That’s a bit of a trick question, as there isn’t a definite answer.
However, right now there are 644 million active websites on the Internet according to Netcraft.
Netcraft’s March 2012 website survey discovered 644,275,754 active websites, to be precise.
Half a billion is a lot. But when we’re talking about the Internet, sounds kind of small.
It won’t be small for long. The Internet is still growing by leaps and bounds. The March numbers were up by 31.4 million (5.1%) over last month.
Plus, nearly six million domain names were added to the Internet in the fourth quarter of 2011, bringing the total to 225 million domain names worldwide, says VeriSign. Each domain name can designate a single website or it can host lots of them.
