A site I work with that has worked hard on improving their quality.
Quality; as in links, content, usability? (or all three?)
I manage a large number of sites and they are all up bar one, which has taken a 30% hit.
I would say in general it's only flaw over the others is longer title tags, so may be classed as 'over optimised'.
