Citations in supplementary information are invisible

I would like to draw attention to a substantial drawback in publishing supporting scientific data online, in supplements to the printed research paper, usually because of space limitations. Unfortunately, the additional citations in this supplementary information are invisible to those services that rely on citations as a measure of the 'quality' of journals or of individual scientists, using them to determine impact factor, h-index or Scimago journal ranking, for example.
