Every user who has ever tried to download anything from the Web, or to listen or watch anything online, is familiar with the price we have to pay for obtaining the free content: watching obtrusive ads, waiting for full download, whereby download speed falls almost to zero, or even taking the risk of catching a computer virus from some suspicious site. To say nothing of the bites of your conscience - we all know that the content is put on the Web with little or no regard for copyright laws.

Fortunately, the amount of software, movies and music you can download or watch /listen quite legally (usually on the websites of their creators) has significantly grown, as of late. The problem of finding a good source to download this content has therefore an unequivocal solution. It is all the more important that the search engines know how to find these correct, official sources, instead of the "fun portals" and all the scam sites.

This analyzer is the first in the intended series of analyzers measuring the search quality for transactional queries, i.e. for queries with a narrow practical goal: to download some file, to listen to a specific piece of music, to buy tickets, to transfer money etc.
