The ranking of an internet presentation by search agencies in the internet.Search services in the internetIn order to be able to inform you on something more about the right search in the internet, you should know first of all, to whom you wish to direct your search inquiry. Therefore we wish here to go into detail to the different kinds of search services without explaining the theme too much technically. Generally you can differ between three kinds of search services (and combinations thereof):
The last mentioned ones become more and more important in the today's information research. If you put now the question, "which is the best search engine?" So you can only answer: The search engine which brings me to the right sides and/or to such information which is important for me." According to newest studies already 80 % of the German people used the search engine Google in June 2006. Manually made cataloguesManually made catalogues (as Yahoo) were made by human beings and are maintained editorially. The applied pages are evaluated by an editorial office and allocated to a subjet catalogue. However, it is not always possible to allocate a website clearly to one subject. Besides the search field the inquiring person normally gets a clear schedule with most different themes. Here the inquiring person can make a preselection according to the choosen category, which brings him hierahically more and more to the desired information. Disadvantage of the catalogue services is, that the total content of the registered websites is being recorded, but only the description of the content evaluated by the editorial staff. "By means of catalogues I am - as an unexperienced user - able to get a clear view so far in order to find the real search terms for an inquiry by search engines later on." Robots - indicesThe robot generated indice consists generally of three parts. The first part of program is repsonsible for the collection of information. These "collectors" are also named Bots, Webbots, Spider or Crawler. These collectors of information follow all links of a Website. So, they record all pages of a presentation (as far as visibly linked for the Crawler) in order to change to the next linked Website and to start the same game again. After registration you send the data to the index of the relevant search engine. There the data quantity is being structured by an indice program in such a way, that it can be searched through afterwards. A further part of program values the search inquiry, links logic operators and sends the inquiry to the data servers, in order to present the results from that point. As precise the inquiry is made by logical links of terms, as more relevant are the results. At Google you can leave out the operator "and". It is sufficient to unlink individual terms by a blank. Special tracing services - MetaenginesBesides the catalogues and automised search engines there still exist specialised search engines and Metaengines for the search within different services of the internet (News groups, FTP, etc.) or of different data banks (telephone numbers, bank connections, etc. whose contents cannot be registered by spider or crawlers automatically. For the search via Metaengines the search room should be limited before, because with the search on 20-30 search engines at the same time the quantity of relevant search results increases also proportionally the quantity of garbage (junk files?) Quantity is not the same as quality - you should search at the right places and not necessarily everywhere.
