Google just released a new version of Google Trends that shows Google trying to estimate traffic for sites - but you do have to login first.

What I find curious is the barrier between stuff like Google Analytics, and Google Adsense. If I use Analytics and I said it is okay to disclose my stats - is there any info shared with Trends?

My attempts at looking up stats on Google-owned properties like Google.com, GMail.com, Orkut.com, etc all failed. One did get through: GrandCentral.com, clocking in with roughly 20k visitors a day.

The lag time on the statistics seems to be roughly 4-5 days.

Some interesting stuff really - YellowPages.com vs SuperPages.com vs Local.com vs Yelp.com vs CitySearch.com - it seems like all of them except for Yelp are going nowhere. YelloBook.com is even more disheartening.

One thing I do hope they add support for later are subdomains.

Oh - and that Craigslist vs Kijiji ‘battle?’ Not even close.
