Disabling Google’s Autolink Feature
If you use Google’s Toolbar, you may have noticed an additional functionality — Autolink. Still in beta, if you click on this button, Google will link to an online map for the stated address. It can also link tracking numbers to delivery status and ISBN numbers to Amazon.com. The Autolink feature is turned off by default.
Some people see this as a resurrection of Microsoft’s Smart Tags, which placed information on your web site that you didn’t place there. However, Jeffrey Zeldman has posted information describing how to turn the Autolink feature off.
