Doorway Pages
Doorway pages (bridge pages, portal pages, jump pages, gateway pages or entry pages) are web pages that are created for the deliberate manipulation of search engine indexes (spamdexing). A doorway page will affect the index of a search engine by inserting results for particular phrases while sending visitors to a different page. Doorway pages that redirect visitors without their knowledge use some form of cloaking. This usually falls under Black Hat SEO. If a visitor clicks through to a typical doorway page from a search engine results page, in most cases they will be redirected with a fast Meta refresh command to another page. Other forms of redirection include use of JavaScript and server side redirection, from the server configuration file. Some doorway pages may be dynamic pages generated by scripting languages such as Perl and PHP. Identification Doorway pages are often easy to identify in that they have been designed primarily for search engines, not for human beings. Sometim ...

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 susp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tumblr
Tumblr (stylized as tumblr; pronounced "tumbler") is an American microblogging and social networking website founded by David Karp in 2007 and currently owned by Automattic. The service allows users to post multimedia and other content to a short-form blog. Users can follow other users' blogs. Bloggers can also make their blogs private. For bloggers, many of the website's features are accessed from a "dashboard" interface. , Tumblr hosts more than 529 million blogs. History Development of Tumblr began in 2006 during a two-week gap between contracts at David Karp's software consulting company, Davidville. Karp had been interested in tumblelogs (short-form blogs, hence the name Tumblr) for some time and was waiting for one of the established blogging platforms to introduce their own tumblelogging platform. As none had done so after a year of waiting, Karp and developer Marco Arment began working on their own platform. Tumblr was launched in February 2007, and within two weeks ha ...

Pharming
Pharming is a cyberattack intended to redirect a website's traffic to another, fake site by installing a malicious program on the computer. Pharming can be conducted either by changing the hosts file on a victim's computer or by exploitation of a vulnerability in DNS server software. DNS servers are computers responsible for resolving Internet names into their real IP addresses. Compromised DNS servers are sometimes referred to as "poisoned". Pharming requires unprotected access to target a computer, such as altering a customer's home computer, rather than a corporate business server. The term "pharming" is a neologism based on the words "farming" and "phishing". Phishing is a type of social-engineering attack to obtain access credentials, such as user names and passwords. In recent years, both pharming and phishing have been used to gain information for online identity theft. Pharming has become of major concern to businesses hosting ecommerce and online banking websites. Soph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloaking
Cloaking is a search engine optimization (SEO) technique in which the content presented to the search engine spider is different from that presented to the user's browser. This is done by delivering content based on the IP addresses or the User-Agent HTTP header of the user requesting the page. When a user is identified as a search engine spider, a server-side script delivers a different version of the web page, one that contains content not present on the visible page, or that is present but not searchable. The purpose of cloaking is sometimes to deceive search engines so they display the page when it would not otherwise be displayed (black hat SEO). However, it can also be a functional (though antiquated) technique for informing search engines of content they would not otherwise be able to locate because it is embedded in non-textual containers, such as video or certain Adobe Flash components. Since 2006, better methods of accessibility, including progressive enhancement, have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flarf
Flarf poetry was an ''avant-garde'' poetry movement of the early 21st century. The term ''Flarf'' was coined by the poet Gary Sullivan, who also wrote and published the earliest Flarf poems. Its first practitioners, working in loose collaboration on an email mailing list, used an approach that rejected conventional standards of quality and explored subject matter and tonality not typically considered appropriate for poetry. One of their central methods, invented by Drew Gardner, was to mine the Internet with odd search terms then distill the results into often hilarious and sometimes disturbing poems, plays and other texts. Pioneers of the movement include Jordan Davis, Katie Degentesh, Drew Gardner, Nada Gordon, Mitch Highfill, Rodney Koeneke, Michael Magee, Sharon Mesmer, Mel Nichols, Katie F-S, K. Silem Mohammad, Rod Smith, Gary Sullivan and others. Overview Joyelle McSweeney wrote in the ''Constant Critic'': Joshua Clover wrote in ''The Claudius App'': In 2007, Barret ...

Spam Poetry
Spam poetry, sometimes called spoetry, is poetic verse composed primarily from the subject lines or content of spam e-mail messages. History Several writers have claimed to have created spam poetry, and consensus has not emerged about a single origin. Some early examples come from a spam poetry competition held in 2000 by the website ''Satire Wire''. Canadian poet Rob Read began writing and sending out spam poems to a group of 'subscribers' through his Daily Treated Spam email series in September, 2003. A selection from the first two years were published as ''O Spam, Poams: Selected Daily Treated Spam'' in 2005 by BookThug. Daily Treated Spam continued until 2011, and a new series, subtitled Spamdemic, began in August 2020. Animator Don Hertzfeldt began writing spam poems in his production journal in 2004. Translator Jorge Candeias wrote Portuguese "spoems" daily, between 5 May 2003 and 5 May 2004, using spam subject lines as title and inspiration. A book entitled ''Machine Langua ...

User-agent
In computing, a user agent is any software, acting on behalf of a user, which "retrieves, renders and facilitates end-user interaction with Web content". A user agent is therefore a special kind of software agent. Some prominent examples of user agents are web browsers and email readers. Often, a user agent acts as the client in a client–server system. In some contexts, such as within the Session Initiation Protocol (SIP), the term ''user agent'' refers to both end points of a communications session. User agent identification When a software agent operates in a network protocol, it often identifies itself, its application type, operating system, device model, software vendor, or software revision, by submitting a characteristic identification string to its operating peer. In HTTP, SIP,RFC 3261, ''SIP: Session Initiation Protocol'', IETF, The Internet Society (2002) and NNTP protocols, this identification is transmitted in a header field ''User-Agent''. Bots, such as Web cra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IP Address
An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication.. Updated by . An IP address serves two main functions: network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as in IPv4, and in IPv6. The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., , which is equivalent to the historically used subnet mask . The IP address space is managed globally by the Internet Assigned Numbers Authority (IA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Crawler
A Web crawler, sometimes called a spider or spiderbot and often shortened to crawler, is an Internet bot that systematically browses the World Wide Web and that is typically operated by search engines for the purpose of Web indexing (''web spidering''). Web search engines and some other websites use Web crawling or spidering software to update their web content or indices of other sites' web content. Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently. Crawlers consume resources on visited systems and often visit sites unprompted. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling agent. For example, including a robots.txt file can request bots to index only parts of a website, or nothing at all. The number of Internet pages is extremely large; ev ...

Facebook
Facebook is an online social media and social networking service owned by American company Meta Platforms. Founded in 2004 by Mark Zuckerberg with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, its name comes from the face book directories often given to American university students. Membership was initially limited to Harvard students, gradually expanding to other North American universities and, since 2006, anyone over 13 years old. As of July 2022, Facebook claimed 2.93 billion monthly active users, and ranked third worldwide among the most visited websites as of July 2022. It was the most downloaded mobile app of the 2010s.

Search Engine
A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). When a user enters a query into a search engine, the engine scans its index of web pages to find those that are relevant to the user's query. The results are then ranked by relevancy and displayed to the user. The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories and social bookmarking sites, which are maintained by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Any internet-based content that can't be indexed and searched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
