On Wednesday, Google revamped its Google News homepage with several changes designed to make its news more relevant to readers. The new heart of the homepage is something called “News for you” — a stream of headlines automatically tailored to one’s interests. Readers can use the “Edit personalization” box to specify how much they’re interested in business, health, entertainment, sports or any subject they want to add. Search Engine Land: The change gives Google News a solid “middle” column of news, something that Google refers to as the “news stream.” Everyone sees the same Top Stories shown above the personalized News For You section. The personalized news, of course, will be unique to each individual.
