Here's one generic example where I have seen a site recover: They wanted to be sure that their service ranked for "city name" and so they included "city name" in many (15+) navigation links on every page, including the main nav bar and some footer links. Their previously good rankings took a nose dive, but returned gradually, step-wise almost, after we restored a more natural balance to the use of keywords in links.
