World Wide Web

• The World Wide Web (www), which is also known as
  the web, refers to an information system in which
  Uniform Resource Locators (URLs) identify
  documents and other web resources. These URLs are
  accessible over the Internet and might be
  interlinked by hypertext. It is the Hypertext
  Transfer Protocol (HTTP) that transfers the
  resources of the web which can be accessed by
  users via a web browser and are published by a
  web server.

4
Web Browser

• A web browser refers to a software application
  that is used for accessing information on the
  World Wide Web. Every time that a web page from a
  particular website is requested by a user, it is
  the web browser that retrieves the relevant
  content from a web server and displays the
  particular page on the device of the user. Every
  user needs to install a web browser to connect to
  a websites server for displaying its web pages.

5
Web Server

• A web server is primarily meant to store, process
  and deliver web resources to its clients. A web
  server is a server software or a system that has
  one or more computers which run this software and
  are able to fulfil client HTTP requests over the
  Internet and also over private LANs and WANs. It
  manages client HTTP requests related to web
  resources that have to do with one or multiple of
  its configured/served websites.
• Web servers are provided by web hosting
  companies. The best web hosting companies are
  often referred to as the Best Windows Hosting
  Company or the Best Website Hosting Company or
  as the Top Cloud Hosting Company.

Web Resources

• A web resource, which is also referred to as a
  resource, denotes any digital, physical or
  abstract thing that is identifiable. Uniform
  Resource Identifiers (URIs) are used to identify
  resources. A URI is a sequence of characters that
  is unique and identifies a physical or a logical
  resource that is used by web technologies.
• The URIs that provide the means to locate and
  retrieve information resources on a network are
  referred to as Uniform Resource Locators (URLs).

8
Web Search Query

• A web search query refers to a query that is
  based on a particular search term that is entered
  into a web search engine by a user. Such a query
  is plain text or hypertext with search-directives
  that are optional. Web search queries differ
  significantly from standard query languages that
  are governed by syntax rules that are very
  strict.
• There are 3 broad types of web search queries
  that have been empirically validated. These are
  mentioned below.
• Informational queries These are the queries
  which cover broad topics that might have numerous
  relevant results.
• Navigational queries These are those queries
  that seek a single website or web page that
  belongs to an entity.
• Transactional queries These are the queries
  that reflect a users intention with regard to
  carrying out a certain action.
• There is a 4th type of query that is supported by
  search engines but isnt used frequently. It is
  referred to as a Connectivity query. Connectivity
  queries report on the connectivity of the indexed
  web graph.

9
Search Engine

• A search engine refers to a software system that
  performs Internet searches. It searches the
  Internet for a specific information in a
  systematic way. This information is specified in
  a textual web search query. The search results
  get displayed as lines of results which are often
  referred to as SERPs (Search Engine Results
  Pages). The information consists of links to web
  pages, images, videos etc. Real-time information
  is maintained by search engines with the aid of
  running an algorithm on a web crawler. The
  Internet content that cannot be searched by a web
  search engine is usually referred to as the deep
  web.

10
Web Crawler

• A web crawler is an Internet bot. It browses the
  Internet systematically, typically for Web
  indexing. It is called a spider or spiderbot as
  well. Web crawling software is used by web search
  engines and some websites for the purpose of
  updating their web content or other sites
  contents indices. Pages are copied by web
  crawlers for the purpose of being processed by a
  search engine that indexes the pages that have
  been downloaded to enable a more efficient search
  by users.
• A web crawlers behavior depends on a combination
  of certain policies. These are, a selection
  policy (the pages to download), a re-visit policy
  (when to check for changes to pages), a
  politeness policy (how to avert overloading
  sites) and a parallelization policy (how
  distributed web crawlers can be coordinated).
• Resources of the visited system are consumed by
  crawlers as well as these crawlers visit sites
  without approval. Hence, mechanisms have been
  made available to public sites to make it known
  to the crawling agent that such sites do not wish
  to be crawled.

11
SEO

• SEO is the abbreviation for Search Engine
  Optimization. It is meant to improve the quality
  as well as the quantity of the traffic to a web
  page from search engines. It is the unpaid
  traffic, which is also referred to as a natural
  or an organic result that is targeted by SEO and
  not the direct or paid traffic. Different types
  of searches, such as image or video related
  searches are the origin of unpaid traffic. Since
  it is an Internet marketing strategy, SEO takes
  into account the way search engines function,
  peoples searches, search terms (keywords), the
  most preferred search engines by the target
  audience as well as those algorithms which
  dictate search engine behavior and are
  computer-programmed.
• The purpose of carrying out search engine
  optimization is based on the fact that a website
  receives more traffic through a search engine
  when it ranks higher on the search engine results
  page. This traffic has the potential of being
  converted into customers.

12
SERP

• SERP stands for Search Engine Results Pages.
  These are those pages that get displayed online
  by search engines as a response to a particular
  query of a user. SERPs primary component is the
  listing of results that the search engine returns
  as a response to a keyword query. The ranking of
  the results is based on their relevance to the
  query. These results are generally of 2 types.
  One of these is the organic search result which
  is retrieved by the algorithm of the search
  engine and the other is the sponsored search
  result (advertisement).
• Every result that is on the SERP has a title, a
  short description and a link that directs to the
  actual web page. In the case of sponsored
  results, it is the advertiser who chooses what
  gets displayed.
