What is HTTPS? Here’s All You Need to Know 

In the early days of web development, SEO professionals primarily dealt with HTTP, a protocol used to serve web pages to users. During that simpler era, website migrations typically involved moving from one domain to another or from one server to another. It was a straightforward process, mainly requiring standard redirects and meticulous planning to ensure a smooth migration. However, the landscape changed with the advent of HTTPS, paving the way for new considerations for SEO practitioners. 

Let’s begin with understanding what HTTPS is and how it works. 

What is HTTPS? 

HTTPS, or Hypertext Transfer Protocol Secure, is the secure, encrypted version of the standard HTTP protocol. It ensures data privacy and security during transmission between a web browser and a website, guarding against eavesdropping, tampering, and data theft. HTTPS employs encryption through SSL or TLS protocols, as seen in the padlock icon in the browser’s address bar, signifying a secure connection that instils user confidence in data protection. 

How does HTTPS work? 

HTTPS secures internet communication by incorporating security layers known as the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) into the original Hypertext Transfer Protocol (HTTP). These layers encrypt data exchanged between users and websites, ensuring its confidentiality and integrity. 

• Encryption 

When you visit a website using HTTPS, your browser and the website’s server perform an SSL/TLS handshake. During this process, they agree on encryption methods and generate a shared secret key for the current session. This key encrypts and decrypts data as it travels between your browser and the server. Even if the data is intercepted, it remains unreadable. Encryption turns your data into an unreadable jumble of symbols. 

• Authentication 

Websites using HTTPS have SSL/TLS Certificates that contain a public key. This public key verifies that the data you receive from the website comes from a trusted source. Your browser checks if the certificate is valid and if it has been signed by a trusted certificate authority (CA). This authentication process ensures you connect to a legitimate website, not an imposter. 

• Data integrity 

To prevent the tampering of files and pages during transmission, HTTPS adds a layer of data integrity. Each document sent through the secure channel carries a digital signature from the original sender. The receiving website can verify this signature to ensure the data hasn’t been altered in transit. If the signature doesn’t match, it’s a sign that something went wrong during transmission. 

What is the difference between HTTP and HTTPS? 

Both HTTP and HTTPS serve the same function of exchanging data across the internet.  

When HTTP brings information from a server, it lacks security measures, leaving data exposed and open for anyone to read. On the other hand, HTTPS integrates SSL/TLS encryption for secure data transmission, crucial for sites handling sensitive information. 

Here’s a table outlining the differences between HTTP and HTTPS: 

Why and how to switch your website from HTTP to HTTPS? 

To answer the ‘why’ aspect of the question, we’ve listed a few reasons below. 

Security:

HTTPS encrypts data, safeguarding it from eavesdropping and cyberattacks.
 

Data integrity:

It ensures that the information exchanged between users and the website remains intact and unaltered.
 

User trust:

Visitors trust secure sites more, enhancing credibility.
 

SEO benefits:

Search engines favour HTTPS websites, positively impacting search rankings.
 

Compliance:

Many data protection regulations require secure connections. 

Enhanced performance:

Modern HTTPS protocols can improve site loading times. 

Future-proofing:

HTTPS has become the industry standard, essential for online longevity. 

With the compelling reasons to transition your website from HTTP to HTTPS in mind, let’s proceed to the necessary steps for making this conversion: 

1.Back up your website 

Before any modifications, ensure a complete backup of your website. If you use shared hosting, explore available backup options, and if you use cPanel hosting, you may find built-in backup features useful. 

2.Purchase and install an SSL Certificate 

Purchase and install an SSL Certificate to validate your website’s identity and enable encrypted communication between browsers and servers. You can explore several options:
 

• For budget-friendly solutions and quick configurations, choose entry-level or domain SSL Certificates.  
• Organization SSL Certificates require verification but enhance trust by displaying your company’s name in the browser.  
• For the highest trust and security, consider Extended Validation (EV) SSL certificates, which undergo thorough verification and display a green browser bar for a fully secure website. 

Vodien provides a range of SSL Certificate plans, including Standard, Premium+EV, and Wildcard, to accommodate varying budget requirements. You have the flexibility to select the one that best suits your website’s specific needs. 

Each of these plans offers top-tier security, fortifying your website against potential threats from hackers. Furthermore, they employ robust encryption methods to protect sensitive information like banking details, passwords, and email addresses, ensuring the security of both your interests and those of your valued customers. 

3.Update internal and external links to HTTPS 

Ensure all website links are switched from HTTP to HTTPS. If you have a small site, manual updates will suffice, but for larger websites, automated solutions may benefit. Maintain a list of links on social media, email campaigns, or marketing automation to ensure they point to the correct HTTPS URL. 

4.Review code libraries 

If you have a complex website, assess the code libraries. Consult your website’s developer to update any software linking HTTP pages to HTTPS. 

5.Implement a 301 redirect 

Set up a 301 redirect, similar to forwarding mail to a new address, to instantly redirect users to the HTTPS version of your site. This helps maintain your search engine ranking. 

6.Update CDN SSL 

If you utilize a content delivery network (CDN), connect with your provider to update the SSL to align with your new HTTPS site. A CDN stores and distributes copies of your web pages on servers globally and delivers requested pages using the nearest server to the user. 

7.Update Google services 

Update your Google Analytics and Search Console accounts to reflect your HTTPS site. In Google Analytics, modify the default URL to HTTPS. For the Search Console, add a new site with HTTPS for proper tracking and indexing.

FAQs 

1.How can HTTPS prevent cyberattacks? 

HTTPS enhances security by encrypting data between users and websites, protecting URL paths, post bodies, and query strings. While it secures data transmission, it doesn’t function as a comprehensive website firewall. Additional security measures are needed to protect all site information effectively. 

2.Can HTTPS protect against DNS spoofing? 

HTTPS does not directly defend against Domain Name System (DNS) spoofing. While it encrypts data transmission, it doesn’t prevent manipulation of DNS responses. However, combining HTTPS with HSTS (HTTP Strict Transport Security) ensures browsers always connect securely. Even if an attacker attempts a fake version, SSL/TLS Certificates can alert users to potential security breaches, enhancing protection against DNS spoofing.

3.Can HTTPS be used with a VPN? 

Combining HTTPS and a VPN improves website and network security. HTTPS secures data exchanged between users and websites, while a VPN protects the entire device, hiding identity and browsing activity. They create a dual-layered defence for all network users.
