I was checking out the official google blog and read this rather interesting statistic

“We’ve known it for a long time: the web is big. The first Google index in 1998 already had 26 million pages, and by 2000 the Google index reached the one billion mark. Over the last eight years, we’ve seen a lot of big numbers about how much content is really out there. Recently, even our search engineers stopped in awe about just how big the web is these days — when our systems that process links on the web to find new content hit a milestone: 1 trillion (as in 1,000,000,000,000) unique URLs on the web at once!” (red emphasis is mine)

This got me thinking (uh oh) – how many of these urls would be ‘disposable’ ones? eg: how many are somthing-or-other.blogspot.com

If you think of all the people who started a blog as part of a 23 things program and no longer update it. Do blogspot, wordpress, livejournal, urls count as unique urls? (I’m guessing they do)

The trillion urls is unique urls and doesn’t include duplicate pages or pages that are generated every day (such as for a calendar).

If only I had a dollar for every unique url on the web…
