Search Engine Optimization
Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic (known as "natural" or "organic" results) rather than direct traffic or paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academic search, news search, and industry-specific vertical search engines. As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. SEO is performed because a website will receive more visitors from a search engine when websites rank higher on the search engine results page (SERP). These visitors can then potentially be converted into customers. History Webmast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uniform Resource Locator
A Uniform Resource Locator (URL), colloquially termed as a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably. URLs occur most commonly to reference web pages ( HTTP) but are also used for file transfer ( FTP), email ( mailto), database access ( JDBC), and many other applications. Most web browsers display the URL of a web page above the page in an address bar. A typical URL could have the form http://www.example.com/index.html, which indicates a protocol (http), a hostname (www.example.com), and a file name (index.html). History Uniform Resource Locators were defined in in 1994 by Tim Berners-Lee, the inventor of the World Wide Web, and the URI working group of the Internet Engineering Task Force (IETF), as an outcome of collaboration started at the IETF Living Documents bi ...

Altavista
AltaVista was a Web search engine established in 1995. It became one of the most-used early search engines, but lost ground to Google and was purchased by Yahoo! in 2003, which retained the brand, but based all AltaVista searches on its own search engine. On July 8, 2013, the service was shut down by Yahoo!, and since then the domain has redirected to Yahoo!'s own search site. Etymology The word "AltaVista" is formed from the words for "high view" or "upper view" in Spanish (alta + vista); thus, it colloquially translates to "overview". Origins AltaVista was created by researchers at Digital Equipment Corporation's Network Systems Laboratory and Western Research Laboratory who were trying to provide services to make finding files on the public network easier. Paul Flaherty came up with the original idea, along with Louis Monier and Michael Burrows, who wrote the Web crawler and indexer, respectively. The name "AltaVista" was chosen in relation to the surroundings of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spamdexing
Spamdexing (also known as search engine spam, search engine poisoning, black-hat search engine optimization, search spam or web spam) is the deliberate manipulation of search engine indexes. It involves a number of methods, such as link building and repeating unrelated phrases, to manipulate the relevance or prominence of resources indexed, in a manner inconsistent with the purpose of the indexing system."Word Spy - spamdexing" (definition), March 2003, webpagWordSpy-spamdexing. Spamdexing could be considered to be a part of search engine optimization, although there are many search engine optimization methods that improve the quality and appearance of the content of web sites and serve content useful to many users. Overview Search engines use a variety of algorithms to determine relevancy ranking. Some of these include determining whether the search term appears in the body text or URL of a web page. Many search engines check for instances of spamdexing and will remove su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as ...

Meta Tag
Meta elements are tags used in HTML and XHTML documents to provide structured metadata about a Web page. They are part of a web page's head section. Multiple Meta elements with different attributes can be used on the same page. Meta elements can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes. The meta element has two uses: either to emulate the use of an HTTP response header field, or to embed additional metadata within the HTML document. With HTML up to and including HTML 4.01 and XHTML, there were four valid attributes: content, http-equiv, name and scheme. Under HTML 5, charset has been added and scheme has been removed. http-equiv is used to emulate an HTTP header, and name to embed metadata. The value of the statement, in either case, is contained in the content attribute, which is the only required attribute unless charset is given. charset is used to indicate the character set of the docu ...

Black Hat Hacking
A Black Hat (Black Hat Hacker or Blackhat) is a computer hacker who usually violates laws or typical ethical standards. The term originates from the 1950s westerns, when bad guys typically wore black hats and good guys white hats. Black hat hackers aim to hack into any system for their own profit or out of malice. Black hat is contrasted with white hat. A third category is sometimes added, the gray hat, who hacks with good intentions but at times without permission. History The terms "Black hat" come from the color scheme used in westerns from the 1950s, in which the bad guys wore black hats, and the good guys wore white or other light colors. Criminals who intentionally enter computer networks are known as "black hat hackers". They may also distribute malware that steals passwords, credit card numbers, and other personal information, holds computers hostage, or destroys files. Even though hacking has become an important tool for governments to gather intelligence, Black Hats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Hat (computer Security)
A white hat (or a white-hat hacker, a whitehat) is an ethical security hacker. Ethical hacking is a term meant to imply a broader category than just penetration testing. Under the owner's consent, white-hat hackers aim to identify any vulnerabilities the current system has. The white hat is contrasted with the black hat, a malicious hacker; this definitional dichotomy comes from Western films, where heroic and antagonistic cowboys might traditionally wear a white and a black hat, respectively. There is a third kind of hacker known as a grey hat who hacks with good intentions but at times without permission. White-hat hackers may also work in teams called " sneakers and/or hacker clubs", red teams, or tiger teams. History One of the first instances of an ethical hack being used was a "security evaluation" conducted by the United States Air Force, in which the Multics operating systems were tested for "potential use as a two-level (secret/top secret) system."

Ranking (information Retrieval)
Ranking of query is one of the fundamental problems in information retrieval (IR), the scientific/engineering discipline behind search engines. Given a query and a collection of documents that match the query, the problem is to rank, that is, sort, the documents in according to some criterion so that the "best" results appear early in the result list displayed to the user. Ranking in terms of information retrieval is an important concept in computer science and is used in many different applications such as search engine queries and recommender systems. A majority of search engines use ranking algorithms to provide users with accurate and relevant results. History The notion of page rank dates back to the 1940s and the idea originated in the field of economics. In 1941, Wassily Leontief developed an iterative method of valuing a country's sector based on the importance of other sectors that supplied resources to it. In 1965, Charles H Hubbell at the University of California, Santa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
