SAN FRANCISCO — Google is phasing out a service that allows millions of people to personalize its home page with applications such as weather updates and stock quotes.

The customization service, known as iGoogle, will be turned off in November 2013. The mobile version of iGoogle will be discontinued at the end of this month.

Google Inc. disclosed its plans this week. The service is being swept out as part of a periodic housecleaning that has seen Google scrap more than 30 products since co-founder Larry Page became CEO 15 months ago.

Page has been trying to sharpen Google’s focus on search, advertising, video, social networking and mobile devices.

The scheduled termination of iGoogle will come eight years after Google first offered the personalization tool. It had been seen as a way to encourage people to return to Google more frequently for information they are interested in.
