There’s a remarkably clueless post on ZDNet today, wherein someone who should know better says that Google’s index is 25 percent smaller than it used to be. His evidence: when he checks his own name, he found only 102,000 instances, down from 135,000 in March. (Bing.com, he says, has 157,000 results.)
The technological Onanism of this aside, it’s just a dumb observation. The idea of a search engine isn’t to provide the most results. It’s to provide the most relevant results. Maybe those “missing” 33,000 results weren’t especially interesting; it’s hard to imagine that 100,000 results on anything, let alone a blogger, would be worth investigating. (And I mean, really — who keeps track of the number of results for their own name?)
Does this have anything to do with Google’s “Caffeine” update (about which I’ll write more shortly)? Possibly, but unlikely; Caffeine seems to be about speed and resources, not index size.
