Today Google Operating system posted about a personalized search experiment Google is doing with the search results. This experiment will allow you to personalize the search results by adding, moving or removing the order of search results.
In the search results page there are two buttons, one up arrow and one “x” button, you can move the search result up using up arrow button or hide the search result with x button. The Up arrow button will move the search result to the top of the page and adds orange flower like marker to make it easy for you to recognize.
These changes will be applied each time you search using the same keywords. You can also revert back to the original search results by using a link at the bottom of the page. You need to sign in to use this feature, and this is not available for everyone yet.
