Web 2.0

Web 2.0 is a buzzword coined in 1999 to describe the emergence of technology and websites that extend beyond static pages to allow visitor interaction and user generated content, rather than information retrieval only. So-called Web 2.0 technologies brought about the social media revolution—allowing people to easily share interesting content with one another without using email.

Examples of Web 2.0 websites include:

  • Wikis: Collaborative content websites such as Wikipedia
  • Social networking sites: Platforms used to interact and share ideas, such as Facebook, Twitter, and LinkedIn
  • Blogs: Web logs that traditionally encourage visitor comments
  • Media sharing: Podcasts, Audio Files and Videos on platforms such as iTunes, SoundCloud, and YouTube
  • Message boards: Forums where anyone can hold conversations by posting and reading messages
  • Question and Answer sites: Where people collaborate on giving the best answers to anyone's questions, on site's like Yahoo! Answers and Quora

Web Analytics

Web Analytics is the field of Internet data and web site traffic analysis. A variety of Web analytics applications are available to collect, measure, analyze, and report website traffic. Analytics data is used to determine how various pages of a website perform, which allows site administrators to improve traffic and visitor engagement.

Common analytics measurements are unique visitors, conversion rates, bounce rates, visit duration, exit pages and many other key engagement metrics.

Web Browser

A web browser is an application used to access web pages on the Internet or other network. Web browsers function by rendering HTML code written to display web page content.

Popular web browsers include Mozilla's Firefox, Google's Chrome, Microsoft's Internet Explorer, Opera, and Safari.

Web Cache

A web cache is a system for storing web pages on a device to reduce page load times on subsequent visits.

Web browsers implement caching in the form of reserved directories that temporarily store HTML files and images. These directories are sometimes called temporary Internet files.

Search engines also cache websites, to speed web page retrieval, lower bandwidth costs, and to reduce server load.

Web Content

Web content consists of all text, images, applications, and various types of media published on the pages of a website.

Textual content is the driving force of the Web, continuously crawled and indexed by search engines for ranking according to numerous signals.

Web Crawler

("Search Bot" and "Web Spider" redirects here)

A Web crawler is a type of Internet bot; an automated program used by search engines to retrieve web content from throughout the Internet for inclusion into their search indexes.

Webmasters have some control over the rate at which of their pages are crawled and at what rate, through Robots Meta tags, a Robots.txt file.

Web Standards

Web Standards are the formally recognized, continually evolving specifications that describe technical aspects of the Web. Although Web Standards encompass a broad range of technologies, they're most commonly associated with those responsible for the consistency and future-proofing of the languages used to develop accessible web pages.

Widely recognized current Web standards include:

  • HTML5: The fifth revision of HTML, the Markup language used to structure web pages, maintained by the WHATWG and the W3C
  • CSS 2: The second revision of CSS, the style sheet language used for describing the visual presentation of web pages, maintained by the W3C
  • XML 1.0: The first revision of XML, the markup language used in many web services and applications, maintained by the W3C
  • DOM Level 3: The third revision of the DOM, a language-neutral interface for representing and interacting with objects in HTML and XML documents, also maintained by the W3C
  • ECMAScript (ECMA-262) 5.1: The scripting language behind JavaScript, JScript and ActionScript. Maintained by Ecma International (formerly ECMA), the same body that maintains the ISO 9660 file structure, JSON, and the C++/C# programming languages

Web standards help reduce the cost and complexity of web development, while increasing long-term website accessibility. See our external links on the business benefits of Web standards.

Website Accessibility


The WHATWG (Web Hypertext Application Technology Working Group) is a growing community of web developers and professionals involved in maintaining HTML and related web standards technologies. The WHATWG was founded in 2004 by individuals from Apple, Mozilla and Opera with lead editor Ian Hickson, following the W3C's decision to abandon HTML to focus on XHTML.


The WHATWG published the first public draft of HTML5 in 2008, which was eventually led to the HTML5 Recommendation released by the W3C (World Wide Web Consortium) in 2014, as a final and complete specification.

The W3C and the WHATWG continue to work together on HTML specifications; however, the WHATWG maintains a continuously evolving, versionless "living standard" of HTML, while the W3C releases what the WHATWG refers to as "snapshots, such HTML 4.01 and the current HTML5 Recommendation.

The WHATWG spec is intended to describe what browsers should aim for, introducing new features and describing reality in as much, and as accurate, detail as possible. The W3C spec is intended to follow the W3C process to REC. - whatwg.org's FAQ

Other Specifications

In addition to HTML, the WHATWG actively works on other web standard technologies, including Microdata and Web Forms 2.0

World Wide Web Consortium
Tim Berners-Lee, W3C Director and inventor of the World Wide Wide

The World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web, and publishes most of the recommendations that concern web developers. Since it's inception in 1994, the W3C has published more than 110 standards (also known as W3C Specifications), including specs for the basic coding languages of the web, such as HTML, the DOM, and CSS.

Founded by Tim Berners-Lee (inventor of the World Wide Web), the W3C's mission is:

To lead the World Wide Web to its full potential by developing protocols and guidelines that ensure long-term growth for the Web.

WYSIWYG is an acronym for What You See Is What You Get. On the Web, WYSIWYG (pronounced WIZ-ee-wig) editors are sometimes used to publish web content by those who lack experience with markup languages. WYSIWYG editors allow users to arrange and format text, images, and other web content in "design view", with HTML and CSS created by the application.

WYSIWYG editors such as Dreamweaver, are convenient for beginners, but often produce redundant, non-Web standard, un-semantic HTML, that can result in slow-loading, inefficient, difficult to maintain websites.
