Time Domain is Now an Issue in Search Algorithms

More variables involved with search.

I think I know what is going on...

Search algorithms have evolved to include time rate of change of all variables.

Rate of change of links.
Rate of change of keyword density.
Length of domain registration.
Time new documents have have been established.
Rate of change of ranking in SERPS.
etc.

Think about it. There are only so many variables you can measure on a site. If you add time then the you double the number of things you can measure.

Sounds familiar. You haven't read the recent Google Patent [webmasterworld.com] by any chance? ;)

I didnt't see that thanks. Looks like different
pieces of it are referenced on other sites. I guess if I only read this forum I wouldn't be behind the times :).
