    The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.

    Most traditional communications media including telephone, music, film, and television are reshaped or redefined by the Internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and IPTV. Newspaper, book and other print publishing are adapting to Web site technology, or are reshaped into blogging and web feeds. The Internet has enabled or accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.

    Guidelines to create a excellent web design structure:

    Website Design Structure for SEO
    Website Design Structure for SEO
    Here at design, we decided to give developers a few tips on making a web page design construction in order to have a good flow and experience of the web page. We adhere to these recommendations as much as possible and we are positive that if you adhere to these recommendations as well, you will see quicker web page loading time, a better overall look of the web page, and search engines optimization friendly web page design. Feel free to comment on this post with your ideas and suggestions.

    Web Design Text and Content

    - Make sure the backgrounds don’t interrupt any of the text you want people to read.
    - Make sure to convey which information is most important in a hierarchy.
    - Be sure to allow the font size to be large enough for people to read, but not enormously large.
    - Separate large paragraphs into smaller, easier to read paragraphs. Large paragraphs sway people away from reading the content.


      - The navigation buttons must be easy to find and use. Try to make all navigation buttons consistent in the web design and structure throughout the website.
      - If possible, allow the visitor to know where they are at all times either by using titles, or depressed navigation buttons.
      - If possible, avoid frames at all costs. Search engines have trouble crawling content within frames and therefore is bad for search engine optimization.
      - Always include a sitemap in either .HTML or .XML format. Search engines use these to easily navigate and crawl through a site.


        - Try to make all link colors coordinate with the website colors.
        - Either make links in the content underlined, a different color, or bold so they stand out to the visitor.

          Web Design Graphics

          - Try not to make buttons too large.
          - Try to make buttons match with the look and feel of the web design.
          - Always include ALT tags for search engine optimization.
          - All graphic links should also be matched with a regular text link.
          - Graphics and backgrounds should always use browser safe colors as much as possible.
          - Try not to use too many animated graphics.
          - Try not to use too large of graphics for layout structure or buttons. This slows down the website load time.

            General Design

            - If everything is done according to this article, page download time will be fast.
            - Try to shoot for a 800 x 600 pixel resolution for the website.
            - Balance the content of pictures, text, paragraphs, and links.
            - Make every page identical to the rest of the web design.

              Search Engines

              Search Engines
              Search Engines
              A web search engine is designed to search for information on the World Wide Web and FTP servers. The search results are generally presented in a list of results often referred to as SERPS, or "search engine results pages". The information may consist of web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

              Top 5 Most Popular Search Engines

The company was founded by Larry Page and Sergey Brin, often dubbed the "Google Guys", while the two were attending Stanford University as PhD candidates.

                It was first incorporated as a privately held company on September 4, 1998, and its initial public offering followed on August 19, 2004. At that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for twenty years, until the year 2024. The company's mission statement from the outset was "to organize the world's information and make it universally accessible and useful", and the company's unofficial slogan – coined by Google engineer Amit Patel and supported by Paul Buchheit – is "Don't be evil". In 2006, the company moved to its current headquarters in Mountain View, California. more about Google search engine...

              How web search engines work

              A search engine operates in the following order:

              - Web crawling
              - Indexing
              - Searching

                Web search engines work by storing information about many web pages, which they retrieve from the html itself. These pages are retrieved by a Web crawler (sometimes also known as a spider) — an automated Web browser which follows every link on the site. Exclusions can be made by the use of robots.txt. The contents of each page are then analyzed to determine how it should be indexed (for example, words are extracted from the titles, headings, or special fields called meta tags). Data about web pages are stored in an index database for use in later queries. A query can be a single word. The purpose of an index is to allow information to be found as quickly as possible. Some search engines, such as Google, store all or part of the source page (referred to as a cache) as well as information about the web pages, whereas others, such as AltaVista, store every word of every page they find. This cached page always holds the actual search text since it is the one that was actually indexed, so it can be very useful when the content of the current page has been updated and the search terms are no longer in it. This problem might be considered to be a mild form of linkrot, and Google's handling of it increases usability by satisfying user expectations that the search terms will be on the returned webpage. This satisfies the principle of least astonishment since the user normally expects the search terms to be on the returned pages. Increased search relevance makes these cached pages very useful, even beyond the fact that they may contain data that may no longer be available elsewhere.

                When a user enters a query into a search engine (typically by using key words), the engine examines its index and provides a listing of best-matching web pages according to its criteria, usually with a short summary containing the document's title and sometimes parts of the text. The index is built from the information stored with the data and the method by which the information is indexed. Unfortunately, there are currently no known public search engines that allow documents to be searched by date. Most search engines support the use of the boolean operators AND, OR and NOT to further specify the search query. Boolean operators are for literal searches that allow the user to refine and extend the terms of the search. The engine looks for the words or phrases exactly as entered. Some search engines provide an advanced feature called proximity search which allows users to define the distance between keywords. There is also concept-based searching where the research involves using statistical analysis on pages containing the words or phrases you search for. As well, natural language queries allow the user to type a question in the same form one would ask it to a human. A site like this would be

                The usefulness of a search engine depends on the relevance of the result set it gives back. While there may be millions of web pages that include a particular word or phrase, some pages may be more relevant, popular, or authoritative than others. Most search engines employ methods to rank the results to provide the "best" results first. How a search engine decides which pages are the best matches, and what order the results should be shown in, varies widely from one engine to another. The methods also change over time as Internet usage changes and new techniques evolve. There are two main types of search engine that have evolved: one is a system of predefined and hierarchically ordered keywords that humans have programmed extensively. The other is a system that generates an "inverted index" by analyzing texts it locates. This second form relies much more heavily on the computer itself to do the bulk of the work.

                Most Web search engines are commercial ventures supported by advertising revenue and, as a result, some employ the practice of allowing advertisers to pay money to have their listings ranked higher in search results. Those search engines which do not accept money for their search engine results make money by running search related ads alongside the regular search engine results. The search engines make money every time someone clicks on one of these ads. more about Search Engines...

                Essentials of good website designing

                - Always launch the website when it is fully functional.

                  Website Hosting / Domain Registration

                  Web Hosting Service
                  Web Hosting Service

                  A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own or lease for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called collocation or Housing as it is commonly called in Latin America or France.

                  The scope of web hosting services varies greatly. The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web "as is" or with little processing. Many Internet service providers (ISPs) offer this service free to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense.

                  Single page hosting is generally sufficient only for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, Ruby on Rails, ColdFusion, and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management. For e-commerce, SSL is also highly recommended.

                  The host may also provide an interface or control panel for managing the Web server and installing scripts as well as other modules and service applications like e-mail. Some hosts specialize in certain software or services (e.g. e-commerce). They are commonly used by larger companies to outsource network infrastructure to a hosting company. more about Web Hosting Service...

                  Domain Name Registry

                  Domain Name RegistrationA domain name registry is a database of all domain names registered in a top-level domain. A registry operator, also called a network information center (NIC), is the part of the Domain Name System (DNS) of the Internet that keeps the database of domain names, and generates the zone files which convert domain names to IP addresses. Each NIC is an organisation that manages the registration of Domain names within the top-level domains for which it is responsible, controls the policies of domain name allocation, and technically operates its top-level domain. It is potentially distinct from a domain name registrar.

                  Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA), which manages the top of the DNS tree by administrating the data in the root nameservers. more about Domain Name Registration...
