In addition to Custom Sections Directory feature that allow users to set up sections on topics of interest, and to share them with other, Google now allows users to mark a story cluster by clicking on star next to it. “When you star a story in Google News, it's one way to let us know that you're interested in. When there’re significant updates, we’ll alert you by putting headline in bold. You can also follow your 20 most recent starred stories in the "Starred" section of Google News,” Google News blog informs.
Also, Google News implemented a recrawl feature that focus on getting the newest articles around while still ensuring that we're displaying most up-to-date information. “From the moment we discover a new article, we'll keep revisiting it looking for changes. Since we've noticed that most changes to articles occur just after they're published, we revisit articles most frequently in the first day after we've found them. In some cases, we'll even revisit articles we had trouble crawling first time around. After that, we visit them less often. For readers, this feature is intended to reduce number of outdated headlines and dead links you might find. And for publishers, rest assured that we'll be back to find your latest stories and updates as soon as we can,” says Google.
