Google Operating System discovered a new experiment Google is running named Preferred Sites. In short, users who are in this experiment will be able to add a list of sites in their search preferences page as their “preferred sites.” Google will then use that information to show those sites in a higher ranking order in the Google results for that user, when it makes sense. Let me share some examples of how this works.
If you set cnn.com to be a preferred site and you are logged in to your Google account and conduct a search for space station, Google may bump up a result from CNN to the top of the Google search results. In addition, Google will clearly label why it is the top result, with a “My preferred site” label before the page’s URL. Here is a screen capture:
Google explains that you must be part of the experiment to see this option in your search preferences. Personally, I do not see it. In addition, Google said you can be as specific as a subdomain, so if you want results from CNN, just use cnn.com, but if you want results only from money.cnn.com, you can do that as well.
