Google operates about 10.5 million Web sites in October, a 411,000 increase from September, according to statistics released Thursday by Netcraft, which monitors what software is used to host Web sites. Netcraft found 182 million Web sites total, of which 10.5 million used Google’s software. Apache ran 91.5 million of htem, and Microsoft’s IIS ran 62.8 million.
That gives Google about 5.7 percent share, according to NetCraft. But the fraction rises higher to 10.6 percent when measuring “active” sites, which screens out a lot of domains that just have a token Web pages with no real content.
