  • Allow users to navigate the website without having to perform any particular actions during their navigation.
  • Prevent users of technical aids from becoming disoriented when a new window opens, which will not always be perceptible and which disrupts the use of the browsing history, in particular, or hides the main window on a screen reader.
  • Improve the way content is taken into account by search engines and indexing tools.


Do not use the automatic opening of popup windows (a window opening event when a page is loaded) on the internal pages of the website.
