Google has finished the test phase of its Personalized Search service, which tailors a user's query results based on their previous searches, the company announced yesterday.
The free service, which requires users to sign on to it with their Google account log-in information, is now "ready for prime time", a spokeswoman said. Google accounts are free and can be obtained by providing an email address and a password.
The service is designed to learn the searching habits of individual users so that, for example, a user who is an iMac enthusiast and searches for "apple" would receive results related to Apple Computer ahead of results about the fruit.
In addition to coming out of test status, the service also has several new features, including the ability for users to create bookmarks and add labels to items in the search history that the service compiles in order to customise their query results.
Another new feature is the ability to block individual web pages or entire sites from showing up as search results. Moreover, the service is now available in 12 languages.
More information about Personalized Search, which was first launched in June of this year, is available here.
