Went from top 5 on page 1 to 6th or deeper pages for many hot terms, but not sure if it affected anything.
On a couple of sites, I've seen big increases in the number of pages. Like from 600 to 1200 on one site, and 350 to 1500 on another site. My other sites are showing little to no changes in indexed pages. No significant traffic increases though.
Just seeing the usual flux in MSN results. Did you guys see that interview I posted about where two of the MSN Search team were talking about their engine? Pretty interesting stuff - kinda explains why their results shift like this.
