I heard some friends talking about Google's indexing percentage. They were saying that Google estimates the size of the whole internet as 5 million terabytes, and Google only indexes 0.04% of it.
Could that be true? Where can I find info about Google's indexing statistics?
ADDENDUM: I found a page containing this info: 18 Fun Interesting Facts You Never Knew About The Internet (Dec 31st, 2010). It's in number 9.
Google estimates that the Internet today contains about 5 million terabytes of data (1TB = 1,000GB), and claims it has only indexed a paltry 0.04% of it all! You could fit the whole Internet on just 200 million Blu-Ray disks.
