@Ersebet - if you're simply saying that a site owner could use AdSense to improve their engagement stats like bounce rate and pageviews to improve the site's organic rank, I can accept that; traffic stats are traffic stats whether you pay for them or not.
@TOI - I get what you mean but believe G uses bounce and time on site to some degree, not just when the search ends; to agree though, time on site doesn't really count if your site tells the user what to do and they leave your site immediately to do what they were told (ends the search). No argument TOI, just playing devils's advocate; we have one of those 90% bounce rate sites too and it IS the top two and three listings depending on the query... it ends searches.
EDIT: removed a word.
