The seldom visited fourth page.

An survey by iProspect has found what most internet users already suspect - that most people only bother to look at the first few results of a web search. It found that 62% of search engine users click on a site on the first page of results, with 90% clicking on a site within the first three pages (up from 48% & 81% in 2002).

This confirms either:

a) Search engines are amazing at doing their job
b) Searchers are amazing at doing their job
c) Searchers are lazy

I suspect that c) is the correct answer. And hope that professional searchers are digging deeper into the results pages . . .
