For a search term I monitor the long-time holder of spot #2 has dropped to spot #39. It's annoyed me a long time because it's an article that's syndicated and appears on many websites and even several blogs. At one point it held 3 of the top 10 spots, then 2 and for now it's got none of them after clinging tenaciously to #2 for at least 3 years. I'd call this a big change.
