Google has added a new "Follow News" button that allows you to easily bookmark frequent searches and create custom sections within your personalized Google News home page.
If you do a search on Google News, you'll now likely see a "Follow [your searched query] News" button that appears at the top of the results. If you click on the button, it'll make a bookmark link to that search, added to the left hand side of Google News.
Clicking on that link will bring back search results for that topic, making it an easy way to keep track of your favorite topics.
In addition, clicking on the new Follow News button will also create a custom section of news that's added to your Google News home page.
