1 billion web sites in 2013
Netcraft has been tracking the number of web sites on the internet for many years. Every month, they publish their latest numbers. As of May 2012, their chart shows close to 700 million sites (the blue line is the number of unique domains, the red one is sites with unique HTML which excludes placeholder templates like landing pages for newly purchased domains):
As you can see, the growth is impressive and unimpeded. Also:
- The total number of web sites seems to follow Moore’s Law and double every 18-24 months.
- At the current rate, we will hit 1 billion sites in 2013 and 2 billion sites in 2015.
- Over the years, the number of web sites seems to be roughly equal to the number of people on the internet.
- If WordPress continues on its current trajectory, there will be 300-500 million WordPress sites by 2015.

Exciting times, especially if you have a business that focuses on the web. Curious to see what the projections, if any, are for when the next web bubble will occur – if at all.
Reblogged this on tekArtist.
It would be interesting to see what percentage of those sites are dead sites, spam, splogs, and other worthless junk. I see counting the number of sites is akin to counting the number of accounts on Facebook or Twitter, but ignoring the number of dead/garbage ones. Regardless, the numbers are astounding!
Good point. How many *active* sites are there (say, something that's been updated within the last month)? I know I personally am responsible for no fewer than 2 dead sites
Why the dip in 2010?
