Does Google give weight to posting dates?

I’m curious.  Say three people blog about the same thing, each one year apart.  Does Google give a higher ranking to the oldest (assumed to be most original) post? If it’s given weight, how would that be characterized – as a significant weight, or a negligible one? 

I know some Googler will see this and give me an answer.  Rob �



  1. Just to be clear – say I wanted to do a date-based Google search for iPhone. Can I do that easily, like this maybe?

    date: iPhone

    That would be cool.
