CLOAKING (DOS Extender)
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] |
Search Engine Optimization
Search engine optimization (SEO) is the process of improving the quality and quantity of Web traffic, website traffic to a website or a web page from web search engine, search engines. SEO targets unpaid traffic (known as "natural" or "Organic search, organic" results) rather than direct traffic or Online advertising, paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academic databases and search engines, 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 Keyword research, 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 sear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Directory
A web directory or link directory is an online list or catalog of websites. That is, it is a directory on the World Wide Web of (all or part of) the World Wide Web. Historically, directories typically listed entries on people or businesses, and their contact information; such directories are still in use today. A web directory includes entries about websites, including links to those websites, organized into categories and subcategories. Besides a link, each entry may include the title of the website, and a description of its contents. In most web directories, the entries are about whole websites, rather than individual pages within them (called "deep links"). Websites are often limited to inclusion in only a few categories. There are two ways to find information on the Web: by searching or browsing. Web directories provide links in a structured list to make browsing easier. Many web directories combine searching and browsing by providing a search engine to search the directory. U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
URL Redirection
URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened. Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as whewikipedia.comanwikipedia.netare automatically redirected twikipedia.org URL redirection is done for various reasons: * for URL shortening; * to prevent broken links when web pages are moved; * to allow multiple domain names belonging to the same owner to refer to a single web site; * to guide navigation into and out of a website; * for privacy protection; and * for hostile purposes such as phishing attacks or malware distribution. Purposes There are several reasons to use URL redirection: Forcing HTTPS A website may potentially be accessible over both a secure HTTPS URI scheme and plain HTTP (an insecur ...

Link Farm
On the World Wide Web, a link farm is any group of websites that all hyperlink to other sites in the group for the purpose of increasing SEO rankings. In graph theoretic terms, a link farm is a clique. Although some link farms can be created by hand, most are created through automated programs and services. A link farm is a form of spamming the index of a web search engine (sometimes called spamdexing). Other link exchange systems are designed to allow individual websites to selectively exchange links with other relevant websites and are not considered a form of spamdexing. Search engines require ways to confirm page relevancy. A known method is to examine for one-way links coming directly from relevant websites. The process of building links should not be confused with being listed on link farms, as the latter requires reciprocal return links, which often renders the overall backlink advantage useless. This is due to oscillation, causing confusion over which is the vendor si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keyword Stuffing
Keyword stuffing is a search engine optimization (SEO) technique, considered webspam or spamdexing, in which keywords are loaded into a web page's meta tags, visible content, or backlink anchor text in an attempt to gain an unfair rank advantage in search engines. Keyword stuffing may lead to a website being temporarily or permanently banned or penalized on major search engines. The repetition of words in meta tags may explain why many search engines no longer use these tags. Nowadays, search engines focus more on the content that is unique, comprehensive, relevant, and helpful that overall makes the quality better which makes keyword stuffing useless, but it is still practiced by many webmasters. Many major search engines have implemented algorithms that recognize keyword stuffing, and reduce or eliminate any unfair search advantage that the tactic may have been intended to gain, and oftentimes they will also penalize, demote or remove websites from their indexes that implement k ...

Doorway Page
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. Someti ...

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] |
Content Negotiation
Content negotiation refers to mechanisms defined as a part of HTTP that make it possible to serve different versions of a document (or more generally, representations of a resource) at the same URI, so that user agents can specify which version fits their capabilities the best. One classical use of this mechanism is to serve an image in GIF or PNG format, so that a browser that cannot display PNG images (e.g. MS Internet Explorer 4) will be served the GIF version. A resource may be available in several different representations; for example, it might be available in different languages or different media types. One way of selecting the most appropriate choice is to give the user an index page and let them select the most appropriate choice; however it is often possible to automate the choice based on some selection criteria. Mechanisms HTTP provides for several different content negotiation mechanisms including: server-driven (or proactive), agent-driven (or reactive), transparen ...

Advertising
Advertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to put a product or service in the spotlight in hopes of drawing it attention from consumers. It is typically used to promote a specific good or service, but there are wide range of uses, the most common being the commercial advertisement. Commercial advertisements often seek to generate increased consumption of their products or services through "branding", which associates a product name or image with certain qualities in the minds of consumers. On the other hand, ads that intend to elicit an immediate sale are known as direct-response advertising. Non-commercial entities that advertise more than consumer products or services include political parties, interest groups, religious organizations and governmental agencies. Non-profit organizations may use free modes of persuasion, such as a public service announcement. Advertising may also help to reassure employees ...

AdSense
Google AdSense is a program run by Google through which website publishers in the Google Network of content sites serve text, images, video, or interactive media advertisements that are targeted to the site content and audience. These advertisements are administered, sorted, and maintained by Google. They can generate revenue on either a per-click or per-impression basis. Google beta-tested a cost-per-action service, but discontinued it in October 2008 in favor of a DoubleClick offering (also owned by Google). In Q1 2014, Google earned US$3.4 billion ($13.6 billion annualized), or 22% of total revenue, through Google AdSense. AdSense is a participant in the AdChoices program, so AdSense ads typically include the triangle-shaped AdChoices icon. This program also operates on HTTP cookies. In 2021, over 38.3 million websites use AdSense. Overview Google uses its technology to serve advertisements based on website content, the user's geographical location, and other factors ...

AdWords
Google Ads (formerly Google AdWords) is an online advertising platform developed by Google, where advertisers bid to display brief advertisements, service offerings, product listings, or videos to web users. It can place ads both in the results of search engines like Google Search (the Google Search Network) and on non-search websites, mobile apps, and videos. Services are offered under a pay-per-click (PPC) pricing model. Google Ads is the main source of revenue for Alphabet Inc, contributing US$168.6 billion in 2020. History Google launched AdWords in 2000. Initially, AdWords advertisers paid for the service monthly, and Google would set up and manage their campaigns. Google soon introduced the AdWords self-service portal to accommodate small businesses and those who wanted to manage their own campaigns. In 2005, Google started a campaign management service known as 'Jumpstart'. The AdWords system was initially implemented on top of the MySQL database engine. After the sys ...

Geo Targeting
In geomarketing and internet marketing, geotargeting is the method of delivering different content to visitors based on their geolocation. This includes country, region/state, city, metro code/ zip code, organization, IP address, ISP, or other criteria. A common usage of geotargeting is found in online advertising, as well as internet television with sites such as iPlayer and Hulu. In these circumstances, content is often restricted to users geolocated in specific countries; this approach serves as a means of implementing digital rights management. Use of proxy servers and virtual private networks may give a false location. Geographical information provided by the visitor In geotargeting with geolocation software, the geolocation is based on geographical and other personal information that is provided by the visitor or others. Content by choice Some websites, for example FedEx and UPS, utilize geotargeting by giving users the choice to select their country location. The user is th ...
