Keyword
A keyword consists of a term, a number and also a combination of numbers, characters and terms.
Search engine and the keyword
The term keyword is used especially in online marketing in the field of search engines. Search engines are like a large encyclopedia. The keyword serves as a search term with which information can be found. The so-called keyword density indicates how often a keyword occurs on a website or in a document. In the field of search engine optimization, attempts are made to adjust the keyword density of a website in such a way that the website is placed high on the search engine results pages. Whether there is an optimal keyword density for the search engine ranking is disputed for a long time. A high ranking is especially crucial for operators of company websites or online stores. Companies want to attract attention, but this is only possible if the website has a high ranking.
Keyword databases
Keyword databases show which search terms are actually entered into search engines. After entering the search term, it is possible to determine in which combination and how often this search term appears or is entered in search engines. With the help of this database, the importance of the keyword for search engine optimization can be better assessed. Companies thus have the opportunity to optimize their product focus accordingly.
Keyword in computer programming
The keyword also has a great importance in the programming language. In this case, it is a word that is given a very specific meaning by the definition of the programming language used. It must not be used as the name of variables or functions. Keywords are the so-called “vocabulary” in the programming language, whereby it is tried to keep its number small around the learning of the programming language to facilitate. For further simplifications the keywords can be summarized also in categories.
