That is quite easy task indeed. But trying to guess what the metric tells… that is another story. We don’t know if fast or slow moving away from quick results happends because of
- learned habbit
- trying to make one’s mind if one of results will answer to question
- one doesn’t understand totally what hits tell
- trying to figure out better search terms
- taking a coffee break
But it could be true when one has spended longer time looking at the first five she/he propably doesn’t need to see same results again.
Still… I would like to see similar results than Google and every other search egines offer. And it is more familiar to everyone. And more reliable too.
