Automatic hyperlinking

AutoLink is a feature of the Google Toolbar. Users can convert street addresses, ISBNs in a web page in their browser to links by clicking a button on Google Toolbar. The links direct the users to Google Maps for street addresses and Amazon.com for book information.[1]

Since introduced in February 2005, there has been a lot of controversy about this feature. Some webmasters expressed their concerns over the AutoLink feature claiming that Google had no rights to modify their webpages or to direct the users to a commercial website such as Amazon.

This caused Barnes & Noble, a competitor of Amazon, to link all ISBNs on their site back to themselves to prevent people clicking them to take them to their competitor.

Google sceptics compare it with Microsoft's unpopular SmartTags, which ultimately proved too controversial and were dropped.[2]
