Serps are massively different today then they were last night across a ton of sectors. Looks like they did a big one. Anyone seeing any trends? I'm seeing massive ranks for authority sites where I'm looking - sites like CNN ranking for big terms that make you scratch your head, lots of wikipedia and google groups esque items ranking for huge, huge terms.
Probably from the spam they've been receiving, specifically blogspot blogs ranking in multiple positions of the top 10 for highly competitive keywords like debt, mortgage, etc... Now I bet they've worked on some kind of trust/authority algo like Google (it was only a matter of time anyway). Cool.
These rankings have changed since a week now... With MSN algo - i think these changes will stay for 30 days or less
