There should be a timing measure for click-backs. If you clicked a link, spent a few minutes reading and then clicked back, that's a good result. If you clicked another link and spent 10 minutes reading and then clicked back, that's a better result. If you clicked a link and never came back, that's the best.
That is more like it. Like anything else google uses as a factor, there is no clear cut and dry method of implementing it because its not as black and white as "well result number 1 has 90%+ clickback rate so that site must not be of any use" because there are exceptions like PCInk pointed out. Each searcher is different and each search is different. If we know what the users intentions are we can better guage what they find useful and what they don't.
My main website which gets about 60% of its traffic from search engines has a 9.4% bounce rate from search engine traffic, all other traffic is listed at a 30-35% bounce rate. So that means that about 90% of my visitors from search engines found my site to be useful enough to at least take an action and interact, shouldn't that account for something in googles eyes?
