Google Labs is experimenting with new features designed to improve users’ search experience. The features will appear on search results pages and help users customize and personalize their search experience.

On search results pages, if you like a result, you can move it up on the page and mark it with an orange asterisk to clearly denote it for future reference when you re-search for that keyword. If there’s a result you don’t like, axe it and you won’t need to see it again when you search for the same keyword in the future. If you want to recommend a better webpage that should appear for a keyword search, you can do that and in future searches for that keyowrd, your recommended site will appear at the top of the SERP page marked again with an orange asterisk. And, like any good tool, it not only saves your changes for future searches of the same keyword but it also allows you to undo your changes by clicking on a link to view your results in their original ordering.
