How Many Searches Are Unique?

[peter_d]

This is a useful piece of information.

We're all aware of the idea that a huge volume of search queries are unique, right?

The question is: how many.

Google estimate:

First, I want to clarify that we do not keep searches from 1998. The 20-25% we've stated is only an estimate, which is why we gave it a wide range. We cannot compute the exact number, so we gave a ballpark number, based on some reasonable assumptions.

Another interesting point, and one a few SEOs will know, is that Google will often map unique queries to common queries.

For example:

(1) "How much does it cost for an exhaust system" will pull up results from "cost of an exhaust system."
(2) "Overhead view of bellagio pool" will pull up results from "bellagio pool pictures."
(3) "Fedora 5 losing network connections" will pull up results from "fedora 5 network configuration."
