Google will now let users know when its search results are not reliable 

Google in a blog post explained that it will suggest users check back the results around a topic that is new. This would particularly be true for breaking news or emerging topics. 

We turn to Google for every little thing we come across but not every time what the search results displays are reliable. Sometimes there could be more to what Google shows. As part of the latest development, Google will let users know when the results around a topic are changing rapidly. Google in a blog post explained that it will suggest users check back the results around a topic that is new. This would particularly be true for breaking news or emerging topics. When you spot breaking news, you might want to read about it online. If the news is a follow-up to something that has happened previously, Google will show you links related to it. But if the story is completely new and nothing related to it has ever happened in the past, Google will tell you that the results about the topic are changing rapidly.
