It’s only anecdotal evidence, but these stats show just how powerful Google is. My site is indexed by all the major search engines – and, as you can see, a number of minor ones too – but Google represents 98% of the visits to my website that come from searches. (The graphic below shows yesterday’s traffic that come from search engines.)
It may be that people using other search engines go to other websites; that, for some reason, I have a higher ranking with Google. I don’t know, but I know that Google owns searches to Kirkville.
