites for which a single domain SSL certificate is not enough. The current website consists of several domains, subdomains, and web pages. To apply authentication to such a website, SSL has variations of certificates.

Multi-domain SSL certificate

Multidomain SSL also known as Subject Alternative Names (SANs). Protect multiple domains with subdomains of a single main domain name or multiple domain names. Easily authenticate and secure 250 unique domains (depending on provider) with a single solution. This unique solution helps an organization avoid the hassle of purchasing specific certificates for each domain it owns.

Multidomain Wildcard SSL

Multidomain Wildcard SSL is a cheap and secure certificate for n number of subdomains. The certificate protects the main domain with an unlimited number of subdomains under it. Multi-Domain Wildcard SSL is available in both domain and organization validation. It’s a great option for users who want to secure multiple domains with an unlimited number of subdomains. A wildcard SSL provides full enterprise validation and is trusted by 99.9% of all major browsers.

Unified Communications SSL Certificate (UCC)

Microsoft Exchange and Microsoft Office Communication Server environments use UCC. Efficiently protect up to 100 domains.

Why should you have an SSL certificate for your site?

  1. Data Protection:

Server-client communication has to be protected on a website. Every bit of information is encrypted with an SSL certificate. When dealing with sensitive data like IDs, passwords, etc., SSL protects the information against malicious hacking activities. The indecipherable format of the information is an unbeatable encryption technology.

  1. Identity verification:

SSL provides authentication. When you install the certificate, you must go through a validation process established by an independent third party known as a Certificate Authority (CA). The CA authenticates the identity of the organization, subject to the type of certificate. Once you have proven your identity, your website will receive trust flags that prove your honesty. Users know who they are talking to when they see them.

  1. Excellent search engine results:

Google changed the algorithm to support HTTPS-enabled websites. This has been proven in numerous studies conducted by SEO experts around the world. One such study, conducted by Brian Dean, founder of Backlinko.com, found a strong correlation between HTTPS and higher search engine rankings.

  1. Compliant with PCI/DSS requirements:

Your website must be PCI compliant to receive payments online. The SSL certificate is required to accept online payments effectively.

  1. Earn customer trust:

SSL certificates are essential for client trust, encryption, and authentication. Easily identifiable signs inform users that the data they submit is secure. They can also see your organization details if you have installed an OV or EV SSL. They are much more likely to do business with you or visit your website once they know you are a legitimate entity.


From 2018 onwards, Google started flagging websites that do not have SSL certificates for more secure web browsing. Regardless of the type of website you have, from a personal blog to a shopping portal, SSL is required, and failure to comply can result in a loss of visitors, which no website owner wants to experience.

Therefore, to perform better and rank top in a search engine, an SSL certificate is a must. For a successful business and loyal following, one needs to integrate certain amendments online to gain maximum strength to stay in this constantly changing digital world.
