Positioning is the place of a web page in the results list, achieved by a search engine. The first condition is obviously the application of the website in the major search engines. The major search engines are those with the largest market share, because the analysis of typical user behavior shows again and again, that almost the only really big search engines are used, especially of course Google. The aim of the optimization of a website for a search engine is, that the site is positioned at the top of the results list, so the website is visited frequently by users.
