MSN update Ranks daily .Is it true?

[qaswer]

I have reado n another forum that Msn checks changing in content and links on daily basis so position of your page always change on daily bases , Is it true or just a rumor ?

[dcz]

Hard to tell if it's really performed on a daily basis, but yes, SERPS are moving faster on MSN than on Google, this is a fact.

So there must be some criteria applied more often than on other search engines to do this.
