I just had to publish a post that I could title “1,000,000,000,000” (1 trillion) and Google gives me the perfect opportunity with news that its spiders have discovered that many web pages.
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!
Google stopped displaying the size of its search index at around the 30 billion mark–which prevented a “mine is bigger than yours” tussle with Yahoo. While 1 trillion is an impressive number, keep in mind that this is not actually the size of Google’s current index.
We don’t index every one of those trillion pages — many of them are similar to each other, or represent auto-generated content similar to the calendar example that isn’t very useful to searchers.
Still, 1 trillion is a big number. Need a comparison? 1 trillion is the current price for a barrel of oil!!!!
