The HTTPS protocol protects user data through encryption, increases visitor trust, and improves SEO ranking thanks to Google’s ranking boost. It’s essential for ensuring security, privacy, and a better user experience.
The HTTPS protocol ensures that data exchanged between the user and the website is encrypted and protected from interception or manipulation.
From an SEO perspective, Google has made it clear that the presence of HTTPS is a ranking factor, as it prefers sites that offer secure browsing.
Let’s clarify this concept and the role of the HTTPS protocol. Keep reading!
What is the HTTPS protocol? Discover everything you need to know
The HTTPS (Hypertext Transfer Protocol Secure) communication protocol is the secure version of HTTP, the protocol through which information is transferred on the web.
The final S
stands for Secure, and indicates that all communications between the user’s browser and the website are encrypted and protected.
When a website uses HTTPS, the transmitted data is encrypted using the SSL/TLS protocol, which protects the information by preventing it from being read or modified during its transmission through the network.
This is particularly important when transmitting sensitive data, such as personal information, payment details, or login credentials, for example, to social media.
Here are some key points you need to know about HTTPS:
- HTTPS encrypts data in transit to prevent interception and man-in-the-middle attacks, ensuring that exchanged information remains private and intact.
- The protocol helps verify the identity of the website you’re connecting to, reducing the risk of phishing attacks or counterfeit sites.
- It ensures that the transmitted data has not been altered or corrupted during transfer, maintaining its integrity.
- Google considers HTTPS as a ranking factor for search results, as it prefers sites that provide greater security to users.
- A site with HTTPS has a padlock in the browser’s address bar, which increases user trust in the site.
- Some modern web features, such as the HTTP/2 protocol, require HTTPS.
As you can understand, having the HTTPS protocol is no longer an option but a necessity for any website that wants to ensure security, reliability, and achieve a good position in search engines.

What is the role of HTTPS in SEO
HTTPS not only strengthens the website’s security and trust, but also significantly contributes to its visibility and ranking in search engines. It plays a fundamental role in the overall SEO strategy.
Let’s look in detail at how HTTPS affects SEO:
1. Improves user trust
Users trust sites that use HTTPS more, and have the green padlock in the address bar.
Thanks to the HTTPS protocol, the likelihood of users visiting the site and interacting increases. This reduces the bounce rate and improves other quality signals that influence SEO.
2. For Google, the HTTPS protocol is a ranking factor
Google has officially confirmed that HTTPS is a ranking factor in its search algorithms. This means that websites that use the HTTPS protocol are more likely to achieve better positioning in search results compared to those that don’t use it.
3. Speed and HTTP/2
HTTPS is a requirement for using HTTP/2, a newer and faster version of the HTTP protocol that significantly improves page loading times.
Since site speed is a ranking factor, using the HTTPS protocol improves SEO by enabling HTTP/2.
HTTPS Protocol and Website Security: What’s the Connection?
The HTTPS protocol plays a fundamental role in website security because it establishes a direct link with information protection and user trust.
When a website adopts HTTPS, it implements an additional layer of security through encryption, which is essential for protecting data exchanged between the user and the site.
You can hear how important the use of the HTTPS protocol is directly from Emily’s words at the Chrome Dev Summit 2016. Watch the video below, or move on to the next paragraph if you prefer.
How HTTPS Contributes to Website Security:
- HTTPS encrypts the data sent and received, which means that information such as login details, financial transactions, and personal data are protected from prying eyes. This encryption prevents hackers from intercepting and reading the data, protecting users’ privacy and security.
- The protocol ensures that users are connected to the right website and not to an impostor. This reduces the risk of “man-in-the-middle” attacks, but we’ll discuss this better in the next paragraph.
- HTTPS ensures that transmitted data is not altered or damaged during transfer, ensuring that the user receives exactly the data that the website sent, without unauthorized modifications.
From a security perspective, “the adoption of HTTPS is therefore a key indicator of the seriousness and” reliability of a website.
Users are increasingly aware of these aspects and trust and use sites that guarantee a secure connection, recognizable by the green padlock and the “https” label in the browser’s address bar.

