Because of "bounce" - readers of Wikimedia who leave a clicked page or other file within seconds - GLAMs and other users of Wikimedia have no idea of the real usage of their pages and other files such as images. Off-wiki we have Google Analytics and its efficient capabilities to measure page and file usage.
If there is no Wikimedia tool which at present renders this service, we need a similar tool on Wikimedia sites. As we probably should not integrate Google Analytics in Wikimedia software, it would be extremely useful to have an independent tool tailored to specific implementation needs etc. here.
