HTTP Vs HTTPS: What’s the difference? | Next Earning

Understanding of HTTP

HTTP is the abbreviation form of HyperText Transfer Protocol. Browsers read the message from HTTP commands they are transferred to the browsers and web servers on the basis of which web page are loaded in the browser after the entry of URL in the browser. The responses of browsers and servers are taken on the basis of protocol HTTP provided by web browser. HTTP is an independent command it is executed without the knowledge and use of other commands which covered the internet before and after the arrival of HTTP command. So, HTTP is also called a stateless Protocol. HTTP is dedicated on the way of presentation of information in the internet but it is not related to the way of transferring data from one point to another.


HTTP presents data to you i.e. it presents information according to your action. When you click one button, you'll be redirected to one page when you click another button you'll be led to another page. This is what HTTP does. HTTP makes it easy to communicate to hosts and clients at the meantime it does not keep state between the exchanges of messages. When a client requests for a page, HTTP transfers it to the web server and in return host responses the information in response.

Understanding of HTTPS

HTTPS stands for Secure HyperText Transfer Protocol or HyperText Transfer Protocol Secure which is the secure version of HTTP (HyperText Transfer Protocol). The addition of Secure ('S') in the HTTPS is to make sure that the communication between the browser and website are encrypted. HTTPS generally uses one of the secure protocols among Secure Sockets Layer (SSL) and Transport Layer Security (TLS) to cipher communications. Both of them (SSL and TLS) use asymmetric system [Public Key Infrastructure (PKI)]. To cipher communications, the asymmetrical (or PKI) system uses two keys i.e. Public Key which needs to be protected strictly and Private Key which can be distributed to anyone. The private key is accessible to the owners only while public key is accessible to everyone.

As we are talking under SEO tutorials, let me take you towards SEO. Switching to HTTPS is advantageous for SEO. As HTTPS offers security, it falls under the good choices of Google. HTTPS supports SEO by verifying as site is where it's supposed to be on the server. HTTPS switched sites are more secured to visitors where tampering by third parties is prevented and all the communications are encrypted.

Major differences between HTTP and HTTPS /(comparison):

  • HTTPS is the secure HTTP i.e. HTTPS is highly secured than HTTP.
  • HTTPS uses TCP Port 443 by default whereas HTTP uses port 80 by default and it can be customized easily.
  • HTTPS is usually used to access those sites which require more security.
  • The site’s URL starts with “https://” and “http://” according the protocol used i.e. HTTP and HTTPS.
  • HTTP operates at application layer whereas HTTPS operates at transport layer.
  • Encryption isn’t required for HTTP but required for HTTPS.
  • Certificate isn’t required for HTTP but required for HTTPS.

Make sure you've gone through these when you're switching or after switching your site to HTTPS:

  • Inform search engines about the movement of your site to HTTPS from HTTP.
  • Avoid blocking HTTPS site from crawling.
  • Make your site indexed in the search engines as possible as you can.
  • Be sure about the kind of certificate you need according to your domains/site.
  • Use 2048 bit key certificates.
  • Inform and track the migration of your site in analytics software and webmaster tools.

Here, I tried my best to make my readers clear about HyperText Transfer Protocol(HTTP) and Secure HyperText Transfer Protocol(HTTPS), their similarities, their effect in search engine ranking pages (SERP) and the differences between HTTP and HTTPS.
