Ultimate Guide to SSL : What it is and Why it is Important ?

What is SSL

Today, in the age of networked information systems, network security is important because globally, people, businesses, corporate etc., depend on network security for storing, accessing and providing business information. This is the reason that the security and privacy of websites have become such a crucial issue. One of the significant aspects of website security is implementing SSL (Secure Sockets Layer) protocols. In this blog, we will learn everything about SSL for the website. We will cover its importance, implementation process, types of SSL certificates, potential issues that may arise, the benefits it brings to SEO efforts and some valuable tools and resources.

What is SSL, and Why is it Important?

SSL is an encryption-based Internet security protocol that provides a secure connection between a user’s browser and a website.

Importance of SSL

Here are several reasons why SSL is necessary for a website:

1. Security Of User Data

SSL encryption ensures that user data such as personal details, login credentials and financial transactions remain confidential and inaccessible to anyone who visits your website. This encryption can protect user information from unauthorized access or cyber-attacks, block anyone outside the website, and create a safe browsing experience.

2. Secure Payment Information

When handling payment information, SSL offers an additional layer of security. Whether processing credit card transactions or facilitating online purchases, SSL ensures that the financial data is encrypted during transmission, reducing the risk of unauthorized access or fraudulent activities.

3. Trustworthiness

SSL certificates help you in building trust with users who use your website. Whenever a user visits your website, they usually look for visual trust indicators that confirm the authenticity and trustworthiness of your website. A padlock icon displayed in the browser’s address bar signifies the presence of SSL and provides users with peace of mind that their information is safe. Furthermore, it establishes user trust and increases the website’s credibility.

4. Avoiding Browser Warnings

If your website doesn’t have SSL, it will display “Not secure” warnings. These warnings are sent to users as a precaution against potential risks in providing information on unencrypted websites. However, these warnings can deteriorate user experience and discourage site interaction. Website owners can prevent these browser warnings using SSL to secure their websites and improve user experience.

5. Boost SEO Ranking

SSL can affect a website’s search engine rankings by increasing the amount of traffic to your website. Search engines like Google promote websites that have SSL and improve their online visibility in search engine result pages. Implementing SSL indicates a website’s dedication to security, which is in line with search engine objectives to promote secure browsing.

Implementation of SSL

The implementation process of SSL on a website involves a series of steps to ensure a smooth transition to secure browsing for website visitors.

Let’s look at the implementation process:

  • Purchase/Obtain certificate: Select a reputable SSL certificate provider and acquire the certification that best suits your needs.
  • Install on server: After obtaining the certificate, it’s time to install it on the web server. Depending on the server software being used, the installation process may vary.
  • Configure web server : Proper configuration is vital to ensure that the SSL certificate functions correctly and that the encrypted connection is established.
  • Update site links to HTTPS: Ensure all of the website’s internal links have been updated to use HTTPS rather than HTTP. This ensures the secure connection is continually maintained throughout the website.

Types of SSL Certificates

Various types of SSL certificates are available in the market, each created to meet a different set of demands and requirements.

1. Domain Validation(DV)

The domain-validated SSL certificate confirms the ownership of the domain and provides encryption for the website.

  • Issues in no times
  • Show visual trust indicators like a padlock icon
  • Validates control of a domain
2. Organization Validation (OV)

Organization validation SSL certificates are a step further from domain validation. OV certificates offer enhanced trustworthiness and are used by businesses.

  • Validate both the domain ownership and the organization behind it.
  • Issues in 1-3 days
  • Enables HTTPS and the padlock image
3. Extended Validation (EV)

EV provides the highest level of SSL validation. Extended Validation SSL certificates undergo rigorous verification of the business’s identity. Websites with EV certificates display the organization’s name prominently in the browser’s address bar, instilling users with a sense of confidence.

  • Shows organization details in the certificate information
  • Issues in 1-5 days
  • Lengthy validation process
  • Provides the visual trust indicators
4. Wildcard SSL Certificates

A wildcard SSL certificate secures a domain and its subdomains under the main domain. It allows for the encryption of multiple web pages under a single certificate.

  • Affordable solution for websites
  • Available as DV and OV validation options
  • Secure unlimited subdomains
5. Muti-Domain SSL Certificates

Multi-domain SSL certificate allows the encryption of multiple domains. They are ideal for organizations with large domains with multiple web properties. Multi-domain SSL certificates are available in DV, OV, and EV validation options.

  • Can secure up to 250 domains with a single solution
  • Save time and money

Potential Issues and Solutions

While implementing SSL can enhance website security significantly, potential issues may need attention.

Mixed Content Warnings

  • When transitioning from HTTP to HTTPS, it is crucial to update all resources on the website using the secure HTTPS protocol.
  • Failure to do so can lead to mixed content warnings due to insecure elements on web pages.
  • To avoid mixed content warnings, website owners should update all resources to use HTTPS. This ensures a secure and seamless browsing experience for visitors.

SSL Certificate Expiry

  • When an SSL certificate expires, a website loses its connection and displays security warnings.
  • Website owners should diligently monitor and renew their SSL certificate’s expiry date before expiration.
  • This proactive approach ensures continuous security and avoids potential downtime and loss of user trust.

Search Engine Indexing

  • When implementing SSL, it is essential to establish proper redirection from HTTP to HTTPS and failure to do so can result in search engines indexing.
  • Website owners should implement permanent 301 redirects from HTTP to HTTPS to prevent such indexing issues.
  • Update the website’s sitemap to reflect the HTTPS URLs, ensuring that search engines crawl and index the secure version of the website accurately.

Benefits for SEO

Apart from the security advantages, implementing SSL can positively impact a website’s SEO performance in various ways.

1. Improved Site Speed

SSL websites can use the HTTP/2 protocol, which offers performance enhancements over its predecessor. HTTP/2 allows faster and more efficient data transmission, reducing latency and improving site loading speed. This contributes to a positive user experience, minimizing bounce rates and enhancing overall SEO performance.

2. Increased User Trust

The increased user trust fosters longer visit durations, lower bounce rates, and greater user engagement, all of which positively impact SEO rankings. Additionally, visual trust indicators like a padlock icon also establish trust with the users

3. Better Analytics

The use of SSL preserves referral data from secure websites. These insightful analytics enable data-driven decisions to improve overall website performance.

Tools & Resources

Implementing SSL can be made more accessible with the assistance of various tools and resources available.
