All the major search engines use click tracking when you click out of
a search result. This data is used for ranking purposes. It's
especially useful for moderately-common searches. It's usually
implemented in javascript to make it less visible.

The referer is passed by the browser; the easiest way to get around
that is to use https (HTTPS Everywhere can help.)

blekko has a 1-click 'spam' button that makes websites disappear from
your future results. Google recently put out a Chrome extension with a
similar feature. It comes in handy when you disagree with your
favorite search engine about what spam is.
