Keyword (Internet Search)
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 Webmasters an ...

Index Term
In information retrieval, an index term (also known as subject term, subject heading, descriptor, or keyword) is a term that captures the essence of the topic of a document. Index terms make up a controlled vocabulary for use in bibliographic records. They are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. They are used as keywords to retrieve documents in an information system, for instance, a catalog or a search engine. A popular form of keywords on the web are tags, which are directly visible and can be assigned by non-experts. Index terms can consist of a word, phrase, or alphanumerical term. They are created by analyzing the document either manually with subject indexing or automatically with automatic indexing or more sophisticated methods of keyword extraction. Index terms can either come from a controlled vocabulary or be freely assigned. Keywords are stored in a search index. Common wor ...

Keyword Advertising
Keyword advertising is a form of online advertising in which an advertiser pays to have an advertisement appear in the results listing when a person uses a particular phrase to search the Web, typically by employing a search engine. The particular phrase is composed of one or more key terms that are linked to one or more advertisements. The most common form or keyword advertising, focused on payment methods, is pay per click (PPC), with other forms being cost per action (CPA) or cost per mille (CPM). The first documented attempt at keyword advertising was 1996, by the search company OpenText, just a few years after the first attempt at banner advertisements. However, the project was soon abandoned. In 1997 Yahoo!, through its partnership with Flycast Communications, successfully launched banner advertising based on keyword searches. Their concept originated from discussions in late 1996 with Chip Royce, head of online marketing for InterZine Productions of Boca Raton, Florida, ...

Keyword Clustering
Keyword clustering is a practice search engine optimization (SEO) professionals use to segment target search terms into groups (clusters) relevant to each page of the website. After keyword research, search engine professionals cluster keywords into small groups which they spread across pages of the website to achieve higher rankings in the search engine results (SERP). Keyword clustering is a fully automated process performed by keyword clustering tools. The term and the first principles were first introduced in 2015 by the Russian search engine optimization expert Alexey Chekushin. The SERP-based keyword clustering tool Just-Magic was released in the same year in Russia. Method Keyword clustering is based on the first ten search results (TOP-10) regardless of the search engine or custom settings. The TOP 10 search results are the first ten listings that a search engine shows for a certain search query. In most cases, the TOP-10 matches the first page of the search results. T ...

Reserved Word
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no user-defined meaning. A closely related and often conflated notion is a keyword, which is a word with special meaning in a particular context. This is a semantic definition. By contrast, names in a standard library but not built into the language are not considered reserved words or keywords. The terms "reserved word" and "keyword" are often used interchangeably – one may say that a reserved word is "reserved for use as a keyword" – and formal use varies from language to language; for this article we distinguish as above. In general reserved words and keywords need not coincide, but in most modern languages keywords are a subset of reserved words, as this makes parsing easier, since keywords cannot be confused ...

Keyword (linguistics)
In corpus linguistics a key word is a word which occurs in a text more often than we would expect to occur by chance alone.Scott, M. & Tribble, C., 2006, ''Textual Patterns: keyword and corpus analysis in language education'', Amsterdam: Benjamins, 55. Key words are calculated by carrying out a statistical test A statistical hypothesis test is a method of statistical inference used to decide whether the data at hand sufficiently support a particular hypothesis. Hypothesis testing allows us to make probabilistic statements about population parameters. ... (e.g., loglinear or chi-squared) which compares the word frequencies in a text against their expected frequencies derived in a much larger corpus, which acts as a reference for general language use. Keyness is then the quality a word or phrase has of being "key" in its context. Compare this with collocation, the quality linking two words or phrases usually assumed to be within a given span of each other. Keyness is a ''tex ...

Keyword (rhetoric)
Keywords are the words that academics use to reveal the internal structure of an author's reasoning. While they are used primarily for rhetoric, they are also used in a strictly grammatical sense for structural composition, reasoning, and comprehension. Indeed, they are an essential part of any language. There are many different types of keyword categories including: Conclusion, Continuation, Contrast, Emphasis, Evidence, Illustration and Sequence. Each category serves its own function, as do the keywords inside of a given category. When someone uses a search engine, they type in one or more words describing what they are looking for: 'Norwich florist' or 'cheap holidays Greece', for example. These words or phrases are known as keywords. Corpus linguistic keywords In corpus linguistics, key words are words that appear with statistically unusual frequency in a text or a corpus of texts. They are identified by software that compares a word-list of the text with a word-list bas ...

A Vocabulary Of Culture And Society
''Keywords: A Vocabulary of Culture and Society'' is a book by the Welsh Marxist academic Raymond Williams published in 1976 by Croom Helm. Originally intended to be published along with the author's 1958 work ''Culture and Society'', this work examines the history of more than a hundred words that are familiar and yet confusing: Art, Bureaucracy, Culture, Educated, Management, Masses, Nature, Originality, Radical, Society, Welfare, Work, and many others. The approach is cultural rather than etymological. Sometimes the origins of a word cast light on its meaning, but often one finds that it originally meant something quite different. Or that there has been a fierce political struggle over the 'correct' meaning. A revised and expanded edition of ''Keywords'' was published by Fontana in 1983. In 2005 Blackwell published '' New Keywords: A Revised Vocabulary of Culture and Society'', an attempt to update Williams' text. Excerpts In his essay on "Culture" within ''Keywords'', ...