HTTPS Prevents MitM Attacks and Protects Data Exchanged Between Users and Websites
The HTTPS protocol prevents Man-in-the-Middle (MitM) attacks and protects data exchanged between users and websites.
During a MitM attack, a hacker inserts themselves into the communication between a user and a website, trying to intercept or alter the information exchanged. Thanks to the encryption provided by HTTPS, we can counter these attacks!
How HTTPS Helps Prevent MitM Attacks and Protect Data:
- Encrypts communication: HTTPS encrypts data in transit, which means that even if a hacker managed to intercept the data, it would be incomprehensible and therefore unusable.
- Verifies the “site’s identity”: HTTPS provides an authentication mechanism for the website, often through an SSL/TLS certificate, which assures the user that they are connected to the authentic website and not to a fraudulent replica created by a hacker.
- Maintains “data integrity”: With HTTPS, any attempt to alter data during its transfer can be detected and blocked. This way, the data that the user receives is exactly what the website sent.

The Encryption Provided by HTTPS Protects Sensitive Information
When a website uses HTTPS, the data sent and received is encrypted, making it extremely difficult for anyone to intercept the communication, read, or use such information.
Here’s How HTTPS Encryption Protects Sensitive Information:
- Protects data in transit: Encryption ensures that data exchanged between the user’s browser and the website is readable only by legitimate parties. Even if a malicious actor managed to intercept this data, they would only find an encrypted stream, which without the correct key is unusable and incomprehensible.
- Secure Transactions: For online transactions, such as purchases or banking operations, encryption prevents credit card details, financial information, and personal data from being intercepted and used illegally.
- Confidential Communications: In addition to financial information, HTTPS protects the privacy of communications, such as chat conversations, emails, and other forms of online data exchange, ensuring that only the recipient can read the message content.
- Data Integrity: Encryption also helps ensure that transmitted data has not been altered or corrupted during transmission. The information that reaches the recipient is exactly what was sent.
- Authentication: HTTPS helps confirm that the website the user is communicating with is actually the one it claims to be, reducing the risk of phishing attacks or other forms of deception.
Practical advice on how to implement HTTPS on your website
Here are some practical tips on how to proceed:
- The first step is to purchase an SSL/TLS certificate from a “trusted Certificate Authority (CA). There are also free certificates, such as those offered by Let” s Encrypt, which offer a good level of security and are accepted by most browsers.
- Some Google services provide automated management of SSL/TLS certificates, facilitating the security of your sites at no extra cost. These include:
- Google Sites: allows you to create websites and automatically manages SSL/TLS certificates.
- Blogger: for those who create content with Blogger, the platform ensures that blogs are protected with automatically managed SSL/TLS certificates.
- Firebase: this service offers automatic management of SSL/TLS certificates for your apps, ensuring secure communications.

- Additionally, many third-party hosting providers offer similar SSL/TLS certificate management services, often at no additional cost.
- After obtaining the certificate, you need to install it on the web server. The installation process varies depending on the server and hosting you use. Typically, you’ll need to access your server, upload the certificate and private key, and configure the server to use HTTPS.
- Modify your web server configuration to force the use of HTTPS instead of HTTP. This often involves changing server settings and configuring a permanent redirect (301) from HTTP to HTTPS.
- Ensure that all internal links on your site point to HTTPS URLs. This includes links in web pages, CSS, JavaScript, and any other files that may call external resources.
- After implementing “HTTPS, it’s important to verify that everything is working correctly. Tools like SSL Labs” SSL Test can help you check that your site is configured correctly and that the certificate is valid.
- Ensure that the sitemap and robots.txt file reflect the updated URLs (HTTPS) to facilitate correct indexing by search engines.
- If you use Google Search Console, inform Google about the switch to HTTPS. This will help maintain your position in search results.
- After implementation, continue to monitor your site to ensure everything is working correctly and there are no security issues.
By following these steps, you can improve your website’s security, protect user information, and enhance your position in search results, as Google rewards sites that use HTTPS.
The differences between the two protocols HTTP and HTTPS
HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are two protocols used for transmitting information over the internet. They present significant differences in terms of security and data transmission methods. Let’s see which:
- The most notable difference between HTTP and HTTPS is the level of security, which is higher in the latter. The information exchanged between the “user and the website is protected and cannot be easily intercepted or modified by unauthorized third parties. HTTP, on the” other hand, transmits data in clear text, making it vulnerable to interception or modification.
- HTTPS uses SSL/TLS certificates to establish a secure connection. These certificates verify the “identity of the website, increasing user trust. HTTP does not involve the” use of certificates, which means there is no “verification of the” site’s identity, increasing the risk of phishing or man-in-the-middle attacks.
- By default, HTTP uses port 80 for connection, while HTTPS uses port 443. This is a technical difference that helps computers and servers distinguish between the two types of traffic.
- In the past, it was believed that HTTPS slightly slowed down performance due to the additional time needed for data encryption. However, with technological advancements and the introduction of HTTP/2, HTTPS offers comparable, if not superior, performance to HTTP.
- From an SEO (Search Engine Optimization) perspective, Google prefers HTTPS. Using HTTPS can therefore improve a site’s ranking in search results.
- Users are increasingly aware of online security. A site that uses HTTPS displays a padlock in the address bar, indicating that the connection is secure. This increases user trust and can reduce the site’s bounce rate.
In summary, while HTTP can still be used for websites that don’t exchange sensitive information, the “adoption of HTTPS is strongly recommended to ensure security, privacy,” reliability, and improve search engine rankings.

