The signal produced in Borexino by solar neutrinos interacting in the liquid scintillator has no particular signatures that allow to distinguish it from the background on a event-by-event basis. I recall the main features of the analysis method and, in particular, I describe three procedures that have been particularly implemented in Borexino and that are essential to extract the signal from the background: the reconstruction of the event position, the pulse shape discrimination and the three fold coincidence.
