Twice the Sitelinks Official Google Blog December 8, 2007 As a reminder, there is a common and oft-repeated misunderstanding that Sitelinks identifies a so-called "authority site". I have never seen any evidence that this is true.
Who here uses the sitelinks? (Obviously a load of people do, but I'd love to know a little more about why xD ) Personally I don't spend enough time on a SERPs page to use them. I just scan the title and click the interesting ones.