From SSL TLS to HTTP: How Protocols Have Changed Over Time
Over the years, the protocols used for internet communication security have undergone significant evolutions, moving from SSL (Secure Sockets Layer) to TLS (Transport Layer Security) and directly influencing the “use of HTTP and the” introduction of HTTPS.
1. From SSL to TLS: How They Improved Internet Connections
SSL was the first widely adopted protocol to ensure secure connections on the Internet. Since the introduction of SSL 1.0 in 1995, there have been various versions (SSL 1.0, 2.0, and 3.0) that have sought to improve communication security.
However, due to vulnerabilities and limitations in SSL versions, TLS 1.0 was developed and introduced in 1999 as its successor. Since then, TLS has continued to evolve (with versions such as TLS 1.1, 1.2, and recently 1.3) to offer stronger and more secure encryption protocols.
2. From HTTP to HTTPS: A New Era
HTTP, the standard protocol for transferring information on the web, does not encrypt data, leaving it vulnerable to interception and manipulation.
With the introduction of SSL/TLS, it became possible to protect communication between client and server, leading to the creation of HTTPS (HTTP Secure).
HTTPS encapsulates the HTTP protocol within the security layer provided by SSL/TLS, ensuring that transmitted data is encrypted and authenticated.
3. Impact on Websites
The adoption of HTTPS has become a standard practice for websites, especially for those handling sensitive information. In addition to providing an essential level of security, the use of HTTPS positively affects a website’s authority and trust, as well as its ranking in search engines.
4. Evolution and Security
Each new version of TLS has improved security compared to its predecessor, addressing known vulnerabilities and introducing more robust encryption algorithms. For example, TLS 1.3 has reduced complexity and improved security and speed compared to TLS 1.2.
5. Security in the Latest Standards
With the “evolution of cybersecurity, older versions of SSL and TLS have been gradually abandoned and considered insecure. This has pushed the” industry and web developers to adopt the latest and most secure standards.
The “evolution from SSL to TLS and from HTTP to HTTPS reflects the”growing importance of online security and privacy, and underlines the need to adopt the best practices and most up-to-date standards to protect users and information exchanged on the internet.
Warning: This Can Happen If You Don’t Use HTTPS
If you don’t use HTTPS on your website, you expose yourself to a series of significant risks that can compromise both the security of the site and the trust of your users. Here’s what can happen if you choose to stay with HTTP and not switch to the HTTPS protocol:
- Without the encryption provided by HTTPS, data sent and received by your site can be easily intercepted by malicious actors. This includes sensitive information such as passwords, personal data, financial information, and other private data.
- In a man-in-the-middle attack, an attacker can intercept and modify the data transmitted between your site and users. This could result in malicious content, such as malware or harmful scripts, which can damage both users and your site’s reputation.
- Modern web browsers flag sites that don’t use HTTPS as “not secure”. This label can drive users away from your site, reducing traffic and compromising the credibility of your online presence.
- Google and other search engines prefer sites that use HTTPS because they are more secure. Consequently, the “use of HTTP can penalize the ranking”of your site in search results, limiting visibility and user access.
- By using HTTP, your site is more susceptible to various types of cyber attacks, such as phishing or network sniffing, which exploit the lack of security in data transmission.
- Depending on the nature of your website and the type of data processed, using HTTP instead of HTTPS could put you in conflict with data protection regulations, such as GDPR in Europe. The consequences? Heavy penalties!
The use of HTTPS is a good practice for online security, and it is now an essential standard for any website. You can’t and shouldn’t do without it!

Conclusions
The transition from HTTP to HTTPS is not just a precautionary measure in “the realm of digital security. It’s a real investment in strengthening the trust and” authenticity of your website.
Remember that:
- HTTPS encrypts data during transfer, effectively preventing unauthorized access and modifications.
- Adopting HTTPS demonstrates commitment to safeguarding users’ privacy and security, and increases their trust in your site.
