4. What Is HTTP
• HTTP stands for HyperText Transfer Protocol.It is the system for transmitting and receiving
information across server and the client.
• Now the HTTP isn’t the safest way to establish a connection, the problem with HTTP though is that it is
vulnerable to people who might want to eavesdrop or see what your activity is all about

6. What Is HTTPS
• HTTPS or Secure HTTP some may call it is a combination of Hypertext Transfer Protocol(HTTP) with
SSL/TLS protocol
• HTTPS data will be sent and received in encrypted form, which adds the element of safety.

7. Working of HTTPS
• The HTTPS is nothing but is the combination of “ HTTP+SSL “.
• The SSL stands for “ SecureSocket Layer “ which is responsiblefor securing the sensitive data over the
Internet like when you are doing Netbanking, Online Payment etc.
• The HTTP Protocol woking with SSL and now called the HTTPS.
• In HTTPS, the SSL takes care over of making sure that the data goes securely over the Internet.
• To understand the SSL,you must know the concepts of “CRYPTOGRAPHY” on which the SSL is based.

9. CRYPTOGRAPHY
The Cryptography is the art or science of hiding the information.
EXAMPLE
HELLO WORLD cryptography @1#$% *&^*!
This is called the CIPHER TEXT
PLAIN TEXT

10. Difference between HTTP and HTTPS
• HTTP URL begins with “HTTP://” and for HTTPS connection it is HTTPS://
• HTTP is unsecured on other hand HTTPS is secured
• No certificates required for validation in case of HTTP. HTTPS requires SSL Digital Certificate
• No encryption in HTTP; Data encrypted before sending and receiving in HTTPS.
• Https is used in many situations, such as log-in pages for banking, forms, corporate logins, and
other applications
• It also can increase your Google search rankings. Google, which is typically pretty tight-lipped
about its search algorithm, announced back in 2014 that it would start using HTTPS as a ranking
signal.

commonly referred to as “temporarily moved.”
• This redirect doesn’t carry or pass the link value to
the new location.
• What it does do is get the user to an appropriate
location for you so that you aren’t showing them a
broken link, a 404 page not found, or an error page.

22. DoFollow
VS
NoFollow

23. What Is Nofollow Link ?
• Nofollow links attributes do not allow search engine bots to
follow link.
• That means if the website owner is linking back to you with
nofollow attributes, it does not pass on link juice.
• Only Humans will be able to follow the links.
An example of Nofollow Link:
<a href=”http://www.google.com/”rel=”nofollow”>Google</a>

24. What Is Dofollow Link ?
• Dofollow links allow google (all search engines) to follow them
and reach our website. Giving us link juice and a backlink.
• Dofollow links allow google (all search engines) to follow them
and reach our website. Giving us link juice and a backlink.
An example of Dofollow Link:
<a href=”http://www.google.com/”>Google</a>
Note: By default all the hyperlinks are dofollow. So, you don’t
need to do anything to make a link do-follow.

25. Types Of No-Follow
• Robots Meta Tag : <meta name=”robots” content=”nofollow” />
This tells bots/crawlers/spidersnot to follow links on the full page.
• Link Attribute: <a href=”http://www.google.com” rel=”nofollow”>
This tells search engines not to count the link in terms of ranking pages.
