Linking
If you wouldn't use links to get from a page to another, you would have to open the folders (in an operating system), where the files or text files are and you would have to enter that corresponding address into the search bar of the browser. Since it is much easier to reach a site by only one click - for example if you are interested in a product and you want to switch between the product information and the picture of the product - many people use links. The linking of a website describes their involvement in the World Wide Web. Search engines use the information about a site for linking the evaluation of the relevance of the internet, and thus to the respective ranking in the search engine, because it is easily and quickly possible, to analyze the link structure of a page (with small diagnostic programs, called bots). There is internal and external linking. A domain with several pages can be compared to a promotional brochure or a program catalog. Internal links allow you to "turn over" from one page to another if both are linked. So you could, for example, jump from page 17 of a catalog to page 42, where the corresponding data can be found. An external link would now be comparable to a manufacturer portal, where you can access a data sheet. Search engines are very interested in the link structure of a page. They prefer external links and evaluate the incoming ones higher than the outgoing ones.
